Why Bi-Injection Molding Simulation?

Bi-Injection Molding is one variant of multiple-component molding process. It is generally applied to two-colored plastics, such as automotive lamps, mobile casting, or toothbrush. In the process, two plastic materials are injected into one mold cavity via two independent gates. The plastic flows will meet in the cavity and result in a variety of configuration. The position of the border line can be defined through flow rate controls. Therefore, it is crucial to utilize Moldex3D in the verification and optimization of part/mold designs, process parameters, etc.

  • Select plastic materials for two melt entrances
  • Estimate the position of the welding line through melt front advancement
  • Define independent filling and packing parameters for each material
  • Determine gating design (gate type, location, ect) to achieve appearance requirement

What Can Moldex3D Do?

  • Visualize the melt front behaviors from two melt entrances
  • Predict the potential locations of welding lines
  • Trace the flow orientation of polymer particles
  • Demonstrate the flow rate variation from two melt entrances
  • Support parallel processing to speed up the simulation process
