The scratches on the surface of precision metal stamping parts are mainly due to the relative movement between the workpiece and the mold surface. Under the action of a certain pressure, the blank and the local surface of the mold directly generate friction. In addition, the deformation heat of the blank causes the blank and metal chips to deposit on the mold surface, and the scratch on the surface of the workpiece.

Automotive precision stamping parts are metal stamping products used in automobiles. Supports, end covers, covers, spring seats, dust covers, etc. belong to automotive precision stamping parts, with a wide variety of products, and high requirements for surface quality, rigidity and dimensional accuracy.

In the steel plate specification category, whether it is fixed length plate or coiled plate, the same material and material thickness have different coil widths and different sales prices. Therefore, in order to reduce the cost, it is necessary to work hard on the formulation of the procurement roll width, and try to select the roll width range without price increase on the premise of ensuring the material utilization rate.
