What issues should be noted when selecting materials for metal stamping parts?

In terms of steel plate specifications, whether it is a fixed length plate or a coil plate, materials of the same material and thickness have different coil widths and sales prices. So, in order to reduce costs, efforts need to be made in formulating the width of the purchased rolls, while ensuring material utilization, and selecting roll width ranges that do not increase prices as much as possible. For fixed length plates, it is advisable to choose appropriate specifications and sizes. After cutting from the steel mill, there is no need for secondary cutting to reduce cutting costs; For coil plates, it is advisable to choose the specifications and process of the coil material formed by unwinding to reduce the workload of secondary shearing and improve work efficiency.
2. There is a requirement for deviation in the thickness of the board, and usually within the allowable range of deviation, the board with the lower deviation should be selected first.
3. Determining the shape and size of the unfolded sheet metal for stamping parts is a prerequisite for analyzing the degree of deformation of stamping parts, designing processability, and formulating process specifications. If the shape of the sheet metal is suitable, not only can the uneven distribution of deformation along the sheet metal be significantly improved, but the forming limit can also be increased, and the height of the protrusions can be reduced, reducing the margin of cutting. In addition, for some parts that are directly formed after material dropping, providing accurate sheet metal shapes and dimensions can reduce the number of trial mold adjustments, thereby shortening the production cycle and improving productivity.
4. When selecting materials for product design, avoid using high-grade materials that may result in excessive product performance. At the same time, while meeting product and process requirements, try to choose materials and thicknesses used in existing mass-produced models to form a material platform, providing convenience for subsequent procurement and inventory management. The key performance requirement for ordinary cold-rolled plates is their stretchability, so it is advisable to choose lower grade materials as much as possible while meeting the requirements of product quality. For the selection of material thickness, in addition to considering the strength and weight of the formed body, attention should also be paid to the popularization of material thickness. Due to the special thickness of the material, it is difficult for suppliers to supply and the price is also high.
