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.
Hasung Automatic Vacuum Pressure Casting Machines compare to other companies
