T-SIM is a software package for simulation of thermoforming. T-SIM predicts the final wall thickness distribution based on the specified processing parameters (the pressure level, the speed of tools, the sheet temperature distribution etc.). T-SIM also can predict image distortion and pre-distortion.

Why Simulate a Thermoforming Process ?
• Reduce the design time for your products
• No need to perform expensive trial-and-error procedures
• Select an optimum design from many possible alternatives
• Get optimum thickness distribution on final product via temperature settings on the sheet
• Design pre-distorted images for in-mold decoration process

Features of T-SIM
• Simulates positive / negative forming with / without plug assistance
• Time dependent deformation is described by viscoelastic K-BKZ model
• Three different damping functions for a better material data fit (strain hardening)
• WLF temperature dependency
• Material database containing PE, PP, PET, PC, PMMA, ...
• Imports general 3D molds from IGES, VDA-FS via stereolithographic STL file, DXF or Patran Neutral file
• All molds movable (up to 10 tools can be used in one simulation project)
• Time dependent sheet sagging included
• Friction between stretched plastic material and tools
• Heat transfer between material / tools and material / air
• User-friendly setup of technological parameters with graphic
• Windows context sensitive help, tutorials and hands-on examples
• OpenGL included, allowing dynamic image rotation, zooming and panning. This enables fast shading or wireframes and contact visualization options.
• Easy, completely editable setup of T-SIM project for solver. Tight connection between initial project and result files.
• Many typical thermoforming problems solved and distributed as examples on installation CD
