Why Plastic Optics Simulation?

Injection molded plastics, widely used in optical applications, have become smaller and lighter. The flow-induced anisotropic property would be significant in smaller filling cavities. As a result, key optical issues, such as birefringence, retardation, or polarization, would be a bottleneck in the design-to-manufacturing process. Based on the three-dimensional filling and the viscoelastic analysis, Moldex3D Optics helps designers in evaluation of the optical performance and process conditions. Furthermore, integrated with CODE V, users are allowed to export the deformed shape and refractive distribution into CODE V for design verification and optimization.

What Can Moldex3D Do?

  • Visualize the filling pattern of the optical part
  • Visualize optical properties, including birefringence, retardation, fringed pattern, etc.
  • Predict potential defects, such as short shot, flow imbalance, shrinkage, or warpage
  • Optimize process conditions, such as filling speed, packing pressure, or cooling design
  • Provide deformation and non-uniform refractive index prediction based on the integration with CODE V
  • Optimize gate and runner design and improve product quality
