Aluminum alloy processing is usually used for the processing of many aluminum parts, and it is also very common in our lives. However, if the surface treatment is not good during processing, it will also have a great impact on product quality. Therefore, we need to pay attention to many problems when choosing this aluminum alloy casting. So what should we pay attention to? Do you know the surface treatment technology of aluminum alloy workpieces? Let's take a look.

The coating process of aluminum alloy processing can usually be divided into spraying, powder spraying and electrophoresis. After the surface treatment of the workpiece, according to the appearance and corrosion resistance requirements of different workpieces, select the appropriate spraying process and equipment, and pay attention to the control of leveling, drying and cooling, otherwise it will have a negative impact on the quality of the product. Generally speaking, the spraying process can achieve better appearance quality. Spraying has good gloss, color and weather resistance, and is usually used in applications that require high appearance, such as automotive exterior coatings and motorcycle fuel tanks.

As we all know, the processing system of aluminum alloy processing will affect the whole operation process, so what are the factors that affect the processing of aluminum alloy?

The reasonable design of the low-pressure mold can dredge the feed channel in the aluminum alloy processing process, produce a good and rapid continuous condensation effect, realize the condensation from the far end to the riser, prevent forging defects, and increase the output power. The mold preheating temperature is generally reached.400-450 ℃ is appropriate. If the temperature of the aluminum alloy processing mold is too low or too high, the reasonable temperature field of the mold will be destroyed, and the casting is difficult to form or the pass rate is low. The coating on the surface of the mold has the ability to resist thermal shock. The type, size and thickness of the spray coating on the surface of the mold will directly affect the function of the casting.

In the production of low pressure castings, it is necessary to control and inspect the quality of the castings. Formulate rules and regulations and technical conditions to control and inspect the compliance of each specific product from raw and auxiliary materials to process. Each process is strictly controlled and inspected in accordance with the aluminum alloy processing procedures and technical conditions.
