CoreTech introduces enhanced software

Taiwanese firm CoreTech System (Moldex3D), the True 3D CAE simulation solution provider, has released Moldex3D R12.0, a design validation and optimisation software for injection moulding simulation. It has several enhancements on troubleshooting capabilities, analysis accuracy, user friendliness and calculation efficiency, says the Hsinchu-based firm.

Moldex3D has been a plastic simulation standard in the automotive, digital electronics, medical and consumer products. To prevent defects or warpage on plastics, Moldex3D assists in visualising the melt flow behaviour injected into a mould cavity and predicts potential moulding problems upfront.

The latest version R12.0 supports more special shaped gates, runners, and runner ends, such as cashew gate with arc geometry, tapered ejector pins, or lock pin design. The enhancements on mesh quality and density allow users to build more realistic 3D mesh of complicated runner systems. It also supports the auto re-meshing capability when a gate location changes, thereby avoiding repeated re-meshing work on a cavity. Additionally, users now can directly import a CAD model in Parasolid format.

The R12.0 also introduces the industrial geometry healing technology developed by Elysium. A CADdoctor, it enables multi-CAD data exchange, geometry simplification and verification. When users generate Boundary Layer Mesh (BLM), they can automatically check and fix poor-quality geometry.

Furthermore, the software has an 80% increase in the computing speed of the filling analysis while the computation time for a model with 1 million elements will be shortened by nearly 50%.

Troubleshooting capabilities are reinforced in the solver kernels, such as flow behaviour visualisation, cooling optimisation, fibre orientation, stress evaluation, injection compression moulding simulation and encapsulation moulding simulation. It also supports advanced venting analysis, fibre breakage prediction and annealing analysis. The venting analysis provides trapped air temperature and pressure results to help users maintain mechanical strength and evaluate the quality of welding lines. In the fibre analysis, users can quickly check if the high shear stress inside the cavity or near the gates will cause fibre breakage and damage the strength of a part.

Users can also simulate the post-moulding annealing process in order to prevent deformation and stress cracking on a part. The simulation solution can be applied to compression moulding, powder injection moulding and multi-component moulding.
