A sheet metal bend folds a 2D tablet into a 3D object. Its production and processing must be a folding bed and the relative bending die for actual operation. It also has a certain bending order. The mechanism is to fold first without interfering with the next knife, and then intervene after folding.

Weld. Welding is the purpose of welding several parts together and precision machining of sheet metal to achieve production and processing. Its production and processing methods are generally as follows: CO2 gas shielded welding, argon arc welding machine, welding, robot welding, etc. The selection of this welding method depends on the specific regulations and raw materials. In general, the stainless steel plate welding selection of CO2 gas shielded welding. Argon arc welding machine is selected for welding of aluminum alloy plate. Robot welding is suitable for places with large raw materials and long welding.

Surface treatment. Generally speaking, the surface treatment includes phosphating film, electroplating process colorful zinc, chromium trioxide, baking process, air oxidation, etc. Phosphating film is usually used for cold rolled plate and electrolytic thick steel plate. Its primary function is to apply a protective film on the raw material to avoid air oxidation. Second, it can improve the adhesion of the baking process.
