Fine metal stamping is mainly classified by process, which can be divided into two categories: separation process and forming process. Parting process can also be called blanking, which aims to separate fine stamping parts from sheet metal along a certain contour line and ensure the quality requirements of parting section together.

Fine metal stamping is an efficient production method. Multi position progressive die is selected, which can complete multiple stamping processes on a press, and realize automatic production from uncoiling, leveling, punching to forming and finishing. It has high production efficiency, good working conditions, low production cost and can produce thousands of pieces per minute. The purpose of the forming process is to make the sheet metal deform plastically under the condition of not breaking the blank, and to make the required shape and size of the workpiece.

Fine metal automobile sheet metal parts processing: with thin, uniform, light and strong features stamping can produce stamping parts with stiffeners, ribs, undulations or flanging which are difficult to be made by other methods, since then, its rigidity has been improved. Due to the selection of fine mold and workpiece accuracy can reach 0.01mm level, and the high repetition accuracy and common standard, it can punch out the hole socket, boss, etc.

Automobile stamping parts should have good optimization design methods, so stamping manufacturers take stamping optimization design as an important way to reduce the cost of automobile manufacturing, which can make the appearance of automobile beautiful. The air resistance is reduced, the number of stamping parts and solder joints are reduced, and the cost is effectively reduced.

Empirical methods. This method is mainly based on some empirical calculation formulas, so its application scope is affected. It is mainly applied to the developable stamping parts with simple shapes (such as rotating parts, bending parts, or stamping parts composed of these simple shapes). Generally speaking, the method of developing the free-form surface of plate parts by experience belongs to the method of adaptability. Its accuracy is affected by many factors such as the user's experience, the empirical formula used and the selection of specific process parameters. Its accuracy needs to be further improved.
