Custom Battery Enclosure Manufacturer
The metal battery enclosure is one of the most important components of an energy storage battery project, providing effective protection and support for the integrated system of cells, thermal management system, battery management system (BMS), inverters, etc. It protects the cells from the risks of mechanical shocks, vibrations, and environmental erosion. Battery enclosure is the “bones and armor” that protects all components of the highly dangerous and costly energy storage battery system.
Typically, we use high-strength structural steel or stainless steel as the raw material for energy storage battery housings, to avoid damage from impact, compression, temperature and humidity, and corrosion caused by harsh environmental factors, to ensure stable operation of the internal system, and to increase the service life. However, there is still a need to keep battery housings lightweight and competitively cost-effective.
Battery enclosures have the same characteristics as other electrical enclosures, and it is very important to ensure excellent insulation to avoid the risk of electrical short circuits, which requires rational design of internal brackets and wire connectors.
We serve a wide range of industries worldwide in the manufacture of outdoor and indoor storage battery enclosures, providing enclosure designs that meet a wide range of use environments and functional requirements, including: NEMA 4 /3r IP66 or higher battery pack enclosure protection and IP55 or higher containerized storage battery enclosures, preventing dust ingress and withstanding strong water impacts or splashes, ensuring safe, reliable, and stable operation of storage batteries in a variety of harsh environments.

Provide a range of customized battery enclosure solutions.
With 20 years of experience in custom metal enclosure manufacturing, we understand the importance of weld integrity in outdoor battery enclosures to ensure that they meet the rigors of harsh environments and human-induced impacts, while maintaining a rugged overall structure that meets NEMA and IP protection ratings. We are adept at working with a variety of metals such as structural steel, alloy steel, cold rolled steel, stainless steel, hot rolled steel, and high mechanical performance aluminum alloys, which are bent, welded, and finished to achieve a foolproof, customized battery enclosure solution.

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

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.

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.

sheet metal bending services

We can manufacture exactly what is needed: angles, "U" shapes, multiple bent shapes, "C" shapes, etc., as well as all complex product designs. Provides the same dimensional and fit tolerance consistency, +/- .05mm accuracy on features or edges.
Supro MFG will always exceed your quality expectations.

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.
