Stamping processing factory, processing hardware stamping parts, stainless steel drawing parts, carbon steel parts, automobile hardware stamping parts have good technology and economy. The important mark to measure its level is the number of stamping processes, the number and size of body assembly blocks, the structure of stamping parts and other factors. Reducing the number of processes in stamping process means reducing the number of stamping pieces, saving the number of tooling, simplifying the transmission device in stamping process, reducing the area occupied by operators and equipment, etc., which is an excellent measure to save investment and energy consumption. Therefore, hardware stamping manufacturers can take the design of stamping process number as an important way to reduce the cost of automobile manufacturing, even at the expense of improving product design to meet the requirements According to the requirements of the manufacturing process, the reasonable total body component block with the largest size as possible, such as the left and right side plates of the whole body and the roof cover plate, can not only make the car appearance more beautiful and practical, reduce the air resistance, but also reduce the number of stamping parts and welding spots, and effectively reduce the cost.

It is a complex problem to deal with the dispersion and concentration of the working procedure when making the stamping process. It depends on the batch size, structural shape, quality requirements, process characteristics, etc. For the automotive stamping parts which are usually produced in large quantities, we should try our best to adopt the scheme of centralized working procedure and adopt compound or progressive die for stamping, so as to improve the productivity and achieve safety production. The practical experience shows that for the compound die, the number of processes concentrated on a pair of dies should not be too much, generally 2-3 processes, up to 4. For the progressive die, the number of processes concentrated can be more, because the layout range of the die structure has more freedom.
