Fast Prototyping of Vacuum Casting

Vacuum Casting (Silicon Molding) is widely process used in rapid prototype making.And it’s one of the best way for low volume manufacturing of plastic and rubber parts. Using silicon mould instead of steel mould, the cost will be reduced. Usually one silicone mold can cast about 10 to 20 pieces of parts, depending on complexity, painting or original color, size and other factors of different parts. This process way is suitable for low volume production.


The process starting from a model obtained through CNC machining or SLA or SLS or others(or the model provide by clients), and placing a two piece silicone mold in a vacuum chamber.
