ã€ALUMINIUM NETWORK】The quality of the aluminum used is not very good, and too much impurities will peel from inside. After the aluminum parts are shot blasted, the oxide layer on the aluminum parts will be destroyed. It can not be handled very cleanly. A part of the oxide layer remains on it.
Shot blasting is to make the work in the parts further compaction, usually about 3 kg force per square centimeter of force, such as the workpiece itself has the problem of die casting quality, such as blowholes, bubbles, cold septum, etc. Peeling occurs. This is not the same concept as die-casting and must be distinguished.
There are currently no effective methods for the above issues, and you can understand the basic approaches:
1, further improve the quality of the workpiece;
2, reduce the shot pressure;
3. Grinding of the shot blasting area, such as the bottom of the grinding problem, can be re-thrown.
