Warp

Moldex3D Warp allows users to perform dynamic warpage analysis on thick parts and those parts that have extreme thickness changes. With Warp, users can easily validate part deforming ratio of shrinkage effect and efficiently identify warpage causes. For fiber-filled material, Warp incorporates fiber composite theories and fiber orientation results to predict its anisotropic shrinkage, residual stress, and material viscoelasticity effects on warpage. Furthermore, Warp can link through FEA Interface module, which integrated with most leading structure software to perform more realistic structural analysis.

 Capabilities

  • Evaluate final part shape before actual molding
  • Evaluate unbalanced cooling effect on warpage
  • Evaluate volumetric shrinkage effect on warpage
  • Evaluate in-mold constraint effect on warpage
  • Evaluate thermal-induced residual stress and moldbase thermal deformation effect
  • Provide flatness to evaluate the warpage of surface appearance

Features

Part warpage analysis

Part warpage analysis

Calculate final part shape due to material shrinkage as the temperature and pressure changes from the process settings to room conditions.

Residual stress analysis

Residual stress analysis

  • After part ejection, the part shrinks and deforms to an equilibrium shape. At this moment, the remaining stress inside the part is called process-induced residual stress
  • Calculate residual stresses developed during the entire molding cycle, including effects of temperature and pressure distributions, material orientation and geometric features

Material anisotropic analysis

  • Anisotropic properties are calculated based on the material orientation tensors obtained from flow analysis
  • Anisotropic properties are transferred to general structure CAE software for analyzing the part structure with process-induced effect

In-mold constraint effect analysis

  • Before the part is ejected, the deformation of warpage has been developed inside the mold. However, it cannot shrink and deform freely due to constraints by the rigid mold
  • Calculate the part warpage with in-mold constraint to enhance the analysis accuracy
