The operating principle of the injection molding machine

2022-01-12

The evaluation of plastic products(injection molding machine) mainly includes three aspects: the first is the appearance quality, including integrity, color, luster and so on; The second is the accuracy between size and relative position; The third is the physical, chemical and electrical properties corresponding to the application. These quality requirements are different according to the different application occasions of products, and the required scales are also different. The defects of injection molding machine mainly lie in mold design, manufacturing accuracy and wear degree. But in fact, the technicians of plastic processing plants often suffer from the difficult situation of using technological means to make up for the problems caused by mold defects.

The adjustment of process in the production process(injection molding machine) is a necessary way to improve the product quality and output. Because 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 more times. If the pressure, temperature and time are all adjusted together, it is easy to cause confusion and misunderstanding. If there is a problem, I don't know the reason. There are many measures and means to adjust the process. For example, there are more than ten possible solutions to the problem of dissatisfaction with product injection. Only by selecting one or two main solutions to solve the crux of the problem can we really solve the problem. In addition, attention should also be paid to the dialectical relationship in the solution. For example, if the product is sunken, sometimes the material temperature should be increased and sometimes the material temperature should be reduced; Sometimes it is necessary to increase the material quantity, and sometimes it is necessary to reduce the material quantity. We should recognize the feasibility of reverse measures to solve the problem.
