OVERVIEW:
LIM & LSR Molding

lim-lsrmold.jpg

Liquid silicone rubber (LSR) injection molding is a long established process but it is enjoying an upsurge in interest for medical, automotive, infant care, and general industrial applications. It requires specialty machinery and processing considerations compared to conventional thermoplastics molding. Notably, whereas thermoplastics must be heated in the injection barrel to their melting point, and then cooled in the mold back to a solid state, the reverse occurs with LSR. It starts out as a fluid and is then heated within the mold to initiate curing.
