Sheet metal processing

Sheet metal processing steps include: sheet metal processing drawing design - laser processing or (CNC stamping) - bending - welding and forming - electrostatic powder spraying or (liquid paint) - packaging and shipping. First of all, sheet metal processing drawing design mainly refers to measuring, designing and developing according to the drawings or samples provided by customers, and then forming the processing breakdown drawing and assembly drawing and submitting them to the production department for processing. In sheet metal processing or laser processing, we can cut and cut carbon steel, stainless steel and other materials, and use laser cutting and cutting. After processing, the cross-section of the workpiece is neat, smooth and beautiful, and the size is accurate. It has more advantages for the workpiece with arc, and it is an irreplaceable processing method for general CNC punching. In addition, in the process of sheet metal numerical control stamping, at present, it is mainly aimed at some thin materials. Generally, the material below 2.5mm is suitable for the workpiece with more holes or special mold (such as convex and concave mold) to be processed. When the batch is large, CNC stamping has a certain cost advantage. In sheet metal processing, bending is also an indispensable part. Generally, after the workpiece is finished, it needs bending forming to provide good guarantee for subsequent welding and assembly.

In addition, in the process of sheet metal processing, welding forming has an important impact on product quality. Generally, the workpiece needs to be assembled and formed after blanking. There are many ways of assembly, some of which are directly formed by non welding processes such as screws and rivets. And the mechanical shell sheet metal is mostly welded to form, so that the workpiece is relatively firm and beautiful.
