There are many dents when processing parts. How to prevent them

Generally, various errors will occur in the processing of precision parts or precision molds. Shrinkage and dents are very common phenomena. If dents always appear in the processing of parts or molds, we should pay attention to these. The following precision parts processing manufacturers will tell you how to prevent dents during processing.

1、 Dents in precision parts processing

1. When machining precision parts, if the cooling time is short, the parts will also be deformed;

2. During precision mold processing, if there is insufficient internal pressure, it is also easy to cause mold or parts deformation;

In this case, the thickness of each part of the mold is different from that of the forced cooling machine, and the thickness of each part of the mold is reduced at the edge of the product;

4. Because the place is too coarse and large, there is a depression. Methods: depression can be reduced or even eliminated by increasing stress and residence time. The key depends on their degree of depression, manufacturer and willingness (staying too long will reduce productivity).

To sum up, the main solutions to the dents that can be produced during the development of plastic mold injection molding are as follows:

1. Improve energy injection: pressure, speed, time and quantity, and increase back pressure to fill the mold;

2. During processing, make the temperature fluidity of the material smoother, reduce the shrinkage, and appropriately increase the mold temperature;

3. The gate is arranged in the thick part of the workpiece to improve the flow condition of the nozzle, runner and gate and reduce the material consumption;

4. Improve mold exhaust.
