1. In the type of steel plate specifications, whether it is fixed size plate or coil plate, the same material, material thickness, different roll width，sales prices are different. If the size board as far as possible to choose the appropriate size, from the steel mill after the completion of shear, do not have to carry out two shear, reduce the cost of cutting; For the coiling plate, try to choose the coiling specification and process of uncoiling forming, reduce the workload of secondary shearing, improve the working efficiency.
2. There are deviation requirements for the thickness of the plate. Usually, within the allowable range of deviation, the plate with the deviation should be selected first.
3. To determine the shape and size of the stamping parts of the expansion sheet, is to analyze the degree of deformation of stamping parts, design technology and draw up the premise of process rules. If the shape of the sheet material is suitable, not only the phenomenon of uneven distribution of deformation along the sheet material can be significantly improved, but also the forming limit can be increased, and can reduce the height of the lug, reduce the margin of cutting. In addition, for some parts formed directly after blanking, if the precise shape and size of the sheet metal can be given, it can reduce the number of mold test and adjustment, so as to shorten the production cycle and improve productivity.
4. In product design and material selection, avoid the selection of high-grade materials to cause excess product performance. At the same time, on the premise of meeting the product and process requirements, try to choose the material and material thickness used by the existing mass-produced models to form a material platform, so as to provide convenience for subsequent procurement and inventory management. For example, the key performance requirement of ordinary cold rolled sheet is its ductility, so in line with the requirements of product quality as far as possible to choose low grade materials. For the selection of material thickness, in addition to considering the strength and weight of the body after forming, but also pay attention to the popularity of material thickness. Because of the special thick material, it is difficult for suppliers to supply, and the price is high.
