Simulation of biocomposites Biokunststoffe

Injection molding simulation for bioplastic

Realistic simulation of plastic components made from renewable resources

Plastics processors have long been looking for sustainable alternatives to conventional plastics. But when bioplastics are injection molded, they frequently display completely different behavior to their classic relatives. As the expert for plastics injection molding simulation, we are the first supplier to have extended its CADMOULD and VARIMOS software products to include the calculation of bioplastics and biocomposites, i.e. conventional polymers reinforced with natural fibers. With the simulation, users of these materials can now also benefit from the advantages of simulation and achieve savings of around 30 percent in both development and cycle times.

Shrinkage and Warpage with bioplastic

Influence of bioplastics in injection moulding processes

We participated in the “NFC Simulation” research project sponsored by the German Federal Ministry of Food, Agriculture and Consumer Protection (BMELV), with partners that included automotive manufacturer Ford. On the basis of a glove compartment assembly, we were able to show that our software realistically depicts the influences of the injection molding process, such as filling, packing pressure, shrinkage and warpage, right through to the transfer of the fiber orientation to the crash simulation. “Even the crash simulation at Ford supplied outstanding results with the fiber orientation delivered by CADMOULD”, says Simcon owner Dr. Paul Filz looking back over the project.

CADMOULD has also been successfully used for bioplastics in other areas, such as consumer electronics and musical instruments.
