Solar Atmospheres of California adds Airbus approval

Solar Atmospheres, Fontana, Calif., has announced that they are now Airbus approved for heat treating.

Frank Trujillo, director of Sales for Solar Atmospheres of California, stated that, “Many Airbus suppliers were in need of a heat treater in the West that could process parts, plates and bars in support of increased Airbus production rates. SCA is proud to be a partner on the Airbus Team!”

With our wide range of furnaces, we are capable of processing very small pieces or loads of 50,000 pounds and up to 24 feet in length. This approval will translate into improved lead-times and greater efficiencies for all Airbus suppliers that require heat treat services in the Western Region.

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.

Wisconsin Oven ships electrically heated horizontal quench system

Wisconsin Oven, East Troy, announced the shipment of an Electrically Heated Horizontal Quench System to a manufacturer of products for the automotive industry. This system will be used for the solution treatment of aluminum.

The maximum temperature for this horizontal quench furnace is 1200°F and interior chamber dimensions of 2′ wide x 2′ high x 2′ long. The system has the capacity to heat 450 pounds of aluminum parts and the steel basket within 60 minutes. Temperature uniformity of +/- 10°F at set points 850°F and 1050° F was verified with a nine point profile test prior to shipment.

This horizontal quench system provides a 15 second quench delay from when the door begins to open until the load is fully submerged in the tank. The quench is manual, where the operator pulls the load out of the oven and onto the quench elevator using a hook. The quench delay time is recorded and enforced using sensors to detect the start and end of the quench operation, and to stop the process if the quench delay time expires.

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.

One Minute Mentor: Gas nitriding equipment

Gas nitriding and nitrocarburizing can be processed in horizontal or vertical chamber furnaces with refractory insulation. However, to allow a quick change of the atmosphere and to avoid influences resulting from previous processes in the same furnace, retort furnaces are preferred.

To enable an acceptable production capacity, large vertical retort furnaces are used. The figure is a schematic sketch of a vertical retort furnace with a compensator for sealing against the atmosphere. Nowadays large horizontal retort furnaces are also used. Horizontal retort furnaces of different size and execution are preferred for nitrocarburizing processes. Similar to the vertical execution, a good circulation of the process gas is needed to get uniform results, which can be reached by the use of a muffle and a high circulation rate. Indirect cooling is performed with an external cooling fan, blowing cold air along the retort. Other designs allow direct cooling of the process gas with an external heat exchanger.

Seco/Warwick to supply a vacuum furnace specifically designed for the MRO industry

Seco/Warwick, Meadville, Pa., will supply a vacuum furnace specifically for the maintenance, repair, and operations (MRO) industry. The solution will be utilized for repair solutions for both complex aircraft engines and gas turbines for the energy industry in Hungary.

The furnace on order is a unique solution due to the effective size of the heating chamber. It has been adapted to the AeroSpace Power requirements and has a working area of 1300 x 1000 x 1500 mm. Thanks to this, the furnace can accommodate large components – mainly aircraft parts, as well as gas turbines for the energy sector.

The featured technology on order, in addition to non-standard dimensions, is designed to process work in the presence of two gases: argon (used for partial pressure) and nitrogen, which is used mainly in the cooling process.

Additionally, the furnace will be equipped with a dew point sensor for each of the gases. It is a system which solves one of heat treatment’s very critical operational requirements, which is to control the quality/purity of gas used during the process. Vector also features a partial pressure control system based on three gases (hydrogen, argon, and nitrogen) to help prevent evaporation and sublimation of alloying elements from the load surface during the vacuum heat treatment or vacuum brazing process.
