Software for coupling process and structure simulation for injection molded plastic components

converse analyse FEM

CONVERSE is an easy-to-use software which enables a coupling between CADMOULD and FEM programs for structural mechanical analysis. The consideration of the complex material behavior of plastics is thus possible with only a small additional effort.

Injection molding leads to a specific microstructure in the component, which in turn influences the mechanical properties of the finished part. Properties such as fiber orientation and residual stresses generally vary throughout the component. In addition, there is certain topological information, such as the position of weld lines, which can be critical for the component quality. It is therefore crucial to consider these effects in order to correctly assess the mechanical performance of the component.

In order to capture these influences, approximative approaches are often used in engineering practice. Since these do not necessarily reflect the actual behavior correctly, premature failure may occur. On the other hand, a conservative design increases the overall cost and weight of the component. By using CONVERSE, these problems are avoided because the accuracy of the FEM simulation is significantly increased so that the user can exploit the full potential of the component. In addition, assessments can be made for tool deformations such as core displacement or mechanical loads on inserts during the mold filling process. It is also possible to evaluate the thermal load of temperature-sensitive inserts.
