Auto Parts Manufacturer to Increase Aluminum Production Capacity with Expansion, New Equipment

/ AUTOMOTIVE HEAT TREAT, AUTOMOTIVE HEAT TREAT NEWS, FEATURED NEWS

A global automotive parts manufacturer recently announced its plans to invest in the expansion of its Kentucky aluminum products plant.

Kobelco Aluminum Products & Extrusions Inc. (KPEX), the U.S. subsidiary of Kobe Steel, Ltd., based in Japan, expects the expansion to increase the production capacity of its plant in Bowling Green, Kentucky, in response to the growing demand for automotive extrusions and fabricated products in the United States.

Hiroaki Matsubara, Kobe Steel senior managing executive officer

Established in April 2016, KPEX manufactures aluminum extruded products for use as bumper materials and car frame materials. In November 2018, KPEX began integrated production, ranging from melting and casting to the final manufacturing process of fabrication. Plans call for new equipment for melting, extrusion, and fabrication to go into mass production in the first half of 2020. When the expansion is completed, KPEX will have two melting furnaces and two extrusion presses. Production capacity will increase to 1,000 tons per month, from the current 500 tons per month.

“Kobelco Aluminum Products & Extrusions Inc. was established in April 2016 using our technology from Japan, and with the cooperation of Kentucky officials, our customers, and all the employees working at Kobelco, we were able to successfully begin mass production here in the US,” said Hiroaki Matsubara, Kobe Steel senior managing executive officer. “And now, supported by even more robust demand for our products, we are proud to announce that we will be making our second major investment in our operations in less than two years. With that, our aim is to continue to make our contribution to the weight reduction of automobiles and to further develop our business footprint in the Bowling Green facility.”

Merry Christmas from Heat Treat Today

A Holiday Wish from the Publisher

For a large percentage of the world’s population, Christmas is about the birth of Jesus Christ, God’s gift of His Son to save a sinful world. That Gift is “the Reason for the season.” Although commercialism continues to grow, there are those diehard fans of Christmas who try to preserve the real meaning and significance of the holiday. Christmas is about giving. (Speaking of “die hard,” my son and I just finished watching Die Hard 1, the classic “Christmas” movie starring Bruce Willis. It may be “classic,” but it doesn’t appear to have anything to do with “the reason for the season.” Nonetheless, you might enjoy it . . . especially if you have teenage or 20-something men in your home.)

One of my favorite quotes about “giving” is from a Christian missionary named Jim Elliot. “He is no fool who gives [away] what he cannot keep,” said Elliot, “to gain what he cannot lose.” He was referring to giving away of one’s physical life (which you can’t keep) to gain eternal life (which you can’t lose). Mr. Elliot, at the young age of 28, did that exact thing — gave his physical life trying to share the Source of eternal life with others. You can read more about his story here.

Since “giving” characterizes the season, I’d like to give a “thank you” to some of the people who have helped Heat Treat Today grow to be a leading heat treat industry media brand in 2018.

First, thanks to all of the manufacturers with in-house heat treat departments, especially in the aerospace, automotive, medical, and energy sectors who read our content or listen to our Heat Treat Radio podcasts. Our hope is that you’ll continue to find the content we provide more and more helpful in your work. You’re the ones we have in mind every time we prepare our content for publication. Please let us know if we can be more helpful.

Thanks also goes to the growing number of heat treat industry suppliers who are finding Heat Treat Today an effective way to get the word out about their products or services. It’s these industry suppliers who pay the bills and make this venture possible. Thank you, friends!

Finally, thank you to the people who make Heat Treat Today happen every day!

Thank you, Laura Miller, editor, for your faithful labors. You’re a joy to work with, and you deserve much more recognition than you receive.

Thank you, Brandon Glenn, web design manager and nephew (not son) of yours truly. Brandon, your help has been invaluable and your passion for the true Reason for the season is something I pray grows and grows. Thanks for all your help.

Thanks to Jonathan Lloyd for his work on Heat Treat Radio and CONGRATULATIONS for completing just days ago his undergraduate studies in audio/visual arts. Jonathan, you will be successful. Keep your eyes on the Reason for the season as you progress through life.

Heat Treat Today has added several other helpers this year including Meredith Egeland (formerly Meredith Glenn, my daughter) who helps with social media, Kelly Condon (mother of Jonathan Lloyd) who has helped with accounting and billing, and Michelle LaMay who recently joined us to help with editorial content.

Second to last and most cherished in my heart is the lovely and gracious Mrs. Glenn (Mary) who makes every day a joy. Thanks for your help!

Finally, thanks to the One who gives all of us on the Heat Treat Today team the ability to do anything worthwhile, Jesus Christ, the real Reason for Christmas.

Blessings to you and your families from the Heat Treat Today family.

Heat Treat Today will not publish content December 24–January 1. We’ll return with new and exciting content on January 2, 2019. Be safe.

IHEA 2019 Annual Meeting To Coincide with 90th Anniversary

/ HEAT TREAT ECONOMIC NEWS

IHEA will celebrate its 90th anniversary at the 2019 Annual Meeting scheduled April 29-May 1 at the Lido Beach Resort in Sarasota, Florida. IHEA members look forward to the camaraderie created by the social events and the thought-provoking presentations the meeting offers. There are also plenty of opportunities to get involved with important industry-related developments while exploring new business contacts and growing relationships.

The IHEA Welcome Reception will kick off the event on the pool deck overlooking Lido Beach and the Gulf of Mexico. The program follows with relevant keynote sessions and committee meetings to discuss association business. Sprinkle in a more “laid back” annual president’s gala, a golf tournament and discovering local attractions, and it’s the perfect mix of business and pleasure. It’s a great way to keep current with industry trends and keep in touch with peers. A previous annual meeting attendee stated, “The IHEA Annual Meeting was thoughtfully structured; we learned a lot, made some new friends and business connections and had fun doing it!”

The beautiful resort is located on one of Florida’s best beaches, featuring soft white sand that stretches for miles. The resort is close to world-famous Siesta Key beach, often voted the best beach in the U.S. The Lido Beach Resort is also just minutes from the very popular St. Armand’s Circle, filled with restaurants and shops and accessible by resort shuttle or a short five-minute walk.

Complete meeting details and registration information can be found at www.ihea.org in early 2019. We hope to see you in Sarasota next April.

Gas Fan Quench-Cooled Vacuum Hot Press Installed for Aerospace Service Supplier

/ AEROSPACE HEAT TREAT, AEROSPACE HEAT TREAT NEWS, FEATURED NEWS, QUENCHING NEWS

The world’s first 100-ton vacuum hot press with gas fan quench cooling capability for up to a 4,000 pound part has recently been installed and is in operation at a commercial and aerospace diffusion bonding operation in Chandler, Arizona.

Refrac Systems selected Solar Manufacturing, part of the Solar Atmospheres family of companies and based in Souderton, Pennsylvania, to perform the installation and startup of a large 100-ton force vacuum hot press that includes a 2-Bar Gas Fan Quench cooling system (GFQVHP). The furnace hot zone was modified to contain 100-ton on load hydraulic ram centered over the zone which is configured to diffusion bond parts up to 36″ wide x 48″ long x 30″ tall. Besides being specifically designed to diffusion bond large plastic injection molding dies, and concurrently quench hardening them, the system is finding applications in bonding advanced superalloy heat exchangers where the quench cooling offers a significant improvement on performance.

“We really drew on the extensive engineering experience base that Solar Manufacturing has for building large gas fan quench cooled vacuum furnaces coupled with our own vacuum hot pressing experience to build this very unique hot press system,” said Norm Hubele, President of Refrac Systems. “Solar’s engineering team really helped out with a lot of great design ideas and manufacturing experience, and the system really contains the most robust and reliable furnace engineering content that both companies could muster.”

“Norm put together a team of engineers to design and build this state-of-the-art GFQVHP, and it contains many innovations,” said William Jones, CEO of Solar Atmospheres. “Throughout the entire process, Norm personally reviewed all aspects of the design and added considerable insight to the development of this unique vacuum furnace system.”

Heat Treat Tips: Quenching

/ FEATURED NEWS, MANUFACTURING HEAT TREAT, MANUFACTURING HEAT TREAT NEWS, QUENCHING TECHNICAL CONTENT

During the day-to-day operation of heat treat departments, many habits are formed and procedures followed that sometimes are done simply because that’s the way they’ve always been done. One of the great benefits of having a community of heat treaters is to challenge those habits and look at new ways of doing things. Heat Treat Today‘s 101 Heat Treat Tips, tips and tricks that come from some of the industry’s foremost experts, were initially published in the FNA 2018 Special Print Edition, as a way to make the benefits of that community available to as many people as possible. This special edition is available in a digital format here.

In today’s Technical Tuesday, we continue an intermittent series of posts drawn from the 101 tips. The category for this post is Quenching, and today’s tips–#8, #38, and #81–are from three different sources: Dan Herring,  “The Heat Treat Doctor®”, of The Herring Group; Combustion Innovations; and Super Systems, Inc. 

Heat Treat Tip #8

14 Quench Oil Selection Tips

Dan Herring,  “The Heat Treat Doctor®”, of The Herring Group

Here are a few of the important factors to consider when selecting a quench oil. 

  1. Part Material – chemistry & hardenability 
  2. Part loading – fixturing, girds, baskets, part spacing, etc. 
  3. Part geometry and mass – thin parts, thick parts, large changes in section size 
  4. Distortion characteristics of the part (as a function of loading) 
  5. Stress state from prior (manufacturing) operations 
  6. Oil type – characteristics, cooling curve data 
  7. Oil speed – fast, medium, slow, or marquench  
  8. Oil temperature and maximum rate of rise 
  9. Agitation – agitators (fixed or variable speed) or pumps 
  10. Effective quench tank volume 
  11. Quench tank design factors, including number of agitators or pumps, location of agitators, size of agitators, propellor size (diameter, clearance in draft tube), internal tank baffling (draft tubes, directional flow vanes, etc.), flow direction, quench elevator design (flow restrictions), volume of oil, type of agitator (fixed v. 2 speed v. variable speed), maximum (design) temperature rise, and heat exchanger type, size, heat removal rate in BTU/hr & instantaneous BTU/minute.
  12. Height of oil over the load 
  13. Required flow velocity through the workload 
  14. Post heat treat operations (if any) 

Submitted by Dan Herring,  “The Heat Treat Doctor®”, of The Herring Group.

Heat Treat Tip #38

Oil and Water Don’t Mix

Keep water out of your oil quench. A few pounds of water at the bottom of an IQ quench tank can cause a major fire. Be hyper-vigilant that no one attempts to recycle fluids that collect on the charge car.

Submitted by Combustion Innovations

Heat Treat Tip #81

Quench Oil Troubles

According to Super Systems, Inc., there are one of three problems to consider if your quench is just not cutting it. Although SSI focuses more on atmosphere control systems, when parts come out soft, the problem isn’t always the atmosphere – sometimes it’s the quench. Here are three things to consider regarding your quench:

  • First, check the composition of the quench media. Is it up to spec? Does it need to be refreshed?
  • Is the quench receiving adequate agitation to thoroughly quench the load?
  • Is the quench at the right temperature? If the bath is too warm when the load enters, quenching won’t go well!
