Precision hardware stamping parts are applied in various fields of our lives. What issues should we pay attention to when selecting precision hardware stamping materials
1、 In the standard types of steel plates, whether they are fixed length plates or rolled plates, materials with the same raw material and material thickness have different coil widths and sales prices. So, in order to reduce costs, it is necessary to focus on the development of procurement volume width, and try to choose a volume width range that does not increase prices while ensuring data utilization. Regarding the selection of suitable standard scales for the fixed length plate, it is recommended to cut it from the steel factory without the need for secondary cutting, in order to reduce the cutting cost; Regarding the rolling plate, try to choose the standard and process for uncoiling and forming the coil material, reduce the workload of secondary shearing, and improve work efficiency.
2、 The thickness of precision metal stamping plates has error requirements, and usually within the allowable range of error, the plate with the following error should be selected as the first choice.
3、 Confirming the shape and size of precision metal stamping open sheet metal is a prerequisite for analyzing the deformation degree of stamping parts, planning process performance, and formulating process procedures. If the shape of the sheet metal is appropriate, not only can the uneven distribution of deformation along the sheet metal be significantly improved, but the forming limit can also be improved, and the height of the lug can be reduced, reducing the trimming allowance. In addition, for certain parts that are directly formed after blanking, if precise sheet shape and scale can be provided, the number of trial mold adjustments can be reduced, and then the production cycle can be shortened to improve the production rate.
4、 When planning and selecting materials for precision metal stamping, it is important to prevent the use of high trademark raw materials that may result in excessive product functionality. On the premise of satisfying product and process requirements, it is best to select the raw materials and thicknesses used in existing mass-produced models to form a data platform, providing convenience for subsequent procurement and inventory management. The key functional requirement for cold-rolled sheets is their stretchability, so it is best to choose materials with low trademarks while meeting product quality requirements. Regarding 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 material thickness, it is difficult for suppliers to supply and the price is also high.
