ISO Automotive Hardware Metal Electronic Stamping Parts Corrosion Protection

Matters needing attention in material selection of metal stamping parts:

1. In the types of steel plate specifications, whether it is a cut-to-length plate or a coiled plate, the same 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 purchased roll width, and try to select a roll width range that does not increase the price under the premise of ensuring material utilization. For example, try to choose the appropriate specification and size for the cut-to-length plate. After the shearing from the steel factory, there is no need to perform secondary shearing to reduce the cost of shearing; Cut the workload and improve work efficiency.

2. There is a deviation requirement for the thickness of the plate, usually within the allowable range of the deviation, the plate with the lower deviation should be selected first.

3. Determining the shape and size of the unfolded sheet of the stamping part is the prerequisite for analyzing the degree of deformation of the stamping part, designing the manufacturability and drawing up the process regulations. If the shape of the sheet is suitable, 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 allowance can be reduced. In addition, for some parts that are directly formed after blanking, if the accurate shape and size of the sheet can be given, the number of times of mold trial and adjustment can be reduced, thereby shortening the production cycle and improving productivity.

4. When selecting materials for product design, avoid excessive product performance caused by high-grade materials. At the same time, on the premise of meeting product and process requirements, try to select materials and material thicknesses used in existing mass-produced models to form a material platform. Provide convenience for subsequent procurement and inventory management.
