Vacuum Silicone Casting

1.2 Overview of vacuum casting process. The process starts by placing a two-piece silicone mold in a vacuum chamber. The raw material is mixed and degassed

The process starts with making a mould by encapsulating a master model in two-part liquid silicone rubber. A vacuum is then applied to remove any trapped air

vacuum castings require an expensive mould as well as the resin for each moulding. Vacuum casting relies on the production of a precise silicone rubber mould
