Abstract

In the article, we described the process and the data needed to create a material in Magma Soft database. We showed how we defined the process low-pressure polymer moulding in Magma Soft. With this definition we executed simulations. The goal was to find a parameters, which can help us simulate defects, result of incorrect dosage of chemical foaming agent in the molten material. We ended up having good results by redefining one of the material’s parameters. We also executed a real moulding processes, which we used for validating the results.
