Sheet metal has the characteristics of light weight, high strength, conductivity, low cost and good mass production performance. With the wider application of sheet metal parts, the design of sheet metal parts has become a very important part in the product development process.
Main applications
There are many sheet metal materials suitable for stamping. The sheet metal materials widely used in the electronic and electrical industry are:
1. Ordinary cold-rolled plate SPCC:SPCC refers to the continuous rolling of steel ingots into coils or steel plates with required thickness by cold rolling mill. The surface of SPCC is unprotected, and it is easy to be oxidized when exposed to air, especially in humid environment, the oxidation speed is accelerated and dark red rust appears. When in use, the surface should be painted, electroplated or otherwise protected.
2. Galvanized steel plate SECC: The base material of SECC is common cold-rolled steel coil, which becomes an electro-galvanized product after degreasing, pickling, electroplating and various post-treatment processes on the continuous electro-galvanized production line. SECC not only has the mechanical properties and approximate machinability of common cold-rolled steel plates, but also has excellent corrosion resistance and decorative appearance. It has great competitiveness and substitution in the markets of electronic products, household appliances and furniture. For example, SECC is widely used in computer chassis.
