Simulation
Computer-aided simulation offers the potential to optimize the entire development process of plastic products. This means that technical risks relating to process and product can also be identified at a very early stage and subsequent corrections and the necessary number of prototypes can be minimized. In this way, valuable time and costs can be saved with the help of simulations. Our state-of-the-art laboratories also have numerous options for determining material parameters specifically for your simulation.
Whether process or structural simulations, SKZ is happy to support you as a reliable partner in:
- Filling, shrinkage and warpage analysis
- Optimization of your component geometry, the gating system and mold temperature control
- Plastic-compatible component design
- Strength verification
- Material data determination for process and structure simulation
We are looking forward to your requirements.

Technical equipment
Software solutions
Autodesk Moldflow Insight is available to us for injection molding simulation for the calculation of complex components and tools. The material database includes more than 10,000 materials (thermoplastics, thermosets, elastomers).
With Moldex3D Professional we also have a powerful solution for the design and optimization of your injection molding process. With one of the leading 3D CAE software solutions, we offer a deep analytical view into the interior of the component and mold.
1D simulation of special extruders with software solutions specially developed by SKZ. Depending on material data and process parameters, important process variables such as pressure, filling level, residence time or degree of melting can be determined via a parameterized description of the extruder geometry.
Ansys Mechanical offers numerous possibilities at the component level. Among other things, we perform deformation and strength analyses, evaluate fatigue and long-term behavior, and calculate mechanical and material connections.

Converse builds a bridge between process and structural simulation. This means that a tool for integrative simulation is also available at SKZ. In this way, local influences (e.g. weld lines) or anisotropic material behavior in short-fiber-reinforced plastics can also be taken into account in the structure simulation.
