Plastic shell is used in all aspects of life because of its strong insulation. If these items are made of metal, the insulation is very poor. And a protective layer is needed. In this case, compared with metal materials, plastic materials are not only cheaper, ensure safety, but also have strong insulation properties. What should plastic shell manufacturers pay attention to during production and processing?
1、 Forming cycle of workpiece
This includes plastic time and product cooling time, which have a profound impact on product quality.
2、 Mold temperature
Different plastic particles have different temperatures and crystallization rates. Product appearance, deformation, size and plastic mold have different requirements, which makes the mold used in the plastic temperature and product requirements are different. In other cases, the control of mold temperature is different.
3、 Barrel temperature and melting temperature of plastic shell
The melt temperature can be measured at the nozzle or by air injection, which plays an important role in the flow characteristics of melt.
4、 Injection speed
Injection speed has an important impact on the appearance quality of the product, which is usually achieved by adjusting the amount of oil supplied to the injection cylinder per unit time.
5： Injection pressure of plastic shell parts
The plastic shell faces great resistance when filling the cavity, which makes the injection pressure directly determine the size, weight, density and appearance of the product. If any of these factors are affected, the product will become waste.
