Hasung Precious Metals Equipment Advantages
Hasung VCT series vacuum pressure casting machines reach from small to large capacities, from semi-automatic systems to solutions for a fully automatic casting production. A lot of special features enable you to optimize each casting according to its individual characteristics.
1. Gas Wash Procedure
. Crucible loading operation creates oxygen
. The Gas Wash procedure removes the oxygen in a fast and efficient way then refills back the chambers with argon or nitrogen.
2. Melting
. Advanced and accurate temperature control for the melted alloys.
. Medium frequency induction heating stirs the melted alloy and leads to a perfect homogeneity.
. Melting in an inert gas environment, the oxidation loss of the carbon mold is almost negligible.
3. Injection and Compression
. VCT has the unique feature to have the injection rate controllable and programmable for the timer.
. The metal enters smoothly inside the plaster mould. Then, a strong compresion takes place on the tree after filling and during solification phase.
4. This equipment uses Germany Siemens PLC program control system, Festo pneumatic valve and AirTec compoents, Taiwan Weinview touch screen, Germany Schneider, Japan Shinko, Japan SHAKO, Japan SMC, Germany SLGPC, and other foreign brand components.
Automatic vacuum and overpressure in the upper melting chamber and down flask chamber
When switch on "Cast", Vacuum and inert gas in the melting chamber provides the degassing of the alloy and avoids undesired oxidation during melting. Vacuum in the down flask chamber during casting improves the form filling when casting filigree parts and avoids air inclusions. Before metal pouring, vacuum and inert flowing into down flask chamber for cleaning which guarantees smooth casting metals.
