Aluminum alloy castings are usually used to process many aluminum parts, which are also very common in our lives. However, if the surface treatment is not good during the processing, it will also have a great impact on the quality of products. Therefore, when we choose aluminum alloy castings There are many aspects to pay attention to, so what should be paid attention to? Do you know the surface treatment technology of aluminum alloy castings?

The coating process of aluminum alloy castings can generally be divided into spraying, powder spraying and electrophoresis. After surface treatment, 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 adversely affect the quality of the workpiece. Generally speaking, the spraying process can achieve better appearance quality, and the spraying has good gloss, color and weather resistance, and is usually used for applications with high appearance requirements, such as automotive exterior paint and motorcycle fuel tanks.

As we all know, the Tracks for Lawn mower processing system of aluminum alloy castings will affect the entire operation process, so what are the factors that affect aluminum alloy castings? The reasonable design of the low-pressure mold can clear the feeding channel in the aluminum alloy casting process, resulting in a good and rapid continuous condensation effect, To achieve condensation from the far end to the riser, prevent forging defects and improve output power, the preheating temperature of the mold is generally 400-450, the temperature of the aluminum alloy die-casting mold is too low or too high, it will destroy the reasonable temperature field of the mold, 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, and the type, size and thickness of the coating on the surface of the mold will directly affect the function of the casting. When aluminum alloy castings are used to produce low-pressure castings, it is necessary to control and inspect the quality of the castings, formulate rules and technical conditions, and control and inspect each specific product from raw and auxiliary materials to process compliance, and each process is strictly Control and inspect in accordance with process regulations and technical conditions.
