Sheet metal is a comprehensive cold working process for sheet metal. It is widely used in the research and development of mechanical equipment and involves many products, including self-service terminals, cabinets, chassis, machine rooms, power distribution cabinets, CNC machine tools, etc. For sheet metal product design, it is very important for designers to skillfully use sheet metal technology, which will directly affect the difficulty and success of product manufacturing. Sheet metal process involves many aspects, including sheet metal construction method, sheet metal punching and cutting design, groove and punching, molding printing, die and punching, bending, etc. In the design of sheet metal products, designers need to have an in-depth understanding of the material of the product and the applicable processing technology. They should take into account the later production and manufacturing of the product, and comprehensively consider the modeling design, color expression, material selection, man-machine interface and other aspects. On the basis of realizing the structure and function of the equipment, they should integrate their own creative and flexible design to make the product simple and beautiful.
