What is silicone rubber compression molding?
Compression Molding is the oldest original production method for molding silicone rubber. It is ideal for low to medium production
volumes and is a particularly useful molding process for molding gaskets, seals, O-rings, and large, bulky parts. It is a widely used, efficient and economical production method for many products, particularly low production volumes of medium to large parts and higher-cost materials.
Silicone Rubber compression molding is a molding process that produces a usable rubber product. Silicone Rubber products are made from uncured rubber or elastomer. An elastomer is any material with sufficient resilience or memory for returning to its original shape in response to pressure or distortions. Silicone Rubber and elastomer can be derived from natural sources, although they are mostly synthetic, produced through highly controlled chemical processes. Rubber is an excellent material for situations that require a material to expand and return to its original shape.
Silicone Rubber compression molding creates molded silicone rubber parts by pressing a block of solid silicone rubber into a silicone rubber molding metal cavity. The silicone rubber is then exposed to heat, activating a chemical reaction. While there are variations in specific methods, all silicone rubber manufacturers use heat and pressure method to form molded silicone rubber products.

Silicone Rubber Compression Molding Steps:
1.) Uncured Silicone rubber is preformed to control weight, shape and specification
2.) Solid Silicone Rubber preform is placed into the mold cavity
3.) Solid Silicone Rubber molded is closed compressing the rubber to fill the mold’s cavities
4.) Mold remains closed under pressure and temperature to reach optimal cure
5.) Compressed Silicone rubber products are removed from the mold and the process is ready to begin again
