Silicone/LSR (Liquid Silicone Rubber) injection molding is a manufacturing process used to produce parts and components from silicone or LSR materials. It is a highly versatile and efficient method for creating complex, precise, and durable silicone products. The process involves injecting liquid silicone rubber into a mold cavity, where it is cured to form the desired shape.
Silicone/LSR injection molding offers several advantages, including high precision, excellent chemical resistance, durability, and the ability to produce complex geometries. It is commonly used in various industries, such as medical, automotive, electronics, and consumer goods, to create a wide range of products, including seals, gaskets, medical devices, and more. This process is particularly suitable for applications where flexibility, heat resistance, and biocompatibility are essential.
