Injection Molding Machine has the ability to form plastic products with complex appearance, precise size or dense texture with metal inserts at one time. It is widely used in household appliances, automobiles, medical treatment, industry and various fields of people's daily life.

The injection molding process has good adaptability to the processing of various plastics, high production capacity, and easy automation. The working principle of the injection molding machine is similar to that of the injection syringe. It is the process of injecting the plasticized molten plastic into the closed mold cavity with the help of the thrust of the screw and obtaining the product after curing and shaping. Injection molding is a cycle process, each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - mold filling and cooling - mold opening and taking out. After the plastic parts are taken out, the mold is closed again for the next cycle.

There are three main aspects to the evaluation of plastic products, the first is the appearance quality, including integrity, color, gloss, etc.; the second is the accuracy of size and relative position; the third is the physical properties, chemical properties, electrical properties, etc. These quality requirements are also different according to the different occasions where the products are used. The defects of the products mainly lie in the design of the mold, the manufacturing accuracy and the degree of wear. But in fact, technicians in plastic processing plants often suffer from the difficult situation of using technological means to make up for the problems caused by mold defects and have little effect.​​

The adjustment of the process in the injection molding production process is a necessary way to improve the quality and output of the product. Since the injection molding cycle itself is very short, if the process conditions are not well mastered, there will be an endless stream of waste products. When adjusting the process, it is best to change only one condition at a time, and observe it several times. If the pressure, temperature and time are all adjusted together, it is easy to cause confusion and misunderstanding, and there is no reason for the problem. There are various measures and means to adjust the process. For example, there are more than ten possible solutions to solve the problem of dissatisfaction with products. Only by choosing one or two main solutions to solve the crux of the problem can the problem be truly solved.
