Plate has the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost and good mass production performance, and has been widely used in electronic appliances, communications, automobile industry, medical devices and other fields. For example, sheet metal is an indispensable part in computer cases, mobile phones and MP3 players.
Modern metal plate technology includes filament winding, laser cutting, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal plate bending forming, die forging, water jet cutting and precision welding.
Surface treatment of sheet metal parts is also a very important link in sheet metal processing, because it can prevent parts from rusting and beautify the appearance of products. The function of surface pretreatment of sheet metal parts is mainly to remove oil stain, scale and rust. Prepare for surface post-treatment, which mainly includes painting (baking), plastic spraying and antirust coating.
