MOLDFLOW software to simulate the injection of plastic melt in the process of filling, cooling and flow, ensuring access to high-quality parts. Breaking traditional mold structure design test mode, the process of repair molds, to reduce costs, improve productivity purposes. Obtained the best quality in the simulation results of the data, parameters after the design used as the basis for the mold. The design includes: （1）Moldflow injection molding simulation of melt flow in the cavity is very complex process with many factors. Such as polymer properties, parts structure, temperature, pressure, time, and injection mold structure and other related equipment. Quantitative simulation of the molding window molding process given the state parameters (such as pressure, temperature, speed, etc.). (2) Simulation based on the parameters of the molding window state the structural design of the injection mold. Such as the choice of injection machine, injection system, molded parts, mold bodies, stripping institutions and cooling system design, drawing die part and assembly drawings, etc..
