Vacuum Casting Machine

Double Chamber

TVC-d is the only Pressure over Vacuum Casting Machine available in the market conceived in a double chamber topology. This unique characteristic is particularly suitable for lost-wax investment casting in jewellery, industrial prototyping and dental alloys. It melts metals as gold, silver, copper, aluminum, brass, bronze and pewter. For its peculiar features this family of machines are characterized of a very high productivity and the highest casting quality today available in the market. Casting cycle consists of melting the alloys in protective gas and then injecting the molten metal in the vacuumed flask. After the filling and during the solidification phase a strong compression takes place in the mould.

Single Chamber

TVC-s series machines are low-cost vacuum casting machines for lost-wax investment casting of jewellery and more generally: gold, silver and copper alloys. Casting cycle consists of melting the alloys in protective gas and then injecting the molten metal in the vacuumed flask. The heating system is a medium frequency induction generator ensuring excellent stirring of the alloy, while the temperature is accurately measured by a calibrated thermocouple. Process environment is conceptually divided in two parts: the melting chamber and the flask chamber. The melting chamber accepts a cylindrical crucible in graphite with a hole in the bottom and a stopper rod which operates an open/close action. The lower chamber accepts the refractory flasks, receiving the molten alloy.
