for castings, steel castings, mechanical parts, etc. Sheet metal processing includes traditional laser cutting and blanking, blanking, bending and forming methods and main parameters of processing technology, structural characteristics of various cold dies and main parameters of processing technology, basic principles and processing methods of various facilities and new stamping processing technology and new technology applications. Nowadays, many electronic equipment enclosures are made of thin metal materials that are strong and have a long service life. So, what are the common problems in the main chassis of sheet metal processing?

1. after bending and riveting of sheet metal, carry out surface treatment of the product. For different plates, the surface treatment is different. After the cold-rolled steel plate is processed, the surface plating is usually carried out. No painting after plating process. Pickling and phosphating shall be carried out first, followed by painting. Clean and wipe off the vegetable oil on the surface of the woodworking board after deoiling.

2. in the processing of sheet metal automobile chassis, it is usually the blanking that goes to the next process, and different product workpieces go to the corresponding process according to the processing regulations.
