High-precision simulation of blow molding for highly designed cosmetic containers.
In the cosmetics industry, there is a demand for highly designed containers that catch the consumer's eye. In particular, complex shapes and thin-walled molding can easily become manufacturing challenges, potentially leading to an increase in the number of prototypes and costs. B-SIM supports a wide range of processes from direct blow to injection and stretch blow, contributing to solving these challenges by accurately reproducing time-dependent deformation using the K-BKZ model. The parison and preform shapes can be input using the B-SIM template, and can also be imported from Ansys and STL files. It accurately reproduces blow molding with a variety of settings, including clamp position, temperature of the parison and preform, thickness distribution, friction and heat transfer with the mold, timing of the blow, and direction of mold movement. 【Application Scenarios】 - Prototyping of highly designed containers - Optimization of thickness distribution in thin-walled molding - Prediction and countermeasures for molding defects 【Benefits of Implementation】 - Reduction in the number of prototypes - Cost reduction - Manufacturing of high-quality containers

basic information
**Features** - Import mold shapes from STL, DXF, Patran, and VRML files. - Material slip due to differences in mold materials is reproduced based on the friction coefficient. - The material model employs the integral-type viscoelastic models K-BKZ and Leonov. - Accurately simulates time dependence and large deformations, with high precision in reproducing sagging of sheets and parisons. - Physical property data for major materials is already registered, allowing for immediate analysis. - Three different damping functions that accommodate strain hardening. - Adopts the WLF temperature dependence model. - Achieves short computation times through a multi-threaded solver and batch analysis system compatible with 64-bit and parallel processors. - Displays detailed 3D color scale graphs of thickness, temperature, stress, and elongation after molding, as well as arbitrary cut lines. - Predicts molding defects and their risks through contact conditions between the mold and sheet, highlighting large deformations of the sheet, and weight calculation functions for arbitrary parts. - Analysis results can be exported to Ansys, IGES, DXF, Cosmos/M, Patran, and LS-Dyna files for structural analysis.
