Aluminum oxide processing Aluminum alloy casting are generally made of metal type, metal aluminum and aluminum alloy has a good mobility and plasticity, but in the process of easy to black, in the end how is it?
1. Process design is unreasonable. Aluminum alloy die casting in the cleaning or pressure inspection after improper handling, for the aluminum die casting mold to create the conditions of black, to speed up the formation of mildew.
2. Warehouse management is not in place. Aluminum alloy die casting stored in the warehouse at different heights, the moldy situation is also different.
3. Internal factors of aluminum alloy. A lot of aluminum die casting manufacturers in the Die Casting, machining processes, do not do any cleaning, or simply flush with water, can not be completely cleaned, Die Casting aluminum surface residual mold release agent, cutting fluid, saponification and other corrosive Substances and other stains, these stains to speed up the aluminum die-casting parts of the speed of black spots.
4. Aluminum external environmental factors. Aluminum is an active metal, in a certain temperature and humidity conditions easily oxidized black or moldy, which is determined by the characteristics of aluminum itself.
5. Use cleaning agent should not be. The choice of cleaning agent with a strong corrosive, resulting in corrosion corrosion of Die Casting aluminum.
