In the types of steel plate specifications, whether it is a cut-to-length plate or a coil, the selling price of the same material and thickness of the material is different with different coil widths. Therefore, in order to reduce costs, it is necessary to work hard on the formulation of the procurement roll width, and try to select the roll width range without price increase under the premise of ensuring the utilization of materials. For example, for the cut-to-length plate, try to choose the appropriate size, after the cutting from the steel plant is completed, there is no need to perform secondary cutting to reduce the cutting cost; Shearing workload improves work efficiency.

The thickness of the plate has deviation requirements, usually within the allowable range of deviation, the plate with the lower deviation should be selected first.

Determining the shape and size of the unfolded sheet of stamping parts is the prerequisite for analyzing the degree of deformation of stamping parts, designing processability and drawing up process regulations. If the shape of the sheet is appropriate, not only the uneven distribution of deformation along the sheet can be significantly improved, but also the forming limit can be increased, the height of the lugs can be reduced, and the margin for trimming can be reduced. In addition, for some parts that are directly formed after blanking, if the accurate sheet shape and size can be given, the number of mold trial adjustments can be reduced, thereby shortening the production cycle and improving productivity.

When selecting materials for product design, avoid using high-grade materials to cause excess product performance. At the same time, on the premise of meeting product and process requirements, try to choose the material and thickness of the existing mass-produced models to form a material platform for subsequent Provide convenience for purchasing and inventory management. For example, the key performance requirement of ordinary cold-rolled sheet is its ductility, so try to choose low-grade materials under the requirements of product quality. For the choice of material thickness, in addition to considering the strength and weight of the body after forming, it is also necessary to pay attention to the popularization of material thickness. Because of the special thickness of the material, it is difficult for suppliers to supply, and the price is also high.
