　　Cleaning of zinc alloy die casting machining operation points

　　Zinc alloy die casting processing is a molding of efficient metal parts processing technology, through zinc alloy die casting processing production products, can do a few seconds to produce a die casting, of course, these die casting parts are only blank parts, need to go through a series of processing processes to become usable finished products, and die casting cleaning is one of them.

　　Zinc alloy die casting processing is a series of processing processes, including die casting, die-casting, stripping, tapping, polishing, surface treatment and other steps, and cleaning is a small process between polishing and surface treatment, because polishing needs to use polishing paste, it will stick to the surface of die casting, surface treatment has a certain impact, so it needs to be cleaned.

　　Zinc alloy die-casting processing cleaning needs to use high-quality washing powder (B type), small particles, large density, less foam, into the water to dissolve quickly, hand contact solution without burning feel, the solution is clear and smooth, decontamination effect is obvious. Special attention should be paid to: the water temperature of the enzyme washing powder should not exceed 60 ° C, otherwise, the enzyme will lose its activity, affecting the oil removal effect. In addition, for large zinc alloy die-casting parts, you can use a brush or rag to stick on the washing powder to manually wipe the oil.
