First analysis of the product structure characteristics and performance, and the plastic composition and technical characteristics, plastic molding process characteristics of the plastic parts of the shape features, size, dimensioning methods, accuracy, surface quality and material properties and other factors. Second, the choice of injection machine and its parameter calibration, the determination of mold cavity, the choice of sub-surface, casting system, exhaust system, temperature control system, forming part structural design, lateral type Pulling Mechanism Design structural components of the design, orientation and design and launch of the main molding body parts such as the processing technology were described in detail. In the design process also had a lot of computation, including injection molding machine clamping force, the maximum injection quantity, injection pressure, molding parts and die size of the calculation of stroke size mold and mold and injection machine check to install some of the relevant dimensions proof, and so. In the design process using the PRO / ENGNEER system software on the plastic three-dimensional modeling, and plastic parts
