Sheet metal, is for sheet metal a comprehensive cold working process, including shearing, punching, cutting, composite, folding, riveting, splicing, molding and so on.
Sheet metal is characterized by light weight, high strength, conductivity, low cost, and good mass production performance. As the application of sheet metal becomes more and more extensive, the design of sheet metal parts becomes a very important part of the product development process.
Main Uses
There are many sheet metal materials suitable for press processing, and the sheet metal materials widely used in the electronic and electrical industries include:
1. Ordinary Cold-Rolled Plate SPCC: SPCC refers to the ingot that is continuously rolled through the cold-rolling mill into coils or sheets with the required thickness.The surface of SPCC does not have any protection, and it is highly susceptible to oxidization when exposed to the air, especially in humid environments, which can cause oxidation. Especially in the humid environment oxidation speed up, the appearance of dark red rust, in the use of the surface to paint, plating or other protection.
2, galvanized steel SECC: SECC substrate for the general cold rolled steel coils, in the continuous zinc plating production line after degreasing, pickling, plating and a variety of post-treatment process, that is, to become the zinc plating products. SECC not only has the mechanical properties of the general cold rolled steel sheet and similar processability, but also has superior corrosion resistance and decorative appearance. In the market of electronic products, home appliances and furniture, SECC has great competitiveness and substitutability. For example, SECC is commonly used in computer cases.
