Cooling prediction for thick walled parts

Cooling simulation

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.
