Silicon Mold, often called Vacuum Casting, is a manufacturing process used for rapid prototyping and low production runs. The silicone mold is usually applied in the new product development stage, and a small batch (20-30pcs) of samples’trial-manufacture.
The silicone mold with good toughness can manufacture the parts with complex structures, fine patterns, no or even negative draft angle. The mould manufacturing period is short while the products' quality is high .
We generally use the silicone rubber and the reactive polyurethane materials to make the silicone mold . It is a popular technology of rapid tooling manufacturing.
