MPI/WARP Prediction of part shrinkage and warpage
MPI/WARP Predicts and controls the shrinkage and warpage of plastic parts, ensuring parts are fit for purpose. DESIGN SOLUTIONS
What does MPI/Warp do ? § Determine part shrinkage and warpage based upon filling and cooling process § Identify cause of warpage usingle variate and sensitivity analyses § Differential Cooling § Molecular / Fiber Orientation § Material Shrinkage § Single or multi-cavity molds DESIGN SOLUTIONS
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 DESIGN SOLUTIONS
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 DESIGN SOLUTIONS
Small Displacement Analysis § Predicts the deformed shape if the part is unlikely to buckle § Fast algorithm is a benefit for iterative design/solution DESIGN SOLUTIONS
Large Deflection Analysis § Predicts the deformed shape after buckling § Load or Displacement control DESIGN SOLUTIONS
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 DESIGN SOLUTIONS
