Wisconsin Oven ships draw batch oven to the military

Wisconsin Oven Corp., East Troy, Wisconsin, announced the shipment of an Electrically Heated Standard Draw Batch Oven (SDB Series) to a United States Military Base. The industrial oven will be used for heat treating aerospace components and features combination-style airflow delivering both horizontal and vertical upward flow for optimal heating rates and consistent temperature distribution. Temperature uniformity of ±5°F was verified at set points of 200°F, 700°F, and 1200°F in accordance with a Class 1 Temperature Uniformity Survey per AMS 2750H. The oven incorporates CAN-style construction with a heavy plate exterior and 6 inches of high-temperature industrial insulation, a 15,000 CFM recirculation system with variable frequency drive, and a UL508A-certified control panel.

Lindberg/MPH ships aluminum melting and holding furnace

Lindberg/MPH, Mich., has announced the shipment of a gas-fired reverberatory aluminum melting and holding furnace equipped with a preheat hearth. The furnace, designed for manufacturing aluminum parts, boasts a melt rate of 10,000 pounds per hour and a maximum temperature rating of 1450°F. It has a holding capacity of 85,000 pounds, based on 155 pounds per cubic foot of molten aluminum.

The furnace features a vertically rising air-operated door for loading the preheat hearth and a full-width cleanout door at the rear for unloading. Designed with an elevated base, it includes a bottom-mounted magnetic stirring mechanism and an air pressure pump well for dispensing molten aluminum. This configuration allows the furnace to remain idle for extended periods without significant temperature variation.

Temperature control is managed by three controllers, while flame supervision equipment ensures safety, including forced-air purging and automatic shutdown in case of system failures.

Nitrex installs nitriding system at Akademi Metalurji

Nitrex Vacuum, Quebec, has installed a turnkey nitriding system at Akademi Metalurji, a full-service commercial heat-treating solutions provider located in Turkey. The project includes a mid-sized pit-type furnace, advanced controls, three process technologies along with accelerated cooling. 

The decision to invest in a new nitriding system was driven by the company’s objective to overcome efficiency and quality challenges faced with their previous furnace at the Gebze facility. The prior system consumed excessive amounts of process gases and yielded inconsistent nitriding results. With the addition of a Nitrex NX-1015 pit furnace, Akademi Metalurji can now save on process gases and production time, while also expanding their heat treatment capabilities to accommodate wider-dimensioned parts. The nitriding furnace offers an effective work zone of 39” diameter by 59” high (1000 x 1500 mm) and can handle a load of up to 4400 lbs. (2000 kg). The supplied library of Nitreg-based recipes is tailored to meet different application requirements, resulting in a hardened surface that is highly wear-resistant. For applications like machinery components, tooling, dies, and molds, where Akademi Metalurji specializes, Nitreg delivers improved tooling performance, ensuring longer service life and higher throughput. Ultimately, this leads to tool cost savings for their customers.

The system was successfully installed at the Gebze facility, located southeast of Istanbul, and commenced operations in April 2023. Since then, it has been running smoothly, delivering excellent results.

Quintus Technologies supplies high pressure Flexform press to airframe manufacturer

Quintus Technologies, Vasteras, Sweden, announced that they will supply a high pressure fluid cell press to France’s LAUAK Group, a Tier 1 supplier to the aerospace industry. The press will be installed at the LAUAK Aerostructures factory in Grandola, Portugal, in September 2023. 

Reaffirming its continued commitment to productivity enhancement, LAUAK selected the Quintus model QFC 0.7×1.8-800 press with high pressure technology to bolster its manufacturing efficiency. “The forming press is undoubtedly at the heart of sheet metal production,” says Mikel Charritton, LAUAK Group Managing Director. “Especially in the context of the current aerospace ramp-up, in particular the A320, A350, and B737 programs, LAUAK’s capital equipment investments are strongly influenced by the imperatives of competitiveness. This press significantly increases and secures our production capacity.” Quintus’s proprietary hydroforming process requires only one rigid tool half, an innovation that not only generates significant tool cost savings but also eliminates several forming operations, intermediate heat treatments, and operator dependencies.
