Vacuum Casting technology is using master (SLA, SLS prototype, sample, CNC mock up) produce Silicon  tooling in vacuum condition, pouring by PU material in vacuum condition,Clone the same product from the mater accordingly. Vacuum Casting technology can be applied to change the material of the master, assembly prototype or small batch production, etc, in order to meet the needs of: performance testing from the process of product development, inspection and approval and marketing promote etc. 

Advantages: 

1 can produce small batch production 

2, change the material of product prototypes 

3 can add pigment color for processing 

Faults:

molding is complicated.
