Why simulate a blow molding 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.
• Obtain optimum thickness distribution on a final product via ideal thickness settings on the preform or parison.
• Obtain optimum thickness distribution on a final product via ideal temperature settings on the preform or parison.
• Design pre-distorted images for sleeve shrinkage process.

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.

    

• 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).
• More information is placed at the reference manual.
