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 must pay attention to many aspects 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 product quality. Generally, the spraying process can obtain better appearance quality. Spray coatings have good gloss, color and weather resistance, and are usually used in applications that require high appearance, such as automotive outer coatings and motorcycle fuel tanks.

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

The reasonable design of the low-pressure mold can dredge the feed channel in the aluminum alloy processing process, produce a good and rapid sequential condensation effect, realize the condensation from the far end to the riser, prevent forging defects, and increase the output power. Mold preheating temperature is generally suitable to reach400-450°C. If the temperature of the aluminum alloy processing mold is too low or too high, it will destroy the reasonable temperature field of the mold, which will make the casting difficult to form or the pass rate is low. The coating on the surface of the mold has thermal shock resistance. 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, the quality of castings needs to be controlled and checked. We should formulate rules and technical conditions to control and inspect every specific product from raw materials and auxiliary materials to process compliance. Each process is controlled and inspected in strict accordance with the process regulations and technical conditions.
