Liquid Silicone Rubber (LSR) generally has faster cycle times in molding processes than High-Consistency Rubber (HCR), but that doesn’t always make LSR the preferred choice for molding automotive gaskets and seals. In this article, we explore why LSR cycle times are typically faster, and how faster cycle times can help reduce manufacturing costs for some automotive programs.
