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.
Italy’s TAV Vacuum Furnaces received an order for a horizontal debinding and sintering vacuum furnace from a company focused on the design, development and production of braking systems. The furnace has useful dimensions of 31.5 inches wide x 31.5 inches high x 47.25 inches long (800 x 800 x 1,200 mm) with a maximum gross charge of 1,543 pounds (700 kg) and maximum operating temperature of 1022°F (550°C). It is equipped with a pumping unit, an AISI 310 retort for cycles up to 550°C and a forced-gas-circulation system. After pressing, the parts are placed inside the debinding furnace, where the binder is removed, pumped and trapped. Then the temperature is raised to carry out the sintering process. After a residence time at the maximum temperature, the heating is switched off and the retort is cooled.
ASM International and AGMA are committed to holding the 31st Heat Treating Society Conference and Exposition (Heat Treat 2021) and the Motion + Power Technology Expo September 14-16 in St. Louis, Mo., and will not be canceling the events. Members want a platform to conduct business face‐to‐face, and it is our job to support that with our conferences and trade shows. The top priority remains the health and safety of all those who support the event on‐site. We have protocols in place and are working with America's Center Convention Complex, the city of St. Louis and our vendor partners to provide a safe environment for a successful in‐person event.
Centorr Vacuum Industries, to satisfy multiple orders, is currently building two furnaces designed for the metal 3D-printing and metal injection molding (MIM) industries. Sintervac AM is designed for debinding and sintering. It is outfitted with a graphite hot zone and operates in vacuum, partial pressure or positive pressure of forming gas. It also has a dual trapping system to handle the process off-gassing from binder-jet 3D-manufactured parts. MIM-Vac, which has multi-zone temperature control for improved processing uniformity, has the ability to handle virtually any metal feedstock.
Busch (UK) Ltd., part of the global Busch Vacuum Solutions group, acquired Vacuum Furnace Engineering (VFE). The acquisition enables both VFE and Busch (UK) to strengthen their leading vacuum solutions and services for U.K. metallurgy and composites manufacturers. Since 1985, VFE has provided vacuum services, specialist equipment, control and calibration solutions to heat-treatment facilities and advanced material manufacturers in the U.K. Busch (UK) has 50 years of experience in providing individual and tailor-made vacuum solutions and services to companies in a wide range of market segments, including metallurgy.
Solar Atmospheres of Western PA successfully vacuum heat treated what it says is the largest and longest load of nickel-alloy tubing ever in a commercial vacuum furnace. The goal was to preserve the elements of brightness and cleanliness of the 45-foot-long seamless tubing while meeting stringent mechanical properties.
Solar Manufacturing Inc. of Sellersville, Pa., announces the receipt of US Patent No. 11053560 issue date July 6, 2021. The patent covers the use of a full isolation power transformer for use with a 600-HP, 460-volt motor and with an ionizing gas (such as argon) to prevent electric-motor ground fault and failure, with additional solid-state circuit protection, in conjunction with a vacuum furnace gas-quench system.
SECO/WARWICK will deliver a Vector vacuum furnace to the manufacturer of circulation and collection coins in Egypt. The National Mint of Egypt is the seventh mint in the world (others include Brazil, Canada, China, Poland and Turkey) to order a furnace from SECO/WARWICK. The Vector vacuum furnace with 15-bar high-pressure gas quenching is suited for the operating performance requirements of mints. It enables quick heat treatment with a working space that is optimum for circulating and collection coins, embossing dies, medals and special orders. The furnace will be used mainly for producing collection seals.
SECO/WARWICK will deliver two vacuum furnaces to Flansch-Tech, a specialist in aluminum and steel forging, in Budapest. According to SECO/WARWICK, one of the vacuum furnaces will be the largest in Hungary. The Vector with horizontal charge loading is equipped with a 15-bar nitrogen cooling gas-pressure system and a production work area of 900 mm wide x 900 mm high x 1,200 mm long). It will be used for the heat treatment of tool steels – mostly dedicated to hardening and tempering – and will allow Flansch-Tech to process larger parts.
