Release time:2024-11-27

Now people have far more requirements for plastic shells than before, and now it is more and more common to choose custom plastic shells. In some links of developing custom plastic shells, the steps of customizing plastic shells are very concerned. If you want to know what the steps of customizing plastic shells are, then in order to let us know clearly what the steps of customizing plastic shells are.


The first step in customizing the plastic shell is for the manufacturer of the plastic shell to make a necessary decision and make clear what kind of plastic shell the relevant customers need, so as to facilitate the later production and processing of the plastic shell.

After selecting the plastic shell material, the step of customizing the plastic shell reaches the step of understanding the material. In this link, what you need to do is put the selected material into the middle of the temperature range of 100 ° -120 ° and dry the moisture in the plastic shell material according to the drying treatment of 4 hours, so as to realize the requirements of injection molding.


After the drying of plastic shell materials is completed, the step of customizing the plastic shell comes to the important injection molding link. In the production and processing of plastic shell, we must adjust the problem of plastic shell injection molding, and the temperature should be controlled between 240 ° -320 °. Otherwise, some defects will appear after the production and processing of the plastic shell. During the injection molding process of the plastic shell, we must pay attention to the injection rate and inoculation method. Only by mastering this key phenomenon can we produce and process the plastic shell well.


Until the end of this link, the plastic shell quality inspection can complete all the steps of customizing the plastic shell.
