Silicone vacuum molding

Silicone vacuum molding, a technique employed in rapid prototyping and small - batch production, has several distinct characteristics.

It uses platinum - cured silicone rubber to create highly elastic and durable molds. These molds can precisely replicate intricate details, including fine textures and complex geometries.

The process is carried out under vacuum conditions. This helps to eliminate air bubbles, resulting in smooth surfaces and high - quality finishes.
