We offer the best product range of Vacuum Casting MachinesTVCS and Pressure over Vacuum Casting Machine.
TVCs are fully automatic, robust, easy to use pressure over vacuum casting machines designed for small and medium casting laboratories.
This family of machines work with the well known pressure over vacuum concept, thus preferring the perforated flask against the solid ones. Melting is achieved in protective atmosphere (Nitrogen, Argon or Helium) while a strong vacuum pump is provided in order to boost the suction effect into the mould. As soon as the metal has entered the mould a strong compression takes place on top of the tree to reduce shrinkage porosity.
Flask size can reach up to 300mm in height and 160mm in diameter. Crucible graphite consumption is greatly reduced thanks to the gaswash procedure which removes the oxygen in few seconds from the charge loading operation. The machine is fully automatic making the operator’s job very easy (you simply have to load the alloy and flask and then press the START button). This will give you the most consistent result flask to flask.
And remember, meanwhile the machine is running the cycle, you can do other important jobs in your factory. Having a consistent, robust and easy to use machine in your factory is the key factor for a reliable casting production.

TVCd is the pressure over vacuum casting machine designed to meet the more severe needs in lost wax casting production.
This machine works with a new, revolutionary double chamber concept. This innovative system gives several advantages compared with the traditional single chamber suction system currently available in the market.
In TVCd melting chamber and flask chamber are completely indipendent and at the moment of casting the machine can control the metal injection into the mold by applying a differential pressure during pouring.
This yields to a faster injection compared to the simply gravity pouring with the benefit to cast items at lower temperature. This will result in better surface finishing of the cast parts.
The casting cycle takes only few minutes and, while the previous flask is cooling down in protective gas for no oxidation, the next charge can be loaded into the crucible and melted, thus overlapping two cycles for no time waste.
The machine is fully automatic having also a PC based monitoring system for process parameters acquisition and production data management with easy editing of casting programs suitable for many kind of alloy (optional).
This revolutionary machine is the synthesis of the most advanced engineering and years of experience in casting that only TOPCAST will bring in your factory.
