  1. MPI/FLOW Thermoplastic Injection Molding

  2. MPI/FLOW Predicts the flow of plastic throughout the injection molding cycle to ensure acceptable quality parts that are designed for manufacture.

  3. What does MPI/Flow do ? • Optimize Filling and Packing conditions • mold and melt temperatures • fill time and injection profile • packing time and packing profile • Determine injection pressure and clamp force requirements • Locate weld lines and air traps • Optimize material usage • Refine Part and Runner System design

  4. Automatic Runner Balancing • Ensures all cavities fill ... • at the same time • at the same pressure • are produced with consistent dimensions • Hot and Cold runner systems • Multi-Cavity and Family molds • Valve gate sequencing for hot runner systems

  5. Automatic Gate Location • Determines the most suitable gate location based upon … • Processibility • Minimum pressure • Geometric resistance • Thickness • Determines the next most suitable gate location

  6. Molding Window Optimization • Determines optimum molding conditions based upon … • Part geometry • Injection location • Material • Surface finish • Injection pressure

  7. Design of Experiments • DOE Manager based upon • Mold temperature • Melt temperature • Injection time • Injection profile multiplier • Thickness multiplier • Packing time • Packing profile multiplier • Methods • Taguchi • Factorial

  8. MPI/Flow

  9. MPI/Flow 3D

  10. Synventive Dynamic Feed System • Melt delivery system • Provides independent real-time, closed-loop, process control at each gate in the mold • Up to 32 independent pressure profiles • Each hot drop/gate has its own pressure control profile • Filling & packing stages are under pressure control • There is no velocity control

  11. Dynamic Feed System

  12. MPI/Flow Benefits • Time to Market • part fills correctly first time • less mold trials • Part Quality • identify and minimise molding problems • define a wide processing window • Cost Savings • optimum use of material • reduced cycle times

  13. Key Issues Addressed • Will the Part fill ? • Under what processing conditions ? • Identify possible Part defects • weld lines, air traps, sink marks • What type of Feed System ? • gate location(s) • hot/cold runners

  14. Flow Solver Technology • Flow results can be used as input for: • Cool • Warp • Stress

  15. Supported Analyses
