Some methods to prevent oxidation of stainless steel castings

When using stainless steel castings, milky black spots often appear after anodizing the film dye. This happens because the aluminum alloy die-casting mechanism is loose, has large pores, and contains residues of various metal and non-metal materials. , so the quality of air oxidation films is generally 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. In the early stage of air oxidation of aluminum alloy die-casting, high-voltage electric shock is selected to make part of the oxidized aluminum alloy parts press high-voltage electric shock again. The joining, 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 can be connected to serve as bridges for highway bridges.

You can also choose surface shot blasting. This method is to use a ball-head hammer to hit the gap, and press and hit to close it, which can achieve the purpose of connecting one piece. For aluminum alloy die-casting, people should choose the corresponding shot blasting according to the degree of environmental pollution. Corresponding matching method. If manufacturers want to produce and manufacture qualified aluminum alloy die-casting parts, they must have a set of scientific processing technology content and strictly follow the operating procedures during processing.

The qualified processing technology of aluminum alloy die-casting parts is obtained through continuous experiments and exploration. Therefore, a set of reasonable production process steps is crucial to the production of high-quality qualified castings. The manufacturing process is formulated by the processing technology staff. It is implemented by the master workers. When the processing technology is formulated, the processing technology personnel must strictly implement the processing technology formulation rules and implement it by the superior leaders. The workers will operate it and then the workers will operate it.
