Cooling prediction for thick walled parts
Transparent thermoplastic materials, such as polycarbonate, are frequently used to manufacture thick-walled optical components, especially in LED lighting applications. Using the multilayer injection molding process, an optical component is manufactured in layers to achieve the final wall thickness. Simulation is essential to achieve quality and economic goals.
As leading supplier of polycarbonate materials, Covestro leverages its technical expertise and works with customers to develop and optimize the process for molding optical lenses.
Covestro has developed a novel simulation tool that allows:
- Quantitative simulation of cooling times via simulation modelling techniques and material descriptions
- Optimization of wall thickness distribution
Additional technical support offered by Covestro includes the development of gating concepts, rheological simulation and optimization, and process optimization at the customer’s site.
