LSR Engineering is a specialized custom molder of Liquid Silicone Rubber.

LSR Engineering is a specialized custom molder of Liquid Silicone Rubber. LSR Engineering focuses on demanding applications that require high temperature plastic materials and very close tolerance molding.

LSR is a proprietary name for a range of two-component Liquid Silicone Rubbers used to produce elastomer parts via injection molding. Working closely with our Built-Rite Tool & Die division we produce precision molds for applications requiring high cavitation, Insert Molding/Over Molding of plastic and metal parts and low cavitation/prototype parts.

Because of its high thermal stability, resistance to compressive set and chemical resistance to aging, LSR is the material of choice... (more)
