Sheet metal box bending, also known as metal box fabrication, is often used to deform material to an angular one, which is one of the most important aspect of sheet metal forming bending. As one of the most experienced sheet metal box manufacturers, HSF fabrication supplies custom sheet metal boxes, which vary from aluminum sheet metal box to iron sheet box, sheet metal junction box, etc.

Surface treatment requires a sample or Pantone color number. Powder spraying: electrostatic spraying of powder coating, also known as spray coating. It uses a special electrostatic spray gun. After the paint is sent into the spray gun by means of compressed air, it is negatively charged near the corona discharge electrode of the electrostatic spray gun. Electrostatic force and dipole forces. Then, under the pressure of the conveying gas, the paint particles fly away from the spray gun and fly along the power line to the positively charged workpiece, and are arranged according to the distribution density of the surface power lines of the workpiece, so that the paint is firmly coated. On the surface of the workpiece.
