The development of the sheet metal processing industry is in increasing demand, which is also attributed to the rapid development of society and the popularity of high-tech products. Sheet metal processing is a very wide range of technology. Sheet metal products are characterized by light weight, high strength, electrical conductivity, low cost, and good mass production performance.
Sheet metal is a very wide range of technology, common products such as car shell, control box design, computer case and charging pile shell, etc. These are all sheet metal products. So if you want to apply it to the shell on the computer main case, how should the small heat dissipation hole be processed? For the processing of round holes in sheet metal processing, in terms of the common processing methods, the main ones are.
Laser cutting or plasma cutting if the thickness of the plate is less than 3mm.
Ordinary gas cutting or wire cutting. If the accuracy requirements are high, it is not recommended, because there is a possibility that the processing requirements can not be met.
Punching operation is performed, but it is usually used in large quantities, because the mold has to be opened. Therefore, if it is a single piece or small production, then it is not economical, so in this case, it will not come to use, and it is not recommended.
