Silicone Molding

Silicone Prototypes

Silicone Molding

Silicone prototypes can be molded using methods such as compression, transfer and injection molding. The molding method is chosen based on silicone part geometry, application requirements, and type of silicone material. Choosing the appropriate silicone molding method is critical as it affects the silicone prototype quality, process efficiency and also initial tooling costs & piece pricing. At Konark Silicones, an engineer will walk you through the silicon molding process to determine the appropriate method to ensure we use the optimal solution for your project.

Molding Method Description Start Finish
Compression Compression is possible for simple silicone part geometries. HCR or gum silicone material is weighed and placed on the hot mold. Mold is then compressed and the material begins curing in shape.
Transfer When the silicone part design is complex or involves cores, transfer molding is the choice. The material is placed in a cavity and when compressed, flows through a runner and gate into the part geometry.
Injection For medical grade silicone parts and high volume production, which require an extremely efficient process, liquid silicone rubber is pumped into an injection barrel. Material is then injected into the mold at high pressures.
