What problems should be paid attention to when selecting precision metal stamping materials

Precision metal stamping parts are used in all areas of our lives. Then what issues should we pay attention to when selecting precision metal stamping materials: 1. Among the standard types of steel plates, whether it is a cut-to-length plate or a coil, the same raw material and material thickness have different sales prices for 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 data. For example, try to select the appropriate standard size for the cut-to-length plate. After the cutting from the steel mill is completed, no secondary shearing is required to reduce the cutting cost; for the coiled plate, try to choose the coil material standard and technology for uncoiling forming to reduce the secondary cutting. Cutting workload improves work efficiency. 2. The thickness of precision metal stamping plates has error requirements, usually within the allowable range of error, the plate with the lower error should be selected first. 3. Confirming the shape and size of the open sheet of precision metal stamping is the prerequisite for analyzing the degree of deformation of stamping parts, planning the craftsmanship and drawing up the 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 improved, and the height of the lug can be reduced, and the trimming margin can be reduced. In addition, for some parts that are directly formed after blanking, if the precise shape and size of the sheet can be given, the number of mold trial adjustments can be reduced, and then the production cycle can be shortened, and the production rate can be improved. 4. When selecting materials for precision metal stamping planning, prevent the selection of high-brand raw materials from causing excess product functions. At the same time, on the premise of satisfying the product and process requirements, try to select the raw materials, material thickness, and composition materials used in the existing mass-produced models The platform provides convenience for subsequent purchases and inventory management. For example, the key function requirement of general cold-rolled sheet is its ductility, so try to choose low-brand materials under the requirements of product quality. Regarding 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 popularity of material thickness. Due to the thickness of special materials, it is difficult for suppliers to supply and the price is also high.
