Challenges in compression molding can be solved with Moldex3D


You are looking for a simple manufacturing process that cost-effectively generates little waste during the molding process and is still suitable for large components? Then compression molding could be the solution. Let's take a look at how a simulation with Moldex3D can susuccessfully support you.

Compression molding includes a wide range of technologies, including thermoplastics, elastomers and thermosets. This variety of materials in turn includes bulk molding compound (BMC), sheet molding compound (SMC), and therwith thismoplastic granules and sheets. It is used for various applications such as automotive, medical devices and electrical connectors.

Simulation of compression molding features some special challenges. These include the calculation of the initial deformation of the batch. The 2020 and 2021 versions of Moldex3D offer some significant advantages for compression molding simulation. The advantages include modeling of plastic-elastic material behavior and anisotropic filler orientation behavior. The simulation can help in determining wall thickness and batch placement and sizing. It can also help users analyze the effects of process conditions and design revisions, as well as identify the critical problems. It increases product quality, reduces production costs, and shortens product development time. Moldex3D enables simulation of compression molding whilst fully considering all process conditions. It is possible to visualize the dynamic behavior of the compression in order to obtain a better evaluation of the compression properties. The results obtained include melt flow, pressure distribution, fiber orientation and warpage for both thermoplastic and thermoset materials.

Furthermore, it is possible to perform an integrated analysis between Moldex3D and LS-DYNA. In such cases, the main deformation is calculated in LS-DYNA up to a certain level, then the deformation from the first step is used as a batch for the Moldex3D simulation.
