If it is a training institution, it will take about 3-6 months to get started, and the basic operation should be able to pass. You can apply for a job yourself. If it is a higher vocational college or technical school, it usually takes 1-3 years.

Up to now, there is no relatively complete definition of sheet metal processing technology. According to a definition in foreign professional journals, it can be defined as: sheet metal is a comprehensive cold working process of shearing, punching/cutting/compounding, folding, riveting, splicing and forming metal plates (usually less than 6mm) (such as automobile bodies). Its remarkable feature is that the thickness of the same part is consistent.

Process characteristics:

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.

With the more and more extensive application of sheet metal, sheet metal design has become a very important part of product development. Mechanical engineers must master the design skills of sheet metal skillfully, so that the designed sheet metal can not only meet the requirements of product function and appearance, but also make the stamping die simple to manufacture and low in cost.
