Vacuum Pressure Casting Machine


Hasung induction vacuum casting machines are suitable to melt and cast precious metals. According to the model, they can cast and melt gold, Karat gold, silver, copper, alloy with TVC, VPC, VC series, also steel, platinum, palladium with MC series.

The basic idea of the Hasung vacuum pressure casting machines is to close the cover and start the heating up once the machine has been filled with metal material.

The temperature may be selected by hand.

The material is molten under protective gas (argon/nitrogen) to avoid oxidation. The melting procedure could be seen easily by the observing window. The crucible is placed centrally in the upper part of the air-tight closed aluminium chamber in the core of the induction spool. In the meantime the flask with the heated up casting form is placed in the lower part of the stainless steel vacuum chamber. The vacuum chamber is tilted and docked under the crucible. For the casting process the crucible is set under pressure and the flask under vacuum. The difference of pressure leads the liquid metal into the finest ramification of the form. The required pressure could be set from 0.1 Mpa to 0.3 Mpa.

The vacuum avoids bubbles and porosity.

Afterwards the vacuum chamber is opened and the flask could be taken out.

The TVC, VPC, VC series machines are equipped with a flask lift which pushes the flask towards the caster. This simplifies the removal of the flask.

The MC series machines are tilting vacuum casting type, with 90 degrees turning specially designed for high temperature metals casting. It has replaced centrifugal casting.
