Numerical Simulation of Differential Injection Molding Based on Moldex 3D

Differential injection molding is one of the key technologies for micro-manufacture. The mechanism of melt pump based on the differential injection molding is presented. The differential injection molding system is added into the traditional injection machines. Melt is plasticized by the plastication system, then after being split, pressurized and measured by the differential system, it enters the cavity to realize the function of multiple micro injection molding machines. Moldex 3D software is used to simulate the filling history of the micro-structure via differential injection molding technology. The product's filling volume under different processing parameters is compared, which provides theoretical basis for the optimization of the molding parameters in differential injection molding technology.
