Injection molding liquid silicone rubber (LSR) is a kind of addition molding liquid silicone rubber. It takes advantage of its low viscosity (it has a certain fluidity and amorphousness before vulcanization) and is convenient for feeding by metering and mixing equipment. The special injection molding equipment automatically feeds, mixes, and molds the two components, and then quickly vulcanizes them to form products.

The injection molding process has gradually replaced the traditional molding process and has many advantages:

1. The liquid injection molding process is used for vulcanization molding, with accurate measurement and less material waste;
2. The vulcanization temperature is low, the cycle of molding products is short, and the production cost is reduced;
3. The product has high precision and can process complex shape products; there is no by-product in the vulcanization process, and no two-stage vulcanization is required;
4. The product has the characteristics of excellent aging resistance, weather resistance, non-toxicity, high transparency, high mechanical strength and good elasticity.

Therefore, liquid injection molding silicone rubber has become the preferred material in the fields of daily rubber products such as baby products, daily products, electrical insulation material processing, and cabinet accessories manufacturing, and is one of the fastest growing products in silicone rubber.
