Vacuum Induction Melting Solution from Upper NY

/ AEROSPACE HEAT TREAT, AEROSPACE HEAT TREAT NEWS, AUTOMOTIVE HEAT TREAT, AUTOMOTIVE HEAT TREAT NEWS, ENERGY HEAT TREAT, ENERGY HEAT TREAT NEWS, FOUNDRY CASTING, FOUNDRY CASTING NEWS, MANUFACTURING HEAT TREAT, MANUFACTURING HEAT TREAT NEWS

A custom-built vacuum induction melting (VIM) equipment is set to expand thermal processing for a manufacturer, whose operations already has two VIM solutions. 

The furnace will be fabricated at the Buffalo headquarters of Retech, a SECO/WARWICK Group subsidiary, to capitalize on available schedule improvements. As custom equipment, the subsidiary’s furnaces are not dependent on assembly-line style construction, so they can be fabricated and assembled just in either location.

While this client prefers not to divulge this VIM’s application, Retech’s solution can handle casting a wide range of materials used in applications from automotive and consumer products to critical, high-value equiaxed, directionally solidified, or single-crystal aerospace parts. Almost every furnace Retech makes is modified to meet the specifications and associated applications of its clients.

An investment castings manufacturer's heat treat department received a large floor-standing box furnace from a North American specialty furnace company. The furnace will be used as support in the client's tool and die production along with tempering of finished castings.

The L&L model XLE3436 box furnace from L&L Special Furnace has an effective work zone of 34” wide by 22” high by 32” deep. It is equipped with a direct-lift vertical door with a floor switch to activate. The cantilevered vertical door eliminates the need for the upright structure to reduce the overall height of the equipment.

Tom Schulz, sales manager at L&L, highlights the key role this will play for the heat treat department, saying that this type of furnace is the company's “workhorse when it comes to thermal processing.”

The inert blanketing gas enables the part to be heat-treated with minimal surface de-carb. A stack light indicates the furnace status via an audible and visual indicator light mounted on top of the control.

Additionally, the furnace is equipped with a pyrometry package that has reference control thermocouple ports along with corner locations to record the high and low points within the unit as indicated by the latest temperature uniformity survey.

The original press release from L&L Special Furnace is available upon request.

HTD Size-PR Logo

Skuld LLC announced that they had purchased the site belonging to the former Champion Foundry in Piqua, Ohio, a gray and iron foundry that had closed in March 2017. The company will continue to be focused on innovation in the metals industry, serving their clients through a number of innovations related to novel materials and manufacturing technologies.

The four buildings with nearly 32,000 square feet of space are being refurbished to be capable of casting a wide range of ferrous metals (gray, ductile iron, steels) and nonferrous metals (aluminum, brass, bronze, copper, nickel alloys). The plant will initially have 3,000 tons of capacity but plans are in place to expand to ten times that capacity in the next few years.

Skuld will be installing machining, foam blowing, a printer farm, and heat treating, adding to their current 5 small heat treat furnaces and adding to their operations, which primarily consist of lost foam casting. The new installations will aid the company as they serve the defense, tooling, and heavy equipment industries. They are also beginning to target production of heat treat fixtures and baskets.

Sarah Jordan, CEO, Skuld LLC

Production at the new site is scheduled to begin in April 2024. Sarah Jordan, CEO of Skuld LLC, commented, "Skuld is looking forward to getting our induction melting furnaces installed so that we can produce higher temperature iron, steel, and nickel alloy castings." She continued, "many [heat treaters] have custom furnace components and fixtures that require high temperature metals. These parts can have extremely long lead times, sometimes over a year, which is a problem if they are stocked out." By using their new tooling free processes, Jordan says that they can help clients drive lead times down to less than a month, if not a day for emergency spares.

Skuld is a company founded by two metallurgical engineers, Mark DeBruin and Sarah Jordan, with ties to the heat treat industry. DeBruin is the former CTO of Thermal Process Holdings. Jordan formerly worked in heat treating at Timken and Commercial Metals and was a staff engineer for Nadcap heat treat.

David Loughlin
Business Manager Wallwork HIP Centre

This second HIP from Quintus Technologies, a high pressure manufacturer with North American locations, has been contracted following Quintus completing the commissioning of the first HIP in the third quarter of 2023.

“We expected strong demand from UK castings, 3D printing, powder fabrication, and near-net-shape manufacturers. Especially, as the UK is currently under-served with hot isostatic pressing capacity,” says Wallwork HIP Centre, business manager, David Loughlin.

Adds Simeon Collins, group director of Wallwork, “Demand from customers for processing components in our first hot isostatic press has been astonishing. It is prudent to bring forward planned investment for the next HIP, knowing it will take most of 2024 to build and install. We hope to have it up and running by early 2025. Deciding to prepare pits for expansion during the first installation has proved right.”

The second HIP will be identical to the first, operating at pressures from 40 to 207 MPa (5,800 to 30,000 psi) and temperatures up to 2282°F (1250°C). It will also have the latest rapid cooling technology, as well as the capability to offer increased cycle pressures at elevated temperatures, complements engineering advances in metal 3D printing and more.
