Silicone injection molding is a manufacturing process that involves the precise shaping of heated Silicone or liquid silicone rubber (LSR) into various parts and products via an injection-molding machine. The process is highly efficient and preferred for mass production of complex, high-tolerance silicone parts, owing to silicone's flexibility, durability, and ability to withstand extreme temperatures. used to create a variety of products ranging from automotive parts, household appliances, to medical devices, among others. 

Types of Silicone Molding

There are four primary types of rubber moulding processes. They include:Liquid Silicone Rubber Injection Molding (LSR)/High Consistency Rubber (HCR) Silicone Molding/ Overmolding and Insert Molding,Each type of mold has unique features that make it suitable for specific applications.

1.High Consistency Rubber (HCR) Silicone Molding/Compression Molding

Compression molds are used to create simple rubber products that require minimal detail. The process involves placing uncured rubber material in a mold and then using heat and pressure to cure the rubber. The heat and pressure applied to the mold are used to create the desired shape and texture of the rubber product.

Compression molds are commonly used in the production of rubber gaskets, seals, and other simple products. The molds are made of high-quality steel, which ensures that the molds are durable and can withstand the high heat and pressure required during the molding process.

2.Liquid Silicone Rubber Injection Molding (LSR)/Injection Molding

Injection molding is similar to compression molding, but instead of pre-measured rubber material, a liquid or semi-liquid rubber compound is used. The compound is injected into the mold cavity under high pressure and allowed to cure. Injection molding is a highly automated process and is used to produce large quantities of rubber products quickly.

3.Overmolding and Insert Molding

Overmolding is a hybrid of compression and injection molding. In transfer molding, the insert (rubber or metal or plastic) is first placed into a chamber, The silicone or liquid silicone rubber is molded directly onto or around the base material, creating a multi-material, integrated part.
Overmolding provides several benefits, such as improved grip, cushioning, insulation, and aesthetics. It enhances the overall functionality, comfort, and appearance of the final product. Common applications of overmolding include handles, grips, buttons, seals, and medical devices.
