TAV Vacuum Furnaces manufactured a customized vacuum furnace for a research center in the nuclear field. The furnace, which has useful dimensions of 13.8 inches (350 mm) wide x 15.7 (400 mm) inches high x 13.8 (350 mm) inches long, has a maximum temperature rating of 3992°F (2200°C). It represents a solution for advanced ceramics and metallic parts already realized with the additive-manufacturing process. The goal of this project was to create a laboratory furnace using the standards normally applied in the industrial field.
The construction site for Solar Manufacturing’s new facility in Sellersville, Pa., is well under way. The new 57,500-square-foot building is dedicated to vacuum furnace manufacturing. Four bridge cranes are in place, the full plant and office roof is complete, and most of the concrete floor has been poured.
StandardAero Component Services dedicated a 30,000-square-foot expansion of its component repair facility in Miami, Fla. The additional working space and capital improvements included the installation of a vacuum furnace, state-of-the-art clean line and water-jet cleaning capabilities. According to StandardAero, the facility will now be the largest provider of aerospace and aerospace-derivative combustor overhauls in North America and the second largest in the world.
When large industrial vacuum brazing furnaces begin to produce customer parts that show discoloration instead of a pristine stainless steel finish or joints where the brazing material has refused to flow properly, production is quickly halted. Easy-to-find-and-fix leaks can take the furnace down for a half of a day, and more downtime is likely.
SECO/VACUUM Technologies supplied a precision gas nitriding vacuum furnace to a large North American heat treater. The horizontal, front-loading furnace is designed specifically for precision gas nitriding, ferritic nitrocarburizing and post-oxidation in a retort-style furnace with vacuum purge. The ZeroFlow furnace complements a prior SECO/WARWICK gas nitriding furnace already in production at the facility.
TAV Vacuum Furnaces shipped a vacuum furnace that offers an advanced solution for aluminide coatings of aerospace engine and industrial gas turbine components. The furnace has dimensions of 39.5 inches (1,000 mm) in diameter x 39.5 inches (1,000 mm) high and a maximum operating temperature of 2102°F (1150°C). Parts are placed inside the loading fixture, which is positioned, with an overhead crane, on the base supports. A retort is then placed on the base, evacuated and then flushed with inert gas to obtain a clean, pollution-free environment. The retort is transferred inside the furnace, where it is heated up to the process temperature.
Zenith Cutter, a manufacturing company based in Loves Park, Ill., purchased an Ipsen TITAN H6 vacuum furnace with 2-bar gas quenching that will be used at its Metkraft facility in Ho Chi Minh City, Vietnam. The furnace has a graphite work zone measuring 36 x 48 x 36 inches with a 3,000-pound load capacity. It is capable of operating at temperatures of 1000-2400°F (538-1315°C) with ±10°F (±6°C) temperature uniformity. The furnace is also equipped with a closed-loop water system and Ipsen’s PdMetrics predictive-maintenance software.
