Heat Treat Radio #87: Advances in Work Flow Planning Software with Jeffrey Halonen

While this Heat Treat Radio episode about the advances in work flow planning software will be more interesting to our commercial heat treating friends, we think this topic is a fascinating one that speaks to Industry 4.0 and IIoT questions. The question: How are data and human machine interfacing technologies advancing to make the heat treat experience more efficient?

Watch, listen, or read about it in this Heat Treat Radio conversation between host and Heat Treat Today publisher, Doug Glenn, and Jeffrey Halonen, CEO of Steelhead Technologies.

Doug Glenn:  We’re looking forward to talking to you today about what is a growing interest, I think, to a lot of people in this industry, primarily because of the growing of technology and data and things of that sort. I know your company is heavily invested in job shop, plant-wide, organization-wide operating systems. That’s basically what we’re going to talk about today.

The first question I wanted to ask you is, what do you think are, for job shop-type businesses, the two or three main reasons that makes them less profitable than they might otherwise be?

Jeff Halonen
Co-founder & CEO
Steelhead Technologies

Jeff Halonen:  Great question. A job shop is a unique business. They don’t have the luxury of centralized planning, or planning in advance and architecting a plant, like they might do if they are making Chevy Tahoes where an immense amount of engineering goes into build a highly efficient operation so it’s highly predictable.

A job shop, on the other hand, is the opposite of predictability. Down to what parts, what hour, what time of day, how many customers, by week, by month. . . everything changes constantly. That buys a lot of inefficiency, not because what they do is overly complicated; it’s the complexity that grows both with a high quantity of customers and a high quantity of specifications they need to build to. Then, obviously, being at the end of the end-customer’s production cycle, the lead-times are often very high pressure because you have to make up time for all of previous mistakes and missed deadlines. You’re the last step before it gets on a plane or a train or goes straight to the customer.

We’ve seen room to improve these operations from a profitability and a data standpoint. Data is not something you’re going to be able to sell out in the market. In your plant itself, it is not very valuable, but it’s the decisions you can make with that data. Specifically, this is the case when it comes to profitability. For example, if you have five to twenty different processes or lines, which one is more profitable than the other? That should be something that you understand. This is what your business does: different types of business, even different part numbers, different customers, different lead times that you offer for customers, what’s your cost versus return on that.

The other opportunity, aside from analyzing the commercial side of all of your work, is your production. If you’re a job shop, generally you are parts in and parts out, go, go, go. It’s more of a service business than a slow moving, very technical manufacture.

So, basically, every time a job comes through your shop, you should be studying — what does it take to make that job go? Anything from the quote, to closing the sale, to receiving the order, to the physical paperwork, to notifying the floor, to building a schedule, to scheduling capacity, to executing production, providing instruction information, how you collect that data, even something as simple as how do you notify customers. Are you notifying customers on the phone or an email? You do twenty to thirty orders a day, 100 orders a day — it adds up quickly.

Invoicing — how do you generate your reports? Aggregate data — that’s the other thing that we see in job shops very frequently. The actual cost of executing an order on a marginal basis can be extremely high if you have many systems; or it’s paper-based; or it’s not streamlined.

Doug Glenn:  Not just the processing of the part, in the sense of thermally processing the part, but you’re talking all the way from preparing the quote all the way through to shipping and anything at the end.

Jeff Halonen:  Absolutely, Doug. In our experience, the job shop manufacturers are pros at what they do — the actual process. They’ve been doing it for years or sometimes decades. They have it absolutely dialed. In the physical processing of the part, sometimes there is room for improvement; but a lot of times that is a fine-tuned machine. Generally, it’s the business systems that surround it.

One thing that we like to point to is the very heavy investments that the industry makes in physical, tangible goods: natural gas, land, equipment, people, automation systems  (physical automation systems). Where we see a huge opportunity is all the things you can’t actually touch and feel. It’s the digital operating system that your plant runs on, all the systems and processes that makes your business tick.

Doug Glenn: You’re talking about data in, from the very beginning of the process, all the way through. I don’t know too many companies, especially job shops, that are actually gathering that type of data. Is it possible? What are the costs involved, let’s say, of starting to gather that data from that point all the way through? It seems like that would be expensive and difficult to do.

Jeff Halonen:  Absolutely, Doug. It feels like an asymptotic target. You can try really hard, and you can make progress; but that rate at which you make progress drops off really quickly. It’s what we see as a balance of cost of data and value of the data.

It’s not that manufacturers don’t value the data; they often do make an investments to get the data. They realize quickly that, with help with the proper tools, cost ramps up really quick. They essentially hit that floor or that asymptote, if you will, really quickly. They say, “OK, we are clearly extending more effort than it’s worth; so we’re going to dial it back. We’re going to go right here. That’s where we’re setting the knob, and we’re going to run our plant.”

Unfortunately, with the tools available, that setting or their status quo tends to be paper, Excel, systems like that. If you have no system at all, not even paper, it’s very obvious that we need something. We write on paper, we highlight, we put it here, we do this, we do that, we have a whiteboard for scheduling, and you see a lot of yield from essentially those data systems.

They are rudimentary data systems, and the cost is very low. You spend a week or two, and you deploy it. You make it, run it, and get the value. Then you say, “Now, I want to track what part was in what oven at what exact time and exactly what went through. Now I want to see all the parts that went through this or that type of process. We’ve run that part number forty times — I want to see its performance every single time from a commercial standpoint. All of a sudden, the cost of obtaining that data — now you just have a wish list. You look out and say, “That’s going to be impossible. That’s way too much time to get that data.”

That’s really where deploying a centralized platform that  takes in everything from the business — anything from inventory, to quoting, to operator instructions, to timing each process, to part numbers, to shippers, to invoicing — it all really is intertwined. When you can track every single movement of every single part going through the entire process, the cost of that data drops precipitously. Especially if you have reporting integrated. Now you can generate reports that will passively collect data as your operations go on. Whatever you look at on a daily, weekly, monthly basis to essentially run your plant.

We like to say, “Digitize, automate, optimize.” To us, these are  three core steps to reducing the cost of data. First, digital. If you have no system, or you have paper, it’s very difficult to obtain actual data and actual insights from your plant. Even if you do digitize successfully, but you just have a mass of huge databases, that’s very low usability because now you need to be essentially a data scientist to go in and make it useful.

Next is automation. We need to automatically tailor the data to present profit margin. We need to automatically tailor the data to track reworks. That’s the next step because that gets us to actionable data information.

Then, the last is optimization. The optimization itself often actually happens at the plant level where the management team is now in, what I would say is, a luxurious position of having a lot of their systems digitized then automated as well.

They have the data. They have the time to address it. Now they’re in the position of optimizing their facility. That could mean focusing on marketing; that could mean pursuing a new industry — developing a new process, training your operators. It could mean anything in the world — getting a new permit from the city, for example. These are things that optimize your plant to provide as much value as possible to the world. You have the ability to do that because you’ve done your homework to get your plant into a position to action that data and have the time available as well.

Doug Glenn:  Right. You’re collecting the data that you need to make those types of decisions. I find it interesting some of the scope of the types of decisions you just mentioned, that job shops could make based on the data. That’s pretty interesting.

Let me ask you this, Jeff:  do you have any examples in the heat treat world? Or where, for example, in the heat treat world do you envision there being some real business efficiencies here? Let me preface this one other way, too:  a lot of the people that listen to this podcast are not necessarily job shops; they are what we call “captive heat treaters” who run high volume/low variability. But there are some who actually run high variability — a lot of different parts,  maybe not exceptionally high volumes, or at least smaller volumes than our captive heat treaters. I guess, addressing those guys, or even the guys that run low variability - what are the business efficiencies we could see?

Jeff Halonen: It’s going to be different from plant to plant as far as the value you’re going to have because everyone has different proficiencies and profiles like you just mentioned. If you’re in a situation where you have a very high degree of mix, one of the huge inefficiencies that we’ve seen is they want to keep a really tight lead time; but they don’t have the ability to quickly and easily schedule efficiently. They keep all of their equipment at maximum capacity, so they keep as much throughput in the plant as possible. The inefficiency essentially shows itself in the quantity of ovens - they just simply invested in more equipment and just keep more ovens hot. They essentially overcapacitize which is both acap efficiency and an opex efficiency because you have to heat, maintain and run that much more equipment. That’s an environment where you have a lot of complexity, and the scheduling required or the inability to schedule efficiently is leading to capital inefficiency.

If you’re in a position where you’re on the other end of that spectrum, as you mentioned, Doug, where you have lower variability by part number higher volume; some of the inefficiencies there can definitely be more on the data systems — the data processes. Again, scheduling — if it’s a very simple schedule, you can schedule it very quickly and easily and very efficiently because you don’t have a lot of change. It is tracking that information — where are all the parts, for example.

A lot of times it’s the administrative time. People are walking out, still trying to find where the parts are. Simple things like order status or we ran this part with this lot number or purchase order or shipper number or whatever identifier you have — we ran this six months ago, what happened to that part? Often times, something as simple as that can turn into a 20, 30, 40-minute exercise instead of just quickly finding that information.

Doug Glenn:  How about equipment inefficiencies? How can a system like yours that’s gathering all the data - how can it help us increase efficiency, just of the equipment that we have?

Jeff Halonen:  The first step, as they say, to addressing an issue is knowing you have a problem. The first step is measuring what actually happens in the real world. You can walk out into any shop and just open your eyes and things are happening, right? But your knowledge of what’s happening is almost just instantaneous. As soon as you go to the ball game later, you’ve forgotten all about that pile of parts or that empty oven that you saw. If you have a situation where at the end of the day, week, month, quarter, you have the raw numbers - we know it can do X amount of parts or racks or  pounds or whatever the metric is - and it did Y and that’s X percentage below that number, the numbers speak for themselves.

As far as what the team can do to address the problem, that could be any number of things from a plant management standpoint. That’s where it really gets into the optimization side. Although one thing might be scheduling efficiency. If we find that turnovers or essentially thermal profiles or run speeds or whatever it may be, if we have an opportunity to batch production,  increase density which might be a scheduling exercise, we might explore that.

That could also come back into business strategy — it’s all very related. For example, you might offer to expedite fees — fast turnaround at a higher price — but then lower price for long turnaround time because that now gives you the privilege of organizing your work in a more efficient way and providing the same value at a lower price. If that end customer has the time in their schedule, they can say — hey, I want to save money and have my job done in a week or so instead of 24 hours where I’m ready to pay a huge premium. That cost multiple can be dramatic and for good reason.

Doug Glenn:  I have two more questions for you. One is a little bit hypothetical. I want you to kind of take a guess  about the rate at which software and digitization, of the sort that you’re talking about, is coming into job shops. That’s the first thing. The second and last thing I want to ask  is for you to just kind of take us on a walk through, to the best that you know, a heat treat business. How might a system like yours look?

A lot of people say, “Listen, I’ve got my system in hand, I’m okay the way I am.” First, is it coming? Do you think people are going to have to get to this digitalization sooner or later?

Jeff Halonen:  I believe so, yes.  I understand you can definitely run a shop on paper. You can run it on Excel. As far as macrotrends out in the world, consider first the technology available. The team at Steelhead is obviously very competent with a lot of really great software engineers, but the tools available have progressed dramatically over the last couple of years. We’ve run into heat treating shops that are using a system they may have installed in the ‘90s. It does functionally work, but we do see a lot of symptoms, essentially adverse symptoms, to the business by choosing to use a less effective system. That usually comes in less actionable data. It does facilitate the physical paperwork needed to run your plant, but it’s not a competitive advantage. It just is kind of there, and it’s just kind of barely acceptable. The employee morale is not great - people don’t love using systems where they have to reenter data. They can’t work from home. There are so many different currents that are coming in there.

The other one is the end customers often like more and more visibility and more and more traceability into plants. Transparency, visibility, traceability. I don’t think it’s a situation where it’s going to become unviable to run a shop without really advanced technology. I do think, over time, it will be a situation where the competitive profile is one where there are clear advantages to the shops that embrace the wholistic business advantages that come with that.

Think about your customers — they’re buyers just like anyone else. Everyone loves shopping on Amazon or their favorite website. They get the notifications; they can track everything. You order a pizza at Dominos, and you can see them rolling out the dough and putting on the sauce. The predictability and the visibility is something that is really important.

I think, over time, it is certainly something that the end manufacturer is really going to continue to drive (even automotive, traceability and everything like that). As the requirements of data go up, and the competitive landscape starts to adopt more and more of this technology, it’s going to be more and more of a disadvantage in the competitive landscape to be not at the cutting edge of that technology.

Doug Glenn:  Pretty soon it’s not going to be cutting edge, is my thinking. As more and more people are adopting it, it’s going to become easier to adopt. I’m assuming it’s going to be easier to install, easier to launch into any business.

Take us through that, as a job shop. Any of either our captive heat treaters that have a high variability of products or a lot of our commercial heat treat shops which have high variability of products — how would it look? Start us as early as you can in the process and walk us through it.

Jeff Halonen:  Starting at the beginning of the process, if you say, “I’m interested. I need a system. I can just feel it. I can see it. I know there is opportunity to improve our business.” Or, “We feel like we really optimized everything about our business, but we still feel like we have restrictions on growth.” This could be — it takes a lot of energy from the management team, the ownership team that are involved. One question I like to ask is: if the business going through your business or business unit doubles, do your headaches double? Do the amount of hours you work double? To me, that’s symptomatic of room for system improvement.

Early on in the process it starts with some level of interest, some level of intrigue. I think this is something we can improve on; our plant manager is complaining that they can’t work from home. Whatever all these issues are that manifest themselves; or you’re losing jobs in quoting, and you’re not sure if you’re a high price or a low price or margins might be unclear; you’re not satisfied with the level of data. Basically, that’s generally where we start our conversations with plants.

We really take an approach of both informing about what’s possible on the tool and what’s impossible on a modern platform.  Then we also do a value assessment. How do you do this? How do you do that? That kind of third party provides a great, almost, sounding board to say, “Okay, here’s an itemized list of room for improvement.”

Honestly, that’s what really makes it compelling. When we can sit down with a potential partner and identify how we can actually improve the business in very real and definitive terms, not just insights that you can use to drive your business. Also here’s how much time you spent here, how much time you spent there. It’s a combination of calculating hard costs and hard opportunities and then the upside with the actionable insights from the system.

From there are the deployments at Steelhead. [blocktext align="center"]We do direct-to-direct service, so no third parties. A Steelhead team member will essentially go through a lot of meetings and plant walks, in some cases, and essentially reverse engineer your plant.[/blocktext] Where do parts come in the building, and then what? Then they go here? Do they always go there? Sometimes. Can they be run together? We will ask a million questions to essentially reverse engineer the flow of your plant, and then we design the system to reflect your current operations. Not - here’s a software, now bend your plant over backwards to match the software. Whether it’s quoting, workflow automation, or reporting or any of the other parts of the system, we’re going to want to ask as many questions as possible to configure the system to match your plant.

Doug, you mentioned the cost is going to go down, over time, of technology. Absolutely. Because one thing we can do very quickly since our platform is essentially kind of like a build-your-own; it’s almost like Excel except it’s Excel that is highly, highly engineered to work for this specific industry. One thing  we can do is we can prove it out really quickly. So, in just a few hours or a couple of days, we can essentially build your plant, or a part of your plant, and then run your work through your plant and say, “Okay, pick up a quote and let’s write this quote. Here’s a purchase order, let’s do the purchase order. Let’s take this tablet and go out to your plant and step it through your exact operator interfaces. Let’s collect that data. Let’s track it; let’s sit down in the conference room. Let’s pull up the reports, the inventory.

That’s one thing that we really like to do early on — whether it’s in the late sale cycle or evaluation or sale cycle or early on in deployments — is prove it works. Because one of the things we’ve seen time and time again are the horror stories with plant operating software:  we’ve tried for 18 months and we put in tens or hundreds of thousands of dollars, and we pulled the plug. We went back to whatever we were using before. So, proof of concept really quick.

The other thing is the actual deployment going fast. We like to go hot and heavy, kind of rip the Band-aid off, not drag it out over months. We like to go 2-4 weeks, training the team, iterate, iterate, iterate, test, test, test, test, test, because everyone says how it should work. We build it, and we test it and then there are always a couple of tweaks.

From there, we have a customer success team, as well. Whether it’s a phone call, email, zoom call, or training, we like to have someone available to answer the phone. Our philosophy is that your digital infrastructure isn’t something that should be optimized for low cost because we feel that the service that comes along with it — including a team of experts — is critical. Like a wiring harness for your automobile, it runs your entire plant. When your plant changes and you have changing requirements, to have “pros on your bench” to make adaptations real time in your plant is highly valuable.

Our approach is full service. We kind of own the functionality of the system in your plant — anything from the deployment to ongoing support. We’re always one degree away from engineering, as well. Occasionally when there is a bog or something is not working properly, our engineers are right there on calls with customers to make sure everything is working properly.

Doug Glenn:  They can jump into the system and reprogram, as necessary.

Jeff Halonen:  Absolutely.

Doug Glenn:  Run us through this one then, if you would: Let’s say there’s a company — and you’re going to have to take a very generic-type job shop — that has your system already. It’s fully integrated and everything is working well. What does it look like? The reason I ask this is question, is I think a lot of people have trouble envisioning what it would look like and how it would be different than what I’m doing now.

So, a company that has your system, they go to do a quote for a job, and they receive an inquiry. Is the process they follow any different than what they would have done before your system was there? Let’s just take that first step, process and RFQ: how is that going to change from if they didn’t have your system?

Jeff Halonen:  Something like quoting can be a fairly dramatic change, depending on what the current system is. Current systems can be Microsoft Word and Microsoft Outlook and maybe an Excel sheet to track the quotes. A lot of time to administer them and then there is pretty limited visibility. The transaction that we’d see there with Steelhead is that you can actually build a fully automated quote so you can define the algorithm: all of your flow charts, your Excel sheets, square root functions, looking at the mass of the part, specific gravity, material, etc. We can even reference the current price of natural gas. So, you can build models to reflect how your business runs and reference the past performance of that job.

What that looks like for quoting is that you’re able to build the quote all in one system. You might have multiple people involved in the quote: one person is working with the customer to verify requirements, verify inputs, ask questions, gather more data, and then it lands in someone else’s inbox. Now, a streamlined workflow allows the owner or the plant manager or sales manager can now approve that quote and then sending it to the customer instead of sending it through email and downloading and moving things around, we can send it right out of the platform, attach a file. We can track and see when the end customer is opening the quote. Also, your sales team has a lot of tools. They can say, “Hey, what quotes have never been opened? Hey, we should probably make a phone call. We put a lot of effort into those quotes, why don’t we call them and see what’s going on?” There are a lot more analytics but also just speed.

Another thing we’ve heard a lot is that a customer calls, they send a purchase order that references a quote to go, and find that quote can be a challenge because it’s in someone’s inbox, unread. Instead, they can have one platform to grab the quote, convert it to an order, and now you’re running production! It’s all the same data, it’s your plant. You’re not going to start quoting using different laws of physics. It’s about streamlining what you do today and replicating what you do today, but improving the customer experience, improving your team’s experience, and quoting faster, which leads to more jobs.

Everyone wants the thing quickly. If you can go from two days to two hours or from five hours to five minutes, that can have a dramatic impact on winning deals. For example, I’m in Chicago on vacation, and a customer calls, asking, “Where are my parts?” or “What happened to these parts?” Option A is you’re making phone calls back to homebase, someone is rummaging around looking for the information, and it’s not very enjoyable for you, your team, or your customer. But, it could be you put that customer even on speakerphone or mute, look for 30 seconds, and just text them the file right off your phone in real time! It’s the speed of accessing data, customer service, and actual insights, but a lot of it is workplace satisfaction.

We’ve literally been in shops where people are threatening to quit saying, “Our system is so bad” right in front of the president of the company. . . “I’ve been saying for years, we need a new system. I’m at my wit’s end because what I have to do is so painful and repetitive every day just to make the plant go.” It can manifest in a lot of different ways.

Doug Glenn:  Give me a quick history on Steelhead.

Jeff Halonen:  Steelhead Technologies was founded early in 2021 by a team of software engineers, mechanical engineers and manufacturing engineers. We started with the need of a single customer who talked about their pain. This particular customer was running on paper; whether it was contacting customers, instructing operators, tracking information, finding information, even something as simple as a customer calling with a phone call asking for information on a job, all were huge disruptions in their day. It took half an hour and they had to physically go find people and paper. Everything was in a huge storage room at the end. What the Steelhead team heard was a high degree of pain and essentially a plea for a solution. So, we founded Steelhead Technologies to address that need.

Source: Steelhead Technologies

The team has grown really quickly, and we’ve raised 2.5 million dollars in investment capital here in 2022. The team went from an original team of about 6 to up to 16 now. As I mentioned, everything is kind of the direct service model. Whether it’s sales, deployments or customer success, it’s all team Steelhead across the board. Everyone is an expert in the platform, and everyone is one degree backed up by our team of engineers. We have six engineers that work fulltime on Steelhead making it the best that we can.

Our customers are amazing. Everything that we work on is driven by a customer request, someone out in the field, using the tool and saying, “Hey, what if. . . ?” or “Hey, this could be better” or “This extra effort. . .” or “We would really like to know this. We are trying to achieve this business objective, but we need that.” That’s really where the Steelhead team excels is taking essentially what we view as requirements and building a platform to meet those requirements.

It's really exciting. What we found is that [we can really help] the job shop industry, specifically, and also the high throughput — or even the high-mixed captive shops as you mentioned — where there is no build materials, no engineering team, no design release, and no supply chain. It’s go, go, go. The assumptions change by the day, hour, or minute, and everything is fast paced. We’ve seen a huge lack of automation and data in the space. With high quality, purpose-built technology for this fast-paced, almost, service type of manufacturing, with specifically built tools, we’re able to achieve minimal effort to achieve each job. To minimize all of the administrative effort, but also aggregate extremely detailed data down to operators, part numbers, and equipment, without driving up costs or sacrificing ease of use. That’s our core strategy.

Our customers are incredible, and a lot of our recent success has been just keeping up with our customers since they’re always pitching for a new tool or feature. We roll out a couple thousand lines of code to address this and they’re like, “This is good, but it needs that.” That’s the other thing — software is a service, so we’ve long accepted that we are never going to build the software and just ship it: it’s a continual living beast, whether it’s cybersecurity, speed, everything. So much of it is service because this type of software [requires] pros to extract the maximum value from it.

Doug Glenn:  All right, last question. This is your challenge question for the session here. You, personally: What do you find most interesting and exciting about it? When you look into the future, what are you excited about?

Jeff Halonen:  What excites me the most is the transition that shops can see by adopting technology and systems whether it’s impact to the bottom line — which we’ve seen in some shops, where it’s really stunning — or something else. A marginal labor cost where one customer’s job takes three minutes and another takes nine minutes. . . The manufacturer can now address that 3X marginal labor cost with the data where, before, they were just eating it. “This customer is not profitable; we’re not doing that; we are no longer accepting batch sizes below X, because we’re armed with the data.”

What really excites me personally is the journey that each of these plants are able to go on. I also get really passionate about when I’m able to see a difference between the way things are and the way they could be. That’s what every single interaction with our partners is: we see the way that they are and we work really hard to build the best one possible. So, it’s like, hey, look at this difference? Look what we can do? It’s that sense of accomplishment on a customer basis to really get as much as is possible out of their time, resources, people and their entire enterprise.

Doug Glenn:  It’s kind of nice seeing the smile on your customer’s face, I think, right? When things go well, to be able to say, “Man, that was good!”

Well, Jeff, thanks. I really appreciate it. It’s very exciting. It sounds like you guys have got a lot of interesting things going on and, hopefully, some of our readers/listeners/viewers will be able to give you a call but thanks for joining us.

Jeff Halonen:  Thank you, Doug. Thank you very much.

Delve into Data and Digitization in the Heat Treat Realm

OC

In preparation for Heat Treat Radio episode #87 (looking at ways to increase productivity especially with data management) coming tomorrow, take a look at these three articles from the Heat Treat Today files to get you warmed up. No matter where you are in the digitization process, you'll find something to help here. 

Taking the step from a paper and whiteboard system to a computerized system is a big jump. Maybe that's been done, maybe that's still being considered. Already digital? Then there are always efficiency and organization improvements to run an even more productive shop. Lastly, what does the future hold? How best to stay on the cutting edge of data management?

Read this original content article for guidance and encouragement in the use of digital systems for the heat treat shop.


1. Heat Treat Control Panel: Best Practices in Digital Data Collection, Storage, Validation

Heat Treat Today asked six heat treat industry experts a controls-related question, "As a heat treat industry control expert, what do you see as some of the best practices when it comes to digital data collection and storage and/or validation of instrumentation precision?" This article gives reasons for why you collect and store data and some helpful ideas for making sure those records are preserved.

Contact us with your Reader Feedback!

One expert had this to say: "electronic data must be validated for precision; checked; and calibrated periodically as defined by internal procedures or customer standards. Data must be protected from alteration, and have specific accuracy and precision."

Tony Busch, sales application engineer at Control Concepts, Inc., takes a look at digital maintenance systems. These systems play a part in recording and monitoring data, and they contribute to the overall productivity of the heat treat shop. This article makes a strong case for intelligent controllers.

"Digital power controllers can calculate resistance and provide precise power control. Predictive maintenance is achieved by knowing when an element has reached its useful life. Intelligent power control includes embedded algorithms with teach function to calculate data and predict what is likely to happen next in the life of a heating element," emphasizes Busch.

3. DUAL PERSPECTIVES: The Heat Treat Shop of 2050

Global ideas emerge in this article, as two men from very different locations, give some thoughts about digitization in the next 20 years or so. Hear from each expert - one representing the European market; one representing the North American market - as they discuss the role of technology, the human element, and heat treating of the future.

Thomas Schneidewind says, "digitization must always remain only a tool, not an end in itself." He reminds readers that importance always must be placed on the human element. Doug Glenn counters with, "For commercial heat treat shops where variability is high and volumes are relatively low, much of the same will be true with less and less human interaction needed."

The Role of Heat Treat in Binder Jetting AM for Metals

OC

Additive manufacturing (AM) at a commercial scale began about 30 years ago and has expanded well beyond its original scope. As AM becomes increasingly prominent across different industries, heat treaters need to know how to handle AM parts in their shops. Learn about the history of binder jetting AM, the alloys used in this technology that require heat treatment, and what heat treaters should expect for the future.

Read why Animesh Bose of Desktop Metal thinks that binder jetting AM is only going to be used more and more in several heat treating sectors.

This article first appeared in Heat Treat Today’s December 2022 Annual Medical and Energy print edition.


Binder Jetting of Metals: Origins

Additive manufacturing (AM) at a commercial scale began about 30 years ago and has expanded well beyond its original scope. At the beginning, rapid prototyping (RP) was the name for the burgeoning technology; it emerged in the 1990s to bridge the gap between the need for quickly produced prototypes for manufacturers, not just plastic replicas. Rapid tooling (RT) of metal tooling parts joined RP R&D at this time as the research frontier for materials engineers. The current name for these technologies stands at “additive manufacturing,” or AM, though the popular terminology is simply “3D printing.”

Polymers

Developments in polymer AM also advanced rapidly with both extrusion-based technology as well as through advancements in Digital Light Processing of photopolymers. Stratasys Ltd., an American-Israeli manufacturer of 3D printers, software, and materials for polymer additive manufacturing as well as 3D-printed parts on-demand, began using a material extrusion-based process with their FFF (fused filament fabrication) technology to print parts, patented in 1989. This worked by feeding coils of polymeric materials though a printer, which would extrude the material through a small, heated chamber where the material would pass through a small orifice to extrude – or print – in a three dimensional design. This method allowed for very fine, hair-like material to print in a precise X ,Y, and Z motion, building layer by layer. Vat polymerization was another polymer AM technology that gained traction and involved photopolymer processing. Both technologies are currently used for polymeric materials. Interestingly, both processes have been adapted and are being used for metal 3D printing.

Metal AM

In 1993, an MIT engineering professor named Emanuel “Ely” M. Sachs – a man who could be considered the father of metal binder jetting technique – along with his colleagues from MIT patented the process of laying fluent, porous materials in layers between 50- to 100-micron thickness to form 3D parts. They were able to do this by spraying an organic binder on each layer of material where they wanted to increase the height of the part to produce a bonded layer in the selected area. This layering is repeated several times before the unbonded powder is removed immediately or after further processing.

One of the biggest advancements in metal AM happened in 2014 when GE Aviation combined multiple parts into one huge, complex design using a laser-based additive manufacturing method called direct metal laser melting. The end result was an airplane fuel nozzle made of 20 parts for the LEAP™ engine. All of AM came into the limelight, and direct metal laser melting – a melt-based technology – just took off.

But there were limitations to this laser process, the main one being cost and special powder requirements to layer and melt to form the part. The process was also technologically intensive and not fast enough for high volume production (as would be necessary for automotive or consumer good-type application).

Binder Jetting Technology

Binder jetting that had been developing in the early 2000s started to gain traction as a non-melt-based process for high volume mass production. Instead of melting the powder material, a binder is used to adhere the powder metal layers where needed. This method of printing results in a more uniform final part microstructure compared to the melt-based processes. ExOne, a binder jet 3D printing company, pursued the binder jetting technology using a license from MIT. In 2015, Desktop Metal was formed, and they focused on high volume mass production by binder jet using their Single Pass Jetting (SPJ™) technology. As binder jet gained traction, other companies entered the market (HP, GE, and Digital Metal). Desktop Metal recently acquired ExOne and efforts at developing standards for the technology are in full swing.

Heat Treating of AM Metals

Stainless Steels

There are two popular types of stainless steel for AM. The first is 17-4 PH, a precipitation-hardened stainless steel, which I like to call an “all purpose” stainless steel. When heat treated, one can achieve varying levels of strength, hardness, and elongation; and since it’s stainless steel it has a reasonable corrosion resistance. The aging treatments are already well-established – for example, H900, H1100, etc. The other popular grade is 316L, a non-heat treatable grade used in the food industry among others. Now, most stainless steels have chromium and nickel in decent amounts, so companies have developed a grade which is called “nickel-free stainless steel” for applications where people might be allergic to nickel. This class of alloy is also heat treatable. There are many more stainless steel grades that are being developed by the binder jet process.

Low Alloy Steels

Many low alloy steels are used in AM. For example, 4140 and 4340 have various, small amounts of alloying elements. These low alloy steels also need to be heat treated.

Tool Steels

Again, most tool steels are heat treatable. One of the most popular grades is H13; it is a tool steel that is heat treatable and can achieve fairly high hardness. It’s used for dies and other types of tooling.

Then, there is a category of tool steels known as A2 and D2; those are steels in which the strength can be changed through heat treatment.

Metal Alloys with Binder Jetting

There are also non-steel alloys that are used in binder jetting and require heat treatment. One example is nickel-based alloys, which fall in the broad category of super alloys. With some of these alloys, a heat treater would solutionize the part by taking it to a high temperature (950-1000°C), hold it for 60 minutes, and then quench in water, high pressure gas, or (in some instances) in air. The part then undergoes an aging treatment for several hours, depending on part thickness.

Additionally, there is a class of copper alloys with small amounts of zirconium and chromium that is heat treatable. These alloys have lower thermal and electrical conductivity compared to pure copper but have an advantage of higher strength and hardness over pure copper, which is very soft and malleable. For example, in applications that require additional strength and hardness compared to copper, the copper zirconium-chromium-based alloys may be appropriate since their strength and hardness can be increased by heat treatment.

This is just an introduction to the many alloys that have been used in binder jetting that need heat treatment.

Future of Binder Jet and Heat Treat

While heat treaters know about AM in the medical and aerospace industries, AM will likely gain more traction in the automotive industry. Presently, these are relatively small parts, but you will begin to see larger components coming from AM; one of the things to be aware of is that AM can create organic shapes, including all kinds of twisted and complex metal geometries. To ensure that these organic shapes do not distort or droop, larger parts must be well-supported. The development of a software known as Live Sinter™ by Desktop Metal offers the possibility of negatively distorting a complex shaped part (in the green state) so that after sintering, the part shrinks and distorts to eventually provide the desired complex shape at the end. This allows for the possibility of sintering parts either with minimal or without any support structures.

Heat treaters can also anticipate high volume AM production. This is one of the major focuses for binder jet engineers – to reduce costs for most automotive parts – as it will make AM very appealing to this cost-conscious industry.

Finally, optimizing sintering processes and related equipment for AM parts will result in meeting the production demands of the industry, and this will lead to AM parts being seen in heat treat shops more regularly. It would not be a stretch to consider (since there are heat treatments where gas atmosphere quenching at high pressures is possible), that the complete heat treatment cycle may be performed in the same furnace.

DUAL PERSPECTIVES: Government Policy and Nuclear Power Initiatives

op-ed

Changes are inevitable, but the world today is changing so rapidly that it’s constantly keeping us on our toes. Do two men from different parts of the world, both with significant experience within the heat treating community, have vastly different perspectives on the happenings in the heat treat industry?

We want to find out, so we asked a question that focuses on the world of heat treating to Thomas Schneidewind, the editor-in-chief of heat processing magazine, and Doug Glenn, the publisher and founder of Heat Treat TodayThe question: How does government policy regarding ESG in the U.S. and nuclear power initiatives in Europe impact in-house heat treaters?

Thomas’s expertise lies in the European market while Doug’s resides in the North American market. We will feature their responses in each print magazine. Will their views align? Time will tell. Enjoy this fourth installment of an ongoing column. This column was first published in Heat Treat Today’s  November 2022 Vacuum print edition.


How does government policy regarding ESG in the U.S. and nuclear power initiatives in Europe impact in-house heat treaters?

Thomas Schneidewind, Editor-in-Chief, heat processing magazine

The energy crisis paralyzes Europe. The European Union has been arguing for a long time about which energy is green. Finally, the European Commission classified both nuclear energy and gas-fired power plants as green energy production. This was a compromise between France and Germany in the discussion about the taxonomy that regulates in which energy sources investments should be made. Today, environmental associations are suing against this compromise, considering neither nuclear energy nor gas-fired power plants to be green energy.

However, the discussion is long outdated. The Russian war of aggression on Ukraine has changed energy policy. Many nuclear power plants in France are at a standstill. Germany no longer receives gas from Russia, and the sabotage of the Nord Stream 1 and 2 pipelines is a politically motivated attack on the European energy market. Today, Europe is suffering from a major energy crisis. There has never been such a crisis in the energy sector in Europe since the Second World War. There is too little energy on the European market. At the moment, the focus is on security of supply.

This crisis threatens the existence of energy-intensive companies such as heat treatment shops. The hardening industry is also coming under pressure because it cannot pay the high electricity and gas prices. Entrepreneurs must find short-term solutions to cushion the cost shock, and ensure the survival of their business -with a view to the long-term goal of decarbonization. Because in the future, process heat must be CO2 free. A clear trend in this context is the switch from gas-heated industrial furnaces to electrically heated systems, whether resistance heating or induction. Managers must face these diverse issues today and respond quickly

Experts and practitioners will be talking about sustainability, materials, processes, and innovations in heat treatment at several events this fall. For example, in October, after a two-year pandemic break, the Hardening Congress (HK) was finally held again in Cologne. Here, too, the energy crisis was a dominant topic. We are talking about the future of Europe which must compete with the U.S. Many investment decisions are being put on hold because the uncertainty in Europe is currently too large. Europe, but especially Germany, faces a new recession.

Tremendously. A distinctive mark of the U.S. is that we’ve trusted the Market – what Adam Smith called the “Invisible Hand.” We haven’t believed that economies need to be planned or managed; attempts to manage or plan an economy result in more damage than good. We’ve believed that if proper natural or biblical law guardrails are established and enforced, the economy would run itself, self-adjusting as necessary. Today, many have lost faith in the Market. Instead, we put our faith in political processes and political leaders to handle the economy. Because we’ve lost faith in the Market, questions such as the one we’re addressing today make sense to ask. Government policy should have nothing to say about the type of energy we use, the people we hire, or the ideals we hold. Nonetheless, that is NOT the world we live in, so let’s address the question.

Nuclear Power Initiatives

This is really not an initiative; it is more of a “de-initiative” – a closing down of nuclear power plants in Europe (except France) – and the incentive to do so is not economic. According to those who know, nuclear is the cheapest, most reliable form of energy, vastly less expensive than “renewables.” So, in the hands of the Market, nuclear and natural gas generation power plants would win the day. Nuclear is being abandoned for purely political reasons. The effect on heat treaters and all other consumers of electricity: higher prices for energy, either in the form of explicitly higher prices per BTU or higher taxes to incentivize more expensive “renewable” energy sources.

Environmental, Societal, and Governance

As far as ESG goes, government policies in these areas will only increase the cost of doing business.

ONE of the three categories represents an area where the government might have a right to be heard: environmental. But even there, government’s scope is vastly overplayed – that is, if you have faith in the Market! Societal and governance are recent (non-economic) constructs being forced on businesses, NOT for the benefit of the end-consumer, but for the benefit of a vocal minority who believe the world should be a certain way and are using government policies to make it so.

For in-house and commercial heat treaters, ESG pressures and government recommendations or policies will raise the cost of doing business and ultimately the cost of the final product for consumers with very little measurable benefit for anyone. For in-house and commercial heat treaters, ESG pressures and government recommendations or policies will raise the cost of doing business and ultimately the cost of the final product for consumers with very little measurable benefit for anyone.

A Quick Guide to Alloys and Their Medical Applications

OC

Contact us with your Reader Feedback!

Do you know what are the most popular alloys in the medical market? What are their applications?  This medical alloys reference graphic gives a quick overview of alloys and their specialized uses in the medical industry.

Ask average people walking along the street what metal/alloy comes to mind when they think of medical uses - things like hip and shoulder joints, the orthodontia their kids might wear, the forceps used to remove stitches - they might come up with the answer "titanium." While this certainly is correct, there are lots of other metals and metal alloys that are used in the medical industry. They probably wouldn't answer "nitinol," a titanium alloy. Nitinol is actually used in the aforementioned braces! Nitinol can be found in other things too: stents, staples, septal defect devices, etc. Take a look at the graphic to see what all these alloys, in fact, can do; you might be surprised!

Such important implements, devices, and components that are used in and on the human body need to be durable and reliable. These medical pieces can improve the quality of life (to put it mildly) or actually save a life (to put it dramatically). Some of these alloys are actually used in and around the heart and blood vessel system! Only the best of the best will do to make up these medical items; lives are literally preserved and saved with them.

What alloys have you found in medical applications? Maybe you have experience with a loved one or yourself incorporating one of these medical pieces in your life? Are you a heat treater involved in the making of these products? Let Heat Treat Today know in the Reader Feedback.

Letter from the Publisher: Beaver, Pennsylvania & Dusseldorf, Germany

Heat Treat Today publishes eight print magazines a year and included in each is a letter from the publisher, Doug Glenn. This letter first appeared in Heat Treat Today’s December 2022 Medical and Energy Heat Treat Issue print edition.


Doug Glenn
Publisher and Founder
Heat Treat Today

It’s roughly noon on November 8, 2022, and I’m sitting outside Starbucks in downtown Beaver, Pennsylvania, about 40 minutes from downtown Pittsburgh, enjoying an unseasonably mid-70s, pure blue sky day. I live another 40 minutes away near New Castle, PA, but I’m here in Beaver to see the newest Glenn grandchild and stopped at Starbucks to buy a triple-shot decaf espresso – the mid-afternoon drink of choice for my wife — which the barista’s have affectionately dubbed “Why Bother.” (Think about it . . . three shots of DECAF espresso. Why bother?)

Contact us with your Reader Feedback!

There’s plenty of human activity here in downtown Beaver. People walking and talking. Many conversations and warm greetings — handholding, smiling, kids with parents, cars passing, movement and activity everywhere.

This moment in Beaver reminds me of the Altstadt in Dusseldorf, Germany in June of any given year. Aldstadt, which means “old town,” is the hub of activity in the evening after each of the five days of Thermprocess, the world’s largest heat treating trade show held every four years at the Messe (fairgrounds) in Dusseldorf, Germany. In fact, walking and eating dinner in the Aldstadt is one of the highlights of participating in Thermprocess.

If you’ve never heard of Thermprocess and you’re involved in the heat treating industry, you need to know about it. It is one of four co-located metals trade shows held in mid-June every four years in Dusseldorf. It is an event to behold, and one highly recommended by the author of this column. In addition to Thermprocess, there is GIFA (a foundry event), NEWCAST (a casting event), and METEC (a metallurgical event). All-in-all, over 70,000 visitors and over 2,000 exhibitors flood the Messe every four years.

In 2023, Thermprocess is being held from June 12-16, and I would like to personally invite you to join me in Dusseldorf. As the largest heat treat event in the Western world (and arguably, the ENTIRE world), Thermprocess offers North American participants an opportunity to expand their view of what is happening in the heat treating/thermal processing world. And a broader perspective is exactly what we need. For those of you who have ever attended one of the larger manufacturing events here in North America, IMTS for example, Thermprocess and her three sister shows are MUCH bigger and better.

The Messe, where the event is located, is easily twice to three times the size of McCormick Place in Chicago, where IMTS is located. It would easily take you 20 minutes to walk from one end of the Messe to the other. During the full week it is open, the Messe is packed with metals-related exhibits and activities. It is not humanly possible to see all that is available to be seen.

Heat Treat Today is encouraging North American heat treat suppliers who market internationally to exhibit. We are putting together a group of like-minded North American exhibitors to join us. Assuming we get enough companies to join us, we will exhibit close to one another and share resources to make it more affordable for all concerned. We’ll share things like food & beverage, interpreters (if needed), and meeting rooms. By the way, unlike many North American shows, it is not unusual for people to actually strike deals and sign contracts at Thermprocess.

If you’re not a heat treat industry supplier, we encourage you, as a consumer of heat treat products, services, or supplies, to attend the event. The technology that you will see will be eye-opening. Please let us know if we can be helpful getting you to Dusseldorf in June 2023.
