Rafael Advanced Defense Systems purchased a vacuum titanium casting furnace from SECO/WARWICK for UPC Precision Castings, an investment casting foundry in Israel. According to the furnace manufacturer, this is the first furnace of this type on the Israeli market. The single-chamber furnace is equipped with a hot (ceramic) and cold (copper) crucible. Melting processes of up to 40 kg of superalloys, mainly nickel-based, can be carried out in the ceramic crucible. The copper crucible melts 10 kg of titanium at a time. The furnace’s three-stage vacuum system allows it to obtain high vacuum in the range of 10-5 mbar. The solution is also equipped with a mold heater.
Tech Castings LLC, a supplier of superalloy investment castings to the commercial and military gas turbine engine markets, initiated a $4.5 million expansion at its Shirley, Ind., manufacturing facility. As part of the expansion, Tech Castings ordered a 100-pound vacuum precision investment-casting furnace from Consarc Corp. of Rancocas, N.J. The order includes start-up and installation, and delivery is scheduled before the end of 2022. The furnace is equipped with high-vacuum capabilities, state-of-the-art controls and increased automation. When completed, the expansion will more than double Tech Castings’ current capacity of components for the aerospace industry.
Armil CFS Inc. shipped a hydraulic pusher furnace designed to burn out and preheat investment-casting molds to a Midwest manufacturer of marine propulsion components. The furnace, which includes an automated tray extraction system and return conveyor, is designed to push a 48-inch-wide tray holding investment-casting molds up to 18 inches high. The combustion system is configured to promote clean firing of ceramic molds at temperatures up to 2150°F (1177°C).
Armil CFS Inc. shipped a natural-gas-fired pusher furnace to a European manufacturer of investment castings for the medical industry. The two-row, high-production furnace will be used for the burnout and preheating of investment casting molds. It has an operating temperature range of 1650-2100°F (900-1150°C). Residual wax will be consumed within the furnace chamber, eliminating the need for an afterburner. A recuperative combustion system will utilize a series of medium-velocity burners and a cross-flow recuperator operating in three zones of control.
