Liquid Silicone Rubber Injection Molding

Liquid silicone rubber lsr is a family of materials commonly specified for gaskets seals and cushioning pads in portable communications data acquisition devices sensing instruments and rugged enclosures with demanding sealing requirements in outdoor conditions.

Liquid silicone rubber injection molding.

Injection molding of liquid silicone rubber lsr is the fastest growing segment of stockwell elastomerics molding operations. The liquid injection molding lim manufacturing process molds silicone rubber into a broad array of parts and products. Like a standard aluminum tool an lsr molding tool is fabricated using cnc machining to create a high temperature tool built to withstand the lsr molding process. Liquid silicone rubber is a high purity platinum cured silicone with low compression set great stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts where high quality is a must.

Lsr molding differs slightly from thermoplastic injection molding due to its flexibility. Liquid silicone rubber injection molding is a thermoset process that cools the material delivery system while heating the mold tool to cure silicone material into parts. Due to the thermosetting nature of the. The liquid silicone injection molding process is highly automated with short cycle times to reduce the silicone part price.

Liquid silicone rubber injection molding lsr is a non toxic heat resistant thermal stability highly resilient and flexible thermosetting material. While the traditional reaction injection molding rim process focuses on a pressurized impingement mixing process liquid injection molding is comprised of a mechanical mixing method that blends a two component compound together in a mold.
