The application scale of injection molding processing parts is becoming more and more widespread, from simple tableware, kitchenware to messy mechanical parts, electronic product shells, etc. are useful for plastic parts, but the injection molding processing parts of electronic product shells have higher requirements for precision, so what factors determine the precision of electronic product injection molding processing parts?

The following GonSon
injection molding processing factory of the editor to give you a detailed introduction, the details are as follows.
Injection molding processing
Off the mold pressure: in principle, it should be greater than the total pressure of plastic injection into the mold, in order not to get out of the burr as a benchmark.
Pressure and speed have part of the same connection to the purpose of the action in the mold are to make the material into the mold can be uniform, completely, the right amount of full of all corners.
Too low will be short shot, shrinkage, too high has a hairy head, too full, sticky mold, scorching, easy to damage the mold and high internal stress and other undesirable phenomena.
The speed of the injection molding process is to decide the material in the mold sprue and the situation of the product, fast with burrs, overfull, scorched, slow will appear short shot, shrinkage, combined with bad easy to break.
The temperature of the
injection molding process is different from material to material, the temperature varies, too low melt glue is not transparent and leads to uneven color, the internal stress of the product increases.
The temperature of the
injection molding process is too low and the pressure is too high, which may cause the screw to crack, too high, the product has a burr, and the temperature difference due to cooling, causing shortening. The material will decompose, become yellow, discolored, easy to crack. The cooling time becomes longer and the gas is not easily discharged.
