Solar Atmospheres of Western PA acquired a used external-quench vacuum furnace at an auction in Philadelphia, Pa. The main objective of this purchase was to retrofit the furnace with a new hot zone and pumping technology that will help minimize and target the condensation of detrimental binders evaporating out of MIM parts. Solar Manufacturing designed the technology and the apparatus needed to consolidate the binders into one central location, thus minimizing the cleaning downtime staff was experiencing. This includes a completely new hot zone, a binder pumping port and a second vacuum pump. The collaborative effort ensured both projects came together seamlessly.
SECO/VACUUM, a SECO/WARWICK Group brand, sold a vacuum aluminum brazing (VAB) furnace to an international aircraft component supplier. The furnace is designed to meet tight temperature tolerances of +/-3°C and incorporates a high-vacuum system with diffusion pump. The VAB furnace is equipped with six temperature control zones and can accommodate loads with dimensions up to 36 inches wide x 28 inches high x 48 inches deep (900 x 700 x 1,200 mm). Delivery is scheduled for early 2022.
Centorr Vacuum Industries received orders for six high-vacuum furnaces for the precision processing of metals in heat treating, annealing and brazing applications. With sizes from 12 x 12 x 24 inches to over 48 x 48 x 48 inches and from 1 cubic foot to over 100 cubic feet, Centorr’s Workhorse furnaces can handle a variety of customer loads in either high vacuum or partial pressures of inert gas. The furnace design has a refractory-metal hot zone and high-vacuum pumping system for the processing of advanced materials requiring an extremely clean high-vacuum environment.
SECO/WARWICK Group delivered multiple shipments of metal heat-treatment equipment to South America. The primary customers for this equipment are Brazilian commercial heat treaters. So far this year, SECO/WARWICK has shipped equipment to three heat-treating plants in Brazil. Most recently, a vacuum furnace was delivered to Supertrat in Santa Bárbara D’Oeste. The furnace has a workspace measuring 600 x 600 x 900 mm (23.5 x 23.5 x 35.5 inches), and it will streamline and improve the capacity of the heat treater’s processes.
Mercury Marine of Fond du Lac, Wis., launched a plan to upgrade its heat-treating capabilities with a move to low-pressure carburization and high-pressure gas quenching. Partnering with ECM Technologies, the plan incorporates completely automated Nano vacuum heat-treating systems, which incorporate 20-bar nitrogen gas quenching with low-pressure carburizing (LPC). The Nano will operate several different carburizing hardening, and spheroidizing processes simultaneously. This change is a departure from Mercury’s traditional atmospheric carburization and oil quench system.
Aerojet Rocketdyne finished a major expansion of its Los Angeles facility to support production of new-generation RS-25 main engines for NASA’s Space Launch System (SLS), which will send astronauts to the Moon as early as 2024. The $59 million expansion includes renovations to existing buildings, the addition of additive-manufacturing (3D-printing) capabilities and new testing and storage facilities. New equipment includes a horizontal vacuum furnace for brazing exotic engine materials, four selective laser melting machines for additive manufacturing and nondestructive inspection equipment.
