Presentation Transcript

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

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

  3. 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

  4. MPI/Co-Injection

  5. 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

  6. 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
