Many high quality metal sheet fabrication parts use cold-rolled steel, which is specially used for sheet metal boxes. The sheet metal box parts should pay attention to protecting the threads during the spraying process, and the blockage caused by the electroplating process should be repaired by tapping. The threaded hole should be free from slippage and breakage, and the thread should be able to be screwed in smoothly and properly tightened. Insulation material selected according to the drawing, epoxy board or epoxy rod should be used as immersion insulation paint and dry.
If the cabinet of sheet metal box needs to be bent, it should be annealed before bending, and the radius of the bending angle should not be larger than the thickness of the plate material to avoid damage to the internal organization and cracking. The contact surface of the fastened connection must be flat. Where spray protection is required, parts of the sheet metal enclosure cannot be painted or powdered, the purpose of which is to ensure ground connection between parts.
