Heat dissipation hole of sheet metal shell

For the round hole processing in sheet metal processing, the common processing methods mainly include:

  1. Laser cutting or plasma cutting can be used if the thickness of the plate is less than 3mm.
  2. Ordinary gas cutting or wire cutting. If the accuracy requirements are relatively high, it is not recommended, because it may not meet the processing requirements.
  3. The punching operation is usually used in case of large quantity, because the die is to be opened. Therefore, if it is a single piece or small batch production, it is not economical, so in this case, it will not be used, and it is not recommended to use.
