Aluminum die casting production operation requirements Aluminum die casting is one of the advanced metal forming methods. It is an effective way to achieve less chipping and no chipping. It is widely used and develops quickly. At present, die-casting alloys are no longer limited to non-ferrous metals such as zinc, aluminum, magnesium and copper, but are also gradually expanded to die-cast cast iron and steel castings. The size and weight of die castings depend on the power of the die casting machine. Due to the increasing power of the die casting machine, the size of the casting can be from a few millimeters to 1 to 2m; the weight can be from a few grams to tens of kilograms. Abroad can be die-casting parts with a diameter of 2m and a weight of 50kg.

There must be an effective forging process. That is, according to the casting structure, net weight and specifications, the characteristics of forged aluminum alloys and manufacturing standards, select the appropriate clinical diagnosis surface and styling design, core making method, and effectively set the forged tendons, cold iron, riser and pouring system software . To ensure casting. Without the improvement of the quality of machine tool castings, the development trend of CNC lathe equipment manufacturing industry and the improvement of the overall level, there is no way to talk about it, which will ultimately harm the market competitiveness of CNC lathe equipment manufacturing in the sales market in my country. Continuously improve the quality of machine tool castings, thereby ensuring the overall improvement of the production level of CNC lathes.

Products used for aluminum die castings in acidic and alkaline environments require products to be resistant to corrosion. So the conventional method we use to detect the corrosion resistance of aluminum die castings is the salt spray test. The salt spray test is an environmental test that mainly uses artificially simulated salt spray environmental conditions created by the salt spray test equipment to assess the corrosion resistance of zinc alloy die castings.

The salt spray test is an environmental test that mainly uses artificially simulated salt spray environmental conditions created by the salt spray test equipment to assess the corrosion resistance of zinc alloy die castings. However, the salt spray test is performed on the outer surface of the die-casting parts, and the rough parts are not recommended for testing. Because the chemical properties of zinc and aluminum are very active, it is easy to oxidize when stored under normal conditions. Therefore, for some products that have requirements for corrosion resistance, wear resistance, and oxidation resistance, Dongguan Die Casting Factory recommends that customers do some surface treatment to increase the performance of their products.
