Understanding LSR Molding
What is LSR (Liquid Silicone Rubber) Molding?
Liquid Silicone Rubber (LSR) molding is a state-of-the-art production process for creating intricate and durable silicone components used in various industries. Unlike traditional silicone rubber, LSR is a two-part system that is liquid at room temperature and cures upon heating. The process involves injecting the two parts—in a specific ratio—into a mold to form the desired shape. This method is highly automated, which minimizes human error and enhances consistency in product quality. LSR is particularly noted for its excellent chemical resistance, thermal stability, and flexibility, making it a preferred choice for applications ranging from automotive components to consumer electronics.
