A heat treat company based in Waukesha, WI, has expanded with a 95,000 square foot building in New Berlin, WI. The New Berlin facility is seven miles from their Travis Road campus.
Steve Wiberg and Mary Wiberg Springer, owners of ThermTech, share that the plant’s square footage will be 270,000. The new space will be used for the company’s expansion. The new facility will allow the heat treater to continue to meet their clients’ needs as they expand their core offerings: hardening, tempering, surface heat treatment, carburizing, vacuum treatments, annealing, press quenching, austempering, and aluminum heat treatment.

Three electrically heated RO pit furnaces with air-cooled fans have been shipped from Riverside, MI. The furnaces will be used for heat treating various steel components.
“These pit furnaces are designed for a nitrogen atmosphere,” commented Kelley Shreve, general manager at Lindberg/MPH. “They have been designed to utilize three independent heating zones for optimal temperature uniformity and meet AMS 2750G Class 3.”
These heat treating pit furnaces from have a maximum temperature rating of 2,000°F and are designed to handle a wide range of part sizes. Two of the units have work chamber dimensions of 28″ x 36” and a maximum gross workload of 2,000 lbs. each. The third furnace has work chamber dimensions of 60” x 109” and a maximum gross workload of 20,000 lbs.
All of the pit furnaces have pneumatically operated lids with three-way hand control valves and limit switches that disconnect power to the heating elements when the covers are open. The pit furnaces are electrically heated with heavy duty rod overbend heating elements.

A roller hearth iso-thermal annealing line for steel automotive impression forgings is to be installed for a major American producer located in North Carolina.
The system comes from CAN-ENG Furnaces International Limited. It will be capable of both iso-thermal annealing and normalizing with a high temperature furnace operating under exothermic atmosphere. The line includes a separate low temperature roller hearth furnace, automatic bin dump and loading system, integrated tray/basket return system, and level II automation technology. The time frame for the heat treat line installation is in Q2, 2024.
Prior to the sale of this heat treat furnace, the furnace supplier had provided a mesh belt normalizing furnace, cast link belt normalizing furnace, and a roller hearth iso-thermal annealing furnace to the forgings producer.

A global developer of power generation systems is planning to expand heat treat capabilities with a 2-bar vacuum furnace.
SECO/VACUUMwas awarded this contract and will provide a Vector® single chamber high-pressure quench vacuum furnace to expand the company's processing capacity, including high vacuum sintering and annealing. The new furnace will provide deep vacuum levels needed for the global developer's highly specialized applications.
"Securing continued business with this [client] is about working with people as much as it is working with machines," commented, Peter Zawistowski, managing director of SECO/VACUUM. This order is for a nearly identical furnace to one the same heat treat client ordered last year, which "really validated not just our furnace quality but also the teamwork and customer service behind it."

A gas generator was recently installed for Jomarca, one of the biggest manufacturers of fasteners, bolts, nuts, and fixing elements in Brazil. The generator will supply exothermic gas to a continuous wire annealing furnace, which is part of the manufacturer’s efforts to meet market demand efficiently and sustainably for baling wire in the construction industry.
Using exothermic gas instead of nitrogen, the company expects to reduce operating costs, increase production efficiency, and improve the wear properties and finish of its wire products.
“By providing them with our latest generator technology," commented Marcio Boragini, sales director for Brazil at UPC-Marathon, "we have helped Jomarca improve process efficiency, achieve sustainability, and exceed their customers’ expectations for high-quality wire products.”
Jomarca already owns two endothermic gas generators from UPC-Marathon, a Nitrexcompany with headquarters in North America. In March of this year, the company upgraded its wire operations with a 150 m3/h capacity ExoFlex generator to ensure consistent gas composition and prevent scale formation on the wire surface.

North American Stainless (NAS), a stainless steel producer in the United States, will proceed with a $244 million expansion to its Ghent, Kentucky facility in Carroll County. This expansion adds 70 new jobs to the plant.
For its 13th expansion since 1990, NAS will build a new cold rolling mill, roll grinders, an extensive upgrade of its annealing and pickling lines to support the new rolling mill, a new temper mill and the expansion of the Melt Shop Building to include a 400-metric ton crane. The new expansion will grow NAS’ 4.4 million-square-foot facility in Carroll County. NAS offers a full range of stainless flat and long products. All of NAS’ production lines are located onsite at its 1,600-acre headquarters.
Andy Beshear Governor of Kentucky
"Our latest expansion will bring more clean, sustainable and American-made stainless to consumers and directly compete with the subsidized imports of stainless,” said Cristobal Fuentes, CEO at NAS. “Our parent company Acerinox was eager to further invest in Kentucky to demonstrate its commitment to our customers and the U.S. market.”
“I’m excited to announce more growth in Kentucky’s metals industry with this latest investment from North American Stainless,” said Andy Beshear, Governor of Kentucky.

The Philadelphia Mint recently began a round of upgrades for its heat treat furnaces. Their function in the minting process is to anneal, clean, and dry the coin blanks to soften the metal prior to striking into coins, extending the service life of the striking dies.
SECO/WARWICK Group’s American subsidiary, located in Meadville, PA, recently began upgrades, a refurbishment of all five of the Philadelphia Mint’s heat-treating furnaces, one furnace per year. The heat-treating furnaces were originally installed there by SECO/WARWICK USA from 1994 through 2000.
All five furnaces are 4000 pound per hour rotary retort furnaces outfitted with a quench system, as well as a hopper feeder, a batch burnish barrel, and a batch/continuous drum drier. The furnaces are showing their age after a quartercentury, so rather than nickel and dime the maintenance, the mint opted for a comprehensive refurbishment.
“Our Partner has plenty of coin to heat-treat, but they don’t have any to burn," commented Marcus Lord, managing director at SECO/WARWICK USA. "These waste-heat recovery and combustion efficiency upgrades are going to save them a mint while cutting carbon and NOx emissions nearly in half."

To reduce energy consumption, the Mint is replacing insulation, roof panels, and radiant tubes as well as upgrading the loading systems. More energy efficient burners are being installed, along with recuperators to preheat the combustion air, to improve energy efficiency and use less natural gas. Mechanical improvements include replacing drive motors and two-speed gear boxes. The retort can over-heat and warp if the rotary retort unexpectedly stops before the cool-down cycle. As a failsafe, SECO/WARWICK added a pneumatic backup motor that can run the gear box off the Mint’s compressed air reservoir during a power outage.
The mint was established by the Coinage Act of 1792, when Philadelphia was the nation’s capital. It was the first public building constructed under the direction of the recently formed United States government. The machinery was powered by a horse walking circles in the basement.

A manufacturer is expanding their heat treat capacities with a new box furnace, designed for air atmosphere applications, from a North American furnace provider.
Lindberg/MPH's heat treat furnace has a maximum temperature rating of 1,250°F and a load capacity of 6,000 lbs and is designed to accept fixtures that are 48" wide by 84" deep by 48" high. A full-width roller hearth is located across the furnace chamber floor for manual loading and load support. Temperature is controlled by a Honeywell DC2500 Series controller with an adjustable alarm set-point and latching output relay; the controller disconnects the power to the heating elements and sounds an audible alarm in an event that temperature exceeds desired set-point.
“The high velocity forced heating system circulates heat evenly within the furnace chamber," commented Bill St. Thomas, business development manager at Lindberg/MPH. "[This] assures rapid and uniform heat transfer throughout the workload.”
