Plastic shell of power supplyThe processing problem has always been a concern of everyone. In the case of power plastic shell processing, all kinds of problems we all want to deal with. If we want to better carry out the processing of power plastic shell, but many friends do not understand the processing process of power plastic shell, resulting in many problems that cannot be analyzed in depth, so today we will explain the processing process of power plastic shell.

Process flow 1 of power supply plastic shell processing: the first thing you need to do in processing power supply plastic shell is to prepare the raw materials of power supply plastic shell in advance. Generally, the raw materials selected for power supply plastic shell are selected PC materials, which are not only excellent impact resistance, but also non-toxic and harmless materials, with high definition, so the selection of PC materials for power supply plastic shell is the first step for everyone to process power supply plastic shell.

Process flow 2 of power plastic shell: after the power plastic shell is selected, what you need to do next is to solve the material of power plastic shell. The first step in solving the material of power plastic shell is the mixing and air drying of materials. The mixing and air drying of the power supply plastic shell is to volatilize the water in the power supply plastic shell material, meet the processing standard of the power supply plastic shell material, and prevent vacuum pump bubbles from appearing on the surface of the power supply plastic shell.

Process flow 3 of power plastic shell processing: after the material of power plastic shell is solved, the injection molding process of power plastic shell is finished. In the process of applying for registration and molding, we not only need to control the temperature under the processing of the plastic shell of the power supply, but also the injection rate of the injection process of the plastic shell of the power supply is very unique. Generally, various injection methods are used, and the injection speed is relatively slow.
