TVC

TVC TVC is a vacuum induction melting furnace for "pressure over vacuum" lost-wax investment casting of jewellery, industrial prototyping and dental alloys. It melts metals as gold, silver, copper, aluminum, brass, bronze, pewter. The heating is provided by a medium frequency induction generator, to assure an optimal stirring of the alloys while the temperature is accurately measured by a thermocouple. The melting of the alloy takes place under inert atmosphere and, when the casting temperature is reached and the flask...

Detailed Product Description

TVC is a vacuum induction melting furnace for "pressure over vacuum" lost-wax investment casting of jewellery, industrial prototyping and dental alloys. It melts metals as gold, silver, copper, aluminum, brass, bronze, pewter. The heating is provided by a medium frequency induction generator, to assure an optimal stirring of the alloys while the temperature is accurately measured by a thermocouple. The melting of the alloy takes place under inert atmosphere and, when the casting temperature is reached and the flask vacuumed, the liquid alloy is injected into the refractory mould. After casting, the metal is compressed into the mould during the solidification phase. Process environment of the TVC vacuum casting machines, is divided in two parts: the melting chamber and the flask chamber, each one with separated vacuum / pressure control, in order to obtain different vacuum values when casting. This allows to take control of the injection speed and the following compression rate. The melting chamber accepts a cylindrical crucible of graphite in different sizes, according to the machine model, with an hole in the bottom and a stopper rod which operates an open/close action. The lower chamber accepts the refractory flask receiving the molten alloy. You may use either flanged or unflanged flasks, with holes or just a simple steel pipe. Operator panel is simple and intuitive and, for the control of the casting process, you need only three pushbuttons. To edit your 100 casting programs and monitor the process, a Touch-Screen with Synoptic Display is provided. The machine comes out with a number of programs already set and ready to be used for the most common alloys.
