Bi-material injection Bi-material injection or bi-injection is a method for the economical production of parts combining the characteristics of two different thermoplastic materials The main applications are: Parts with 2 colors or having a transparent portion and an opaque portion. Parts with rigid zones and areas with ELASTOMERIC FLEXIBILITY: SEAL, SEAL, HINGE effects, areas with SHOCK absorbers, integrated push button function etc.) Rigid parts with areas a "SOFT TOUCH" or indeed "GRIP" The technology used by OPS Plastique is suitable for small and medium series. It reduces the cost of molds and thus makes this technology affordable to many new markets. The fleet of presses is adapted to this technology with presses from 50 to 250 tons.
