Aluminum die casting manufacturers tell you how to polish and infiltrate cast aluminum parts

 After the aluminum casting is shaken, the surface quality is already very high, and it can even achieve "mirror" light, and it has a passivation effect. No further processing is required for non-special customer requirements.

 "Electropolishing" can further improve the surface quality. Oxidation can improve corrosion resistance. There is no need to shake light. Dyeing can improve the corrosion resistance and obtain the desired color. There is no need to shake light. Electrochemical oxidation of oxidized metals or alloys of aluminum castings. A metal or alloy product is used as an anode, and an oxide film is formed on the surface by electrolysis. The metal oxide film changes the surface state and properties, such as surface coloring, improving corrosion resistance, enhancing wear resistance and hardness, and protecting metal surfaces. For aluminum castings, anodizing is often encountered, but it has to be said that the process of casting aluminum alloys is difficult to do. Profiles and pure aluminum are very good, which is related to the composition of their own alloys.

 Aluminum alloy die casting

Precision cast aluminum is individually continuously cast according to different thicknesses. Using the new results of casting technology, the molten metal is continuously fed, eliminating the defects caused by gaps and joints. Since the two sides of the plate dissipate heat at a steady speed, the thermal gradient of the aluminum plate is stable. Because of its granular structure and stress release characteristics after casting, precision cast aluminum can be high-speed cutting with minimal deformation. Using the correct processing method, the tolerance can be kept within 0.1 wire. Plate shape tolerance: thickness 6.35-15.875mm, large tolerance of 0.381mm, thickness of 19.05-152.4mm, large tolerance of 0.127mm, when the temperature reaches 420℃, it can still maintain the same as before. Each piece of material is inspected for thickness and flatness by laser. It is widely used in automobile industry, aviation industry, medical equipment, printing machinery, precision industry, etc. Precision cast aluminum is developed to meet the high precision requirements of modern industry.

Aluminum die-casting is a kind of die-casting part. It uses a die-casting mechanical die-casting machine equipped with a casting mold to pour the heated liquid aluminum or aluminum alloy into the inlet of the die-casting machine, and then die-cast by the die-casting machine to cast out the mold. Aluminum parts or aluminum alloy parts with restricted shapes and sizes. Such parts are usually called aluminum die-casting parts. Aluminum die-casting parts have different names in different places, such as aluminum die-casting parts, die-casting aluminum, die-casting aluminum parts, die-casting aluminum parts, aluminum die-casting parts, aluminum alloy die-casting parts, etc. Aluminum die castings are widely used in various industries such as internal combustion engine production, automobile manufacturing, motorcycle manufacturing, electric motor manufacturing, transmission machinery manufacturing, oil pump manufacturing, landscaping, electric power construction, precision instruments, and architectural decoration.
