SECO/VACUUM, a SECO/WARWICK Group company, received an order from an international electric-vehicle (EV) automaker for high-pressure gas-quenching (HPGQ) and nitriding furnaces for the heat treatment of large high-pressure casting dies used in the production of aluminum underbody components. SECO/VACUUM will supply two furnaces with work zones that can accommodate loads with dimensions up to 40 x 40 x 96 inches (1,000 x 1,000 x 2,400 mm) and weighing up to 7.5 metric tons.
Nitrex supplied a turnkey gas nitriding system to Ohio-based aluminum extrusion die manufacturer Youngstown Tool & Die (YTD) in the fourth quarter of 2020. The system adds Nitreg controlled nitriding to YTD’s range of heat-treating services. YTD relocated to a larger manufacturing facility in summer 2020 and made investments in new production and finishing equipment to increase its manufacturing capabilities and meet growing demand. As part of the new production, YTD installed a Nitrex pit-type nitriding system that has a 4,400-pound capacity for treating aluminum extrusion dies.
Bodycote announced the opening of a new heat-treatment facility in Elgin, Ill. The facility is now fully operational and supporting customer requirements. It continues to provide all of the processes and capabilities that were previously offered at Bodycote’s Melrose Park location. In addition, the Elgin facility offers nitriding, Corr-I-Dur, nitrocarburizing and low-pressure carburizing (LPC) to customers from the agricultural, mining, construction, automotive and other manufacturing supply chains in the upper Midwest region.
Alugen Aluminium, a Turkish aluminum extrusion company, expanded its production capabilities with a Nitrex NXK series nitriding system. The turnkey system was delivered with Nitreg potential-controlled gas nitriding and Nitreg-C potential-controlled gas nitrocarburizing technologies. Process recipes are optimized to improve the performance of aluminum extrusion dies and increase throughput. The service life of dies is also extended through periodic nitriding, which helps to control the high heat and impact pressure that dies undergo during extrusion cycles. With a work area of 23.5 x 47.25 inches (600 x 1,200 mm) and a load capacity of 1,700 pounds (800 kg), the NXK system allows Alugen to mix special dies with regular production dies for a faster turnaround of product-specific production plans.
Nitrex, a Novacap portfolio company and a global provider of fully integrated heat-treating solutions and technologies, unveiled a new corporate brand identity. A new logo will be adopted by all the Nitrex business units. For now, the names of the legal entities will not change so customers, suppliers and stakeholders can continue to use the existing names and addresses in all official communication. The new wordmark for United Process Controls leverages its well-known trade name, the UPC initials, in combination with the company’s best-known brand asset, Marathon Monitors, to form UPC-Marathon. G-M Enterprises, the newest addition to the Nitrex Turnkey Systems portfolio, traded its metallic graphic for a single-color wordmark using the same typeface as the other logos with the addition of the tagline, “A Nitrex Company.”
The nitriding process begins at the surface of the part with the formation of a compound (aka white) layer, which depends to a large extent on the composition of the steel (in particular, the carbon content).
Lindberg/MPH shipped a gas-fired nitriding pit furnace with built-in retort to a company in the welding industry. The furnace is designed for single- and two-stage nitriding processes and post-oxidation applications. The design accepts either one-piece work baskets, retort baffle or nest trays. The gross load capacity is 5,000 pounds at 1200°F, and the furnace chamber has dimensions of 38 inches in diameter and 90 inches high. The furnace is designed to produce laminar airflow to obtain the required +/-15°F temperature uniformity.
FA Krosno completed the installation of a Nitrex nitriding system at its manufacturing facility in southeastern Poland. The pit-type system has overall chamber dimensions of 86 inches (2,184 mm) in diameter x 136 inches (3,452 mm) high with a capacity to nitride an 8,400-pound (3,800-kg) load. The delivered solution includes Nitreg and ONC technologies. ONC is a post-nitriding oxidation process that further enhances the quality of the nitride layer, provides additional corrosion protection and similarly contributes to the aesthetic finish of piston rods. The system, which started production in December 2019, replaced a defunct gas nitrider that was phased out due to inconsistent results and high scrap losses.
