Presentation Transcript

  1. MPI/WARP Prediction of part shrinkage and warpage

  2. MPI/WARP Predicts and controls the shrinkage and warpage of plastic parts, ensuring parts are fit for purpose.

  3. What does MPI/Warp do ? • Determine part shrinkage and warpage based upon filling and cooling process • Identify cause of warpage using single variate and sensitivity analyses • Differential Cooling • Molecular / Fiber Orientation • Material Shrinkage • Single or multi-cavity molds

  4. Residual Stress Analysis • Calculates Residual Stress from filling, packing • Visualize frozen-in stress through part thickness • Determine stress prior to and after ejection • Residual stress values used to calculate final part shape

  5. Linear Buckling Analysis • Predicts the likelihood of the part to buckle • Indicates the analysis type that should be used to determine final part shape • Small Displacement Analysis • Large Deflection Analysis

  6. Small Displacement Analysis • Predicts the deformed shape if the part is unlikely to buckle • Fast algorithm is a benefit for iterative design/solution

  7. Large Deflection Analysis • Predicts the deformed shape after buckling • Load or Displacement control

  8. Single Variate Analysis • Isolate and predict the contribution to part warpage of … • Differential Cooling • Molecular / Fiber Orientation • Material Shrinkage • Compatible with small displacement and large deflection analyses

  9. MPI/Warp

  10. MPI/Warp 3D

  11. Local Co-ordinate System

  12. Geometry Dependent XY plots

  13. MPI/WARP - Benefits • Time to Market • less mold trials • Part Quality • dimensional stability • accurate fit of mating components • appearance • Cost Savings • material choice • cycle time

  14. Key Issues Addressed • How much does the part warp ? • What is the cause of warpage ? • Do defelections fall within design tolerances ? • Will the part buckle ? • What is the cause of buckling ?

  15. Warp Solver Technology • Warp results can be used as input for: • Stress * • Warp can be used with: • Co-Injection * • Injection Compression * • Microchip Encapsulation * • Gas Injection * * (not 3D)

  16. Supported Analyses
