Professional Contract Manutacturing Services

Supro MFG combines a variety of sheet metal manufacturing equipment to provide a variety of different sheet metal bending and assembly molding services, with the skills and experience required to make your design a reality.

High quality sheet metal bending parts

Reasonable choice of materials

Material selection for electrical enclosures is critical, and common materials include high-quality cold-rolled steel, stainless steel, and aluminum alloys. These materials have good mechanical strength, corrosion resistance and processing performance. In the selection, according to the use of the environment (such as humid, corrosive environment) and design requirements (such as the level of protection) to determine the thickness of the material and material to ensure the durability and safety of the shell.

  • stainless steel :301 / 304 / 316 / 316L Etc.
  • Aluminum alloy : 6061 / 6063 / 5052 / 5754 / 5082 Etc.
  • Steel : Carbon Steel. Galvanized steel. Color coated steel, other steel.
  • Plastic : ABS / Acrylic / fiberglass / PC / PVC
design steel NEMA metal cabinets

Flexible structural design

The structural design of electrical cabinet housings needs to comply with electrical safety codes, meet high efficiencies for mass production, and be competitively cost-effective. Ensure adequate space layout to accommodate electrical components and facilitate post maintenance.

At the same time, we should consider the heat dissipation needs, reasonable design of ventilation holes and heat sink structure, to prevent overheating caused by equipment failure. According to different protection level requirements, rationally design the sealing and surface coating.

From simple rectangle to complex shaped structure, it needs to be accomplished through rich experience after continuous testing. For shells with special requirements, such as the need to increase the heat dissipation holes or mounting accessories, but also need to use punching, drilling and other processes to deal with.

sheet metal laser cutting services

laser cutting services

Laser cutting service is the most cost-effective cutting process.
Characterized by high precision and efficiency, it is able to accurately cut out the contour of the shell and reduce material wastage, while the CNC bending machine, according to a pre-set program, accurately bends the cut sheet to form the basic framework of the shell.

Supro MFG has two 6000KW high-precision laser cutting machines and one 12000Kw high-precision laser cutting machine, which can fulfill the requirement of cutting small quantities of sheet metal in one day.

Metal welding & Polishing fabrication services

At Supro MFG, the components of our customized electrical enclosures are joined together by welding techniques. For stainless steel or aluminum alloy enclosures, laser, TIG (Tungsten Inert Gas) or MIG/MAG (Melting Electrode Gas) welding is often used to ensure the aesthetics and strength of the weld. Cold rolled steel shells may be resistance welded or arc welded, depending on the specific needs of the choice.
After the welding is completed, it is also necessary to carry out weld grinding, stress relief treatment, etc., to ensure that the weld seam is flat, no cracks, while reducing welding deformation. Grinding removes slag and burrs and improves appearance.

surface treatment Services

In order to improve the corrosion resistance and aesthetics of the shell, surface treatment, such as electrostatic spraying, powder coating or anodizing, is usually required. These processes can form a layer of uniform, dense coating on the surface of the shell, effectively isolating the external environment.

Coating is the key link to enhance the protective performance of electrical cabinet shell. According to the design requirements, select the appropriate coating (such as epoxy paint, polyurethane paint, etc.), through spraying, dip coating and other ways to evenly cover the surface of the shell, forming a dense protective layer. During the coating process, it is necessary to pay attention to control the thickness and uniformity of the coating to avoid defects such as sagging and blistering.

Wide range of electrical enclosure accessories

We can provide you with a wide range of electrical enclosure accessories, whether non-standard or standard parts, including: hinges, bolts, seals, brackets, panels, viewing windows, cables, terminals, and more.

Assembly and Testing and Quality Control

Assembly is the final step in shell production and involves the precise installation of components such as door, side and top panels, as well as the fixing of accessories such as internal brackets and rails. The selection and installation of fasteners is critical in this process, both to ensure sufficient tightening force and to avoid deformation of the shell or damage to components caused by over-tightening.
After the assembly is completed, a series of tests need to be carried out, including insulation resistance test, voltage resistance test, protection level test, etc., in order to verify the overall performance and safety of the electrical cabinet shell. At the same time, it is also necessary to carry out an appearance check to ensure that the shell is free of scratches, dents and other defects.

Establishment of a perfect quality control system, every link in the production process is strictly controlled to ensure stable and reliable product quality. This includes raw material inspection, process control (such as first piece inspection, process inspection and finished product inspection, etc.) and performance testing and other aspects. At the same time, strengthen staff training, improve the skill level and quality awareness of production staff.
