When stainless steel castings are used, milky white black spots often appear after anodizing film staining agent. This situation occurs because the aluminum alloy die-casting mechanism is loose, the pores are large, and there are many kinds of metal and non-metallic material residues, so the quality of the air oxide film is generally more difficult.

Therefore, the method to prevent environmental pollution of aluminum alloy die casting is the high working voltage and high current intensity impact method, that is, the high voltage electric shock method is selected. Splice. The surface sanding and polishing method is to leave the polished aluminum powder filler in some of the gaps left in the air, so that the resulting gaps are connected and used as a bridge for road bridges.

You can also choose surface shot blasting. This method is to hit the gap with a round head hammer, press and hit to close it, which can exceed the goal of a continuous piece. For aluminum alloy die-casting, people should choose the corresponding matching method according to the degree of environmental pollution. If the manufacturer wants to produce and manufacture qualified aluminum alloy die castings, he must have a set of scientific processing technology content, and the staff must strictly implement it during the entire processing process.

The qualified processing technology of aluminum alloy die castings is obtained in continuous experiments and explorations. Therefore, a set of reasonable production process steps is essential for the production of high-quality qualified castings. The manufacturing process is formulated by the processing technology staff and implemented by the master workers. When making the processing technology, the processing technology personnel must strictly implement the processing technology formulation rules and be implemented by the superior. The workers will operate and then the workers will operate. .
