Custom Metal Box Fabrication


Sheet metal box bending, also referred to as metal box fabrication, is a crucial process for shaping materials into angular forms—a fundamental aspect of sheet metal forming bending. HSF Fabrication, recognized as one of the most seasoned sheet metal box manufacturers, offers a range of custom sheet metal boxes. Our offerings span from aluminum sheet metal boxes to iron sheet boxes and sheet metal junction boxes.


The process involves bending aluminum sheets, with careful consideration given to the initial bending test, gap inspection, and post-surface treatment assembly evaluation. Subsequent steps include riveting injection, requiring a 160-degree oven temperature for plating, and silk screen printing of white words. Silk screen printing necessitates pre-prepared stencils and the use of customer-specified color inks.


As one of the most renowned custom metal box manufacturers and sheet metal box manufacturers in China, our expertise lies in custom aluminum box fabrication. Various sheet metal boxes are available for sale, presenting excellent choices for your needs. Customers can benefit from personalized services based on 3D drawings, samples, or detailed requirements. For further inquiries, feel free to leave a message or contact us. Trust HSJ for high-quality custom sheet metal boxes—the reliable supplier for your fabrication needs!


Custom Sheet Metal Box Fabrication Processes


Various procedures are involved in the fabrication of custom metal boxes through sheet metal box bending.


  • Processing Technology:

The fabrication process encompasses sheet metal fabrication, CNC laser sheet metal fabrication of sheet metal, bending, and welding.


  • Surface Treatment:

Surface treatment requires either a sample or a Pantone color number.


  • Powder Spraying:

One notable technique is electrostatic spraying of powder coating, commonly known as spray coating. This method involves the use of a specialized electrostatic spray gun. Compressed air transports the paint into the spray gun, where it becomes negatively charged near the corona discharge electrode. Electrostatic and dipole forces come into play. Pressurized conveying gas then propels the paint particles away from the spray gun, guiding them along the power line to the positively charged workpiece. The particles adhere to the workpiece's surface, forming a solid paint coating based on the distribution density of the surface power lines. This ensures a secure and even application of paint onto the workpiece.


Application of Sheet Metal Boxes


Applications of sheet metal box bending, namely,  bending sheet metal into a box, are wide. As one of the most professional custom metal box manufacturers, HSJ has earned rich experience in bending sheet metal boxes. Examples of formed metal parts we have produced include small sheet metal boxes, aluminum sheet metal enclosures, clamps, and mounting brackets, which are used in auto machinery, household item, medical equipment, electrical, etc.
