Power Supply & Battery Metal Enclosures for Industrial and OEM Electronics
Power supply and battery metal enclosures are used to protect power modules, battery packs, LED drivers, converters, and related electronic components. They are fabricated from metal sheets and are designed to provide mechanical protection, heat dissipation, and long-term durability for industrial, commercial, and OEM electronics.
As a manufacturer of power supply and battery metal enclosures, we produce metal enclosures for power supply units, battery enclosures, metal LED power supply housings, vented enclosures for electronic devices, and custom electronics enclosures according to customer drawings, samples, or project requirements.
For a broader overview of electronic enclosure materials, sheet metal fabrication processes, control equipment applications, and OEM production, you can also read our electronic metal enclosure manufacturer guide.
What Are Power Supply & Battery Metal Enclosures?
Power supply and battery metal enclosures are protective housings made from metal, designed to contain and protect electrical components and batteries. They also support proper heat dissipation, component installation, and wiring organization.
A custom metal power supply or battery enclosure may include:
- Custom size and thickness
- Cable entry holes and knockouts
- Ventilation slots or perforations
- PCB or component mounting points
- Battery or power module compartments
- Grounding points
- Hinged or removable covers
- Powder coated, anodized, or brushed metal finish
- Secure latches or locks
These enclosures are commonly used in industrial power supplies, battery systems, LED power modules, telecom devices, control equipment, and OEM electronics.
Materials for Power Supply & Battery Enclosures
Material selection affects durability, weight, heat dissipation, corrosion resistance, and surface finish.
Aluminum
- Lightweight and corrosion-resistant
- Suitable for industrial power modules and LED power supply housings
- Can be anodized, brushed, polished, or powder coated
Stainless Steel
- Strong and corrosion-resistant
- Suitable for outdoor, industrial, and harsh environments
- Brushed, polished, or passivated finishes
Carbon Steel
- Strong and cost-effective
- Suitable for industrial control units, power supply boxes, and OEM battery enclosures
- Usually powder coated or painted
Galvanized Steel
- Provides basic corrosion protection
- Suitable for industrial and OEM applications
- Can be powder coated for additional protection
Fabrication Process
Power supply and battery metal enclosures are fabricated using:
- Sheet Metal Cutting – laser cutting or punching to create precise openings for connectors, vents, and cable entries
- CNC Bending – forming the enclosure body, cover, or panels
- Welding and Assembly – joining parts, adding internal brackets or compartments
- Drilling, Tapping, and Hardware Installation – installing PEM nuts, screws, and grounding points
- Surface Treatment – powder coating, anodizing, brushing, or painting
- Quality Inspection and Packaging – ensuring dimension accuracy, surface finish, and assembly quality
Applications
Power supply and battery metal enclosures are used in:
- Industrial power supply units
- Battery packs and modules
- LED power modules
- Telecom devices
- Control equipment
- OEM electronics
- Instrumentation
- Automation systems
These enclosures protect components, improve heat dissipation, and support assembly and maintenance.
Choosing a Manufacturer
When selecting a manufacturer for power supply or battery enclosures, consider:
- Sheet metal fabrication and CNC bending experience
- Welding, assembly, and hardware installation
- Surface treatment quality
