Issues to pay attention to when selecting materials for hardware stamping parts:
1. Among the specifications of steel plates, whether it is fixed-length plates or coils, the sales price varies with the same material and thickness but different coil widths. Therefore, to reduce costs, efforts should be made in determining the procurement coil width while ensuring material utilization. For fixed-length plates, it is advisable to choose appropriate specifications so that after cutting by the steel mill, no secondary cutting is needed, thus reducing cutting costs; for coils, it is best to select specifications and processes for uncoiling to reduce the workload of secondary cutting and improve work efficiency.
2. There are deviation requirements for the thickness of the plates. Usually, within the allowable range of deviation, plates with lower deviation should be selected first.
3. Determining the shape and size of the blanking material for stamping parts is a prerequisite for analyzing the degree of deformation of the stamping parts, designing process feasibility, and formulating process regulations. If the shape of the material is appropriate, it can significantly improve the uneven distribution of deformation along the material and also increase the forming limit, while reducing the height of the burrs and minimizing the cutting edge margin. Additionally, for certain parts that are directly formed after blanking, providing accurate shapes and sizes of the material can reduce the number of mold adjustments, thereby shortening the production cycle and improving productivity.
4. When selecting materials in product design, avoid using high-grade materials that lead to excessive product performance. At the same time, under the premise of meeting product and process requirements, try to choose materials and thicknesses used in existing mass-produced models to create a material platform, facilitating subsequent procurement and inventory management. For example, the key performance requirement of ordinary cold-rolled plates is their ductility, so it is advisable to choose lower-grade materials as long as they meet product quality requirements. Regarding the choice of thickness, in addition to considering the strength and weight after the body is formed, attention should also be paid to the popularity of the thickness. Special thicknesses are difficult for suppliers to provide, and they are also more expensive.
What issues should be considered when selecting materials for hardware stamping parts?
In the variety of steel plate specifications, whether it is a fixed-size plate or a coil plate, the sales price varies with different coil widths for materials of the same type and thickness. Therefore, to reduce costs, efforts should be made in determining the coil width during procurement, aiming to select a coil width range that does not incur additional charges while ensuring material utilization. For fixed-size plates, it is advisable to choose suitable specifications so that after cutting by the steel mill, no secondary cutting is required, thus reducing cutting costs; for coil plates, it is best to select specifications and processes for uncoiling that minimize the workload of secondary cutting and improve work efficiency.
