B-SIM Simulation of blow molding and sleeve shrinkage

CAE.FEA.CFDadminClicks Comment
Features of B-SIM
 
Simulates extrusion blow molding from parison.
Simulates stretch blow molding from preform.
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, etc.
Imports general 3D molds from IGES format, VDA-FS via stereolithographic STL file and Patran Neutral file.
All molds movable (up to 10 tools can be used in one simulation project).
Time dependent parison sagging included.
Friction between stretched plastic material and plug.
Heat transfer between material / molds 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 B-SIM project for solver. Tight connection between initial project and result files.
Many typical blow molding problems solved and distributed on installation CD.
Material
 
B-SIM uses time dependent, viscoelastic K-BKZ model.
Data of frequently used polymers are available in the B-SIM material database.
Solver
 
Fast contact analysis.
Very fast iterative multithreaded solver gets use of parallel processing on PC with more than one processor.
Upper limit of sheet elements or mold elements is limited only by PC memory.
Solving a set of blow molding problems in a batch mode. This enables automatic case study solution.
Results
 
Investigate contact between plastic material and molds.
3D color maps of thickness, temperature, stress, extension, 3D cuts.
Easy refinement of the grid in 3D areas of interest from the post-processing window.
Export results for structural analysis to Ansys, IGES, DXF, Cosmos/M or Patran files.
Interactive thickness / temperature / position information with a simple mouse click.
Export animation file to Microsoft Video Player format.
Critical venting areas analysis.
Part weight calculation.
Cooling calculation.
Position tracking.
Pre-distortion of images & sleeve shrinkage process (option)
 
Prediction of printed image deformation, mainly for sleeve shrinkage process.
    Shrink sleeve process
B-SIM is able to pre-distort images for printing them on the flat sheet or preform, so that once shrinked, the images appear true.
Image projection manager enables to projects multiple images (planar, cylindrical, spherical projection).
IGES entities polyline, line and arc can be projected, distorted / predistorted and exported back to IGES file.
3D VRML models can be used too (especially for complicated 3D shapes with graphics, where common projection methods cannot work).
