First of all, selecting suitable materials is the first step of surface treatment of freezer shell. Commonly used materials are stainless steel, galvanized sheet, aluminum alloy, etc. These materials have sufficient strength and hardness, as well as good corrosion resistance and aesthetics, so they are widely used to manufacture freezers. Among them, stainless steel has better corrosion resistance and aesthetics, so it is widely used to manufacture high-grade freezers.
Secondly, the surface treatment of the refrigerator shell also includes the treatment process in the processing process. Generally speaking, the processing technology in the processing process includes stamping, cutting, welding and other processes. These processes require operators to have high processing technology and professional knowledge to ensure the quality and accuracy of the refrigerator shell.
Finally, the surface treatment of the refrigerator shell needs surface treatment. These surface treatments include spraying, electrophoretic coating, chromium plating and polishing. Different surface treatment methods can produce different effects, such as smoother surface after polishing and more decorative after spraying.
To sum up, the surface treatment of freezer shell is a very key link in freezer manufacturing. In the process of processing, it is necessary to strictly control the appropriate material selection, processing technology and surface treatment to ensure the strength, durability and aesthetics of the freezer.
