The injection process of animal pattern injection molding machine plastic parts mainly includes four stages: feeding, plasticizing, injection filling and demoulding. These four stages are a complete continuous process, which directly affects the quality of plastic products. Adding too much or too little material during the feeding process will affect whether the final good plastic parts can be obtained, so the material must be determined according to demand to ensure stable operation and uniform plastic plasticization; After feeding, it is necessary to heat the plastic of the cylinder to transform it from a solid state into a viscous flow state with good plasticity, that is, the plasticization process.

The filling quality determines the product quality, and the filling quality is directly related to the structure of the hydraulic system. During the filling process, the polymer viscous flow system formed by the front part of the screw and the rear part of the screw form a closed fluid resistance system through the injection cylinder and the oil circuit system. Injection molding rate is affected by oil system parameters, medium, pressure, system structure and hydraulic stiffness. Therefore, the level of the hydraulic system is closely related to the quality of the injection.
The system is the injection molding machine "nerve center" system, control a variety of program actions, to achieve the time, position, pressure, speed, speed control and adjustment, by a variety of relay components, electronic components, detection components and automatic instruments. The control system and hydraulic system are combined to achieve precise, stable control and adjustment of the injection machine process. Such as clamping speed, low pressure mold protection, mold control, etc., will affect the molding cycle of the product, as well as the reliable low pressure mold protection of the mold, accurate mold opening positioning, etc., will affect the molding cycle of the product and the reliability of the mold. The influence of injection speed, holding pressure, screw speed, barrel temperature and other factors on the injection process conditions also needs precise control.
