aluminum alloy castingIt is usually used for the processing of many aluminum parts and 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 are choosingaluminum alloy castingAt that time, we need to pay attention to many aspects. So what should we pay attention to? You knowaluminum alloy castingThe surface treatment technology? Let's take a look.

aluminum alloy castingThe coating process can be generally 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 workpiece. 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,aluminum alloy castingThe processing system will affect the entire operation process, then the impact.aluminum alloy castingWhat are the factors?

The reasonable design of the low-pressure mold can dredge the feed channel in the aluminum alloy casting 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.Mold preheating temperature is generally400-450°C. If the temperature of the aluminum alloy casting 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.

Adoptaluminum alloy castingWhen producing 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 process regulations and technical conditions.
