LSR (Liquid Silicone Rubber) tools typically have fewer cavities and higher upfront costs compared to tools for HCR (High Consistency Rubber), but what are the other considerations for this process versus compression molding?

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.

Overmolding is a specialized manufacturing process that results in a seamless combination of multiple materials into a single part. Some overmolded seals use a physical bond, while others require a chemical bond. For overmolded seals that require a chemical bond, specialized adhesive coatings are often used due to several key reasons.

Compression transfer molding and compression molding are related processes, but they are not the same. However, compression transfer molding can be considered a variation of compression molding with some key differences. Let's clarify the distinctions between these two processes, and watch a video that shows our compression transfer molding process in action.

GM tasked Morgan Polymer Seals to collaborate with ITW to design a mechanical seal for a new capless refueling system in the Cadillac CT6. The custom seal system had to reduce hydrocarbon emissions, seal on the fuel fill-nozzle, and remain flexible at a temperature down to -40°C. This article looks at the design process and how successful seal design is achieved for an automotive application.
