Sheet metal processing products use epoxy mica iron intermediate paint, which is used in combination with epoxy zinc-rich primer as a durable anticorrosive coating transition layer. Its function is to enhance the sealing and corrosion resistance of the composite coating. It can be used as an anticorrosive and antirust primer, the coating film is strong, has good adhesion and sealing, and has good compatibility with the front and back coatings.
Its ingredients are: epoxy resin and curing agent, parent iron oxide and anti-rust pigment. This material is lighter in quality. Professional sheet metal processing is based on cold processing technology, so it has a relatively large compressive strength and is very hard. In addition, sheet metal belongs to steel and has very good electrical conductivity. And it has a very high cost performance compared to other steel processing methods.
To process CNC machining metal parts with good quality, it is necessary to strictly control the quality and fully understand the needs of customers. Sheet metal processing has small batches and many varieties. Newly developed products are easy to change. If the control is not good, quality problems are prone to occur. Therefore, you must understand customer requirements. When you come into contact with new varieties or new orders, you must have a certain understanding of the customer's sheet metal products, as well as understand the appearance, size requirements, and use of the sheet metal products.
For a long time, sheet metal chassis processing has become a more prominent form of processing in the processing industry. Nowadays, the housings of many electronic products are made of strong and long-life thin metal plates.
1. Finish the surface treatment of the workpiece after bending, riveting and other processes. For different boards, the surface treatment methods are different. After cold plate processing, the surface is usually plated. After plating, do not spray. Phosphate treatment first, and then spray. Clean and wipe off the grease on the surface of the board after degreasing.
2. Learn about the customer's requirements for the sheet metal machining, and choose different processes according to different customers' products. In the sheet metal chassis processing, usually after the blanking is completed, it enters the next process, and different workpieces enter the corresponding process according to the sheet metal processing requirements.
