2019-08-20 09:30

  The quality of the aluminum used is not very good. If there are too many impurities in the inside, the skin will be peeled off. After the aluminum parts are shot blasted, the oxide layer on the aluminum part will be destroyed. The untreated can be cleaned, and some of the oxide layer remains. Above.

  Shot blasting is to make the workpiece further compacted. Usually, the force per square centimeter is about 3 kilograms. If the workpiece itself has die-casting quality problems, such as pores, bubbles, cold partitions, etc., it will be shot in real time. The phenomenon of peeling occurs, which is not the same concept as die-casting and is to be distinguished.

  There is currently no effective way to solve the above problems, you can understand the basic processing methods:

  1. Further improve the quality of the workpiece;

  2. Reduce the pressure of shot blasting;

  3. Grind the blasting part, such as the bottom of the blasting, and re-throw it.
