Injection molding of 2 thermoplastic polymers MPI/CO-INJECTION Injection molding of 2 thermoplastic polymers

MPI/CO-INJECTION Predicts the injection molding of 2 thermoplastic polymers, and their distribution through the part thickness.

What does MPI/Co-Injection do ? Optimize Filling and Packing conditions of 2 co-injected polymers Predict penetration of core material Predict thickness of skin material Determine the transition time for material change Optimize material usage Refine Part and Runner System design

MPI/Co-Injection

MPI/Co-Injection - Benefits Time to Market part fills correctly first time less mold trials Part Quality identify and minimize molding problems Cost Savings efficient production

Key Issues Addressed Will the Part fill ? When to set the transition point of material change too early - core material ‘bleeds through’ skin too late - inefficient use of core material Speed of Injection Optimal use of materials
