IP ( Injection Press ) molding technology

SMART MOLDING - TOYO MACHINERY & METALProduct Information

IP Molding

A molding method where injected plastic material into the mold is pressed by the clamping mechanism of the molding machine IP molding
Motion picture showing IP molding * After clamping, the core base on the left side moves subtly, which is pressing motion.

Effects of IP molding

*Post-molding deformation is reduced as residual stress is released.
*Significantly improved transcription property
Effective moldings for IP molding: Light guide plates, cases and reels for memory medium
