How does Dongguan metal stamping factory solve the problem of surface damage in stamping-hardware

In production, when the Dongguan Hardware Stamping Factory performs continuous bending operations on soft materials such as copper and aluminum alloys, metal particles or scum are easy to attach to the surface of the working part, causing large scratches on the parts, and then scratches. When the bending direction is parallel to the rolling direction of the material, cracks will occur on the surface of the workpiece, which will reduce the surface quality of the workpiece. When bending at two or more places, as much as possible to ensure that the bending direction and the rolling direction have a certain angle; the corner radius of the die is too small, and impact marks appear in the bending part. Polish the concave mold and increase the radius of the corner of the concave mold to avoid scratches on the curved parts; the gap between the convex and concave molds should not be too small, and the gap is too small to cause thinning and scratches. During the stamping process, always check the change of the gap of the mold; when the punch enters the concave mold too deeply, the surface of the part will be scratched. Therefore, the punch should be appropriately reduced while ensuring that it is not affected by springback. Enter the depth of the die; hardware, 15 years of craftsmanship focusing on the stamping industry, more than 20 Ru0026D and design projects, 20,000+ sets of mold customization processing and production experience, 3 million punching times per day, 16 quality inspections strictly for quality control.
