Sheet metal processing overview
Sheet metal processing is a kind of metal processing technology, which usually refers to a comprehensive cold deformation processing technology for metal sheets, including shearing, punching/cutting/compositing, folding, welding, riveting, splicing, forming, etc., during the processing , the thickness of the metal sheet does not change. Metal processing processes corresponding to sheet metal processes include casting, forging, machining, etc., and the metal thickness of their products is usually inconsistent.
According to the different processing methods, the sheet metal process is divided into manual sheet metal, stamping and CNC sheet metal. At present, manual sheet metal is mainly concentrated in the fields of auto repair, art, advertising, etc.; stamping sheet metal is suitable for products with a single variety, large output, small structure, and relatively stable products; CNC sheet metal is suitable for small batches and high variety Wide variety of products in large sizes.

The history of the development of sheet metal technology can be said to have a long history. Starting from the bronze and iron ware in ancient times, people used various methods to smelt metal materials. With the improvement of smelting technology, metal plate materials were gradually smelted, and learned to use some Tools process these sheet metal materials, which is the prototype of the sheet metal process. The history of modern sheet metal technology is not long. The application of stamping equipment and cold stamping dies in the field of sheet metal processing and the popularization of CNC automation equipment are two milestones in the development of sheet metal technology. The former gave birth to stamping, and the latter gave birth to CNC sheet metal.
