What is Liquid Silicone Rubber Molding?

Liquid Silicone Rubber (LSR) molding is an injection molding process that uses liquid silicone material to produce flexible, durable, and high-precision components. The material is injected into a heated mold where it cures quickly, allowing for efficient and repeatable production.

This process is ideal for applications requiring tight tolerances, intricate geometries, and excellent material performance. LSR parts offer superior resistance to heat, chemicals, and environmental conditions, making them widely used in medical, automotive, electronics, and consumer products.
