MPI/FLOW

MPI/FLOW predicts the flow of plastic throughout the injection molding cycle to optimize filling and packing conditions, determine injection pressure and clamp force requirements, locate weld lines and air traps, and refine part and runner system design. The tool enables time-to-market, improves part quality, and achieves cost savings.

  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
