What are the main aspects of sheet metal chassis processing?

　　Sheet metal chassis processing methods mainly include the following aspects:

　　1. Laser cutting

　　Laser cutting is the best choice for cutting sheet metal chassis. It is a very fast and precise cutting method that ensures good results. For thicker chassis cabinet materials, plasma cutting can also be used, but laser cutting quality is better.

　　2. Mechanical cutting

　　Shearing or die cutting in the process of sheet metal chassis processing refers to the process of cutting sheet metal without burning or melting it. It is essentially not much different from cutting clothes with scissors. During the shearing process, the punch presses the workpiece against a fixed die or blade, and the gap between the two prevents the workpiece from passing through, thus completing the shearing.

　　3. Stamping

　　Stamping is another method of cutting holes in sheet metal chassis processing. It uses a metal punch to punch holes in the sheet. It is suitable for large-scale production, but it is not very cost-effective for small-scale production.

　　4. Bending

　　Due to the complexity of bending, this may be a more difficult step in the sheet metal chassis processing and manufacturing process. Engineers must be very familiar with the bending properties of metal. Most bending machines have certain restrictions on bending:

　　Single-side height: the size of the bending machine and the height of the upper knife. The solution can be multi-sided large-angle bending.

　　Double-side height: not greater than the maximum height of a single side. In addition to all the restrictions on the single-side height, it is also restricted by the bottom edge, that is, the bending height < the bottom edge.

　　5. Assembly

　　The assembly of the sheet metal chassis is usually the last or penultimate step in the completion of the product. If the assembly includes a welding process, it is necessary to ensure that the parts of the sheet metal chassis are clean. If the parts have been powder-coated, other methods such as riveting and bolting are usually used for assembly.

　　6. Powder coating (surface treatment)

　　Powder coating in sheet metal chassis processing is the process of applying electrostatic powder to charged metal parts. When there are no special requirements (such as acidic environments), it is a very suitable surface treatment method.

　　To sum up, we can see that the main processing methods of sheet metal chassis include laser cutting, mechanical cutting, stamping, bending, assembly, powder coating (surface treatment) and other methods. By doing a good job in these aspects, we believe that we can process and produce very good sheet metal chassis products.
