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.
