Battery Enclosures Manufacturer
Rapidsheetfab is a battery enclosures manufacturer specializing in custom sheet metal battery enclosures for industrial OEMs—supporting projects from one-piece prototypes and NPI builds through low-volume and repeat production. Founded in 2015 and located in Dongguan, China, our 3,500 m² facility is set up for engineering-responsive fabrication, controlled quality, and export-ready communication.
If you need a supplier that can move quickly on prototypes while maintaining the process control required for production continuity, we are built for that workflow.
Battery Enclosures We Manufacture
We fabricate custom sheet metal components and assemblies commonly used in battery and power systems, such as:
- Battery enclosures and housings
- Battery cabinets and floor-standing enclosures
- Battery trays and mounting bases
- Brackets, frames, and structural supports
- Covers, access panels, and service doors
- Welded assemblies with PEM hardware and tapped holes
- Sub-assemblies prepared for customer final integration
Typical application industries include industrial equipment, automation, robotics, electronics/instruments, energy equipment, machinery, and laboratory/medical equipment.
Prototype-to-Production Support
Many battery enclosure programs start with an enclosure prototype, then move into small batch builds. We support this progression with:
1 Piece for Prototypes
No minimum quantity barrier to start your project.
Prototype Lead Time
Typically 3-12 working days, depending on process.
Small Batch Lead Time
Typically 10-15 days for small batch builds.
Production Lead Time
Regular production typically 15-25 days.
Engineering review and DFM feedback included to reduce rework in later builds.
Sheet Metal Fabrication Capabilities
Our in-house processes support enclosure builds that require more than cutting and bending:
Fiber Laser Cutting
5 machines, sheet capacity up to 2000 x 4000 mm
CNC Press Brakes
7 machines, up to 230T / 3000 mm
CNC Punching
Precision holes, louvers, and formed features
Welding
TIG, MIG/MAG, laser welding, spot welding
Hardware Insertion
PEM hardware, riveting, M2-M12 tapping
Finishing & Assembly
Deburring, grinding, brushing, polishing, assembly
Materials for Battery Enclosures
We regularly fabricate battery enclosures using:
SUS304, SUS316, SUS430
SPCC/CRS, Q235/Q355, SGCC/SECC
5052, 6061, 5754
C1100/T2 and brass H62 for specific conductive or accessory parts
Typical sheet metal thickness range: 0.5-12 mm
Laser cutting capacity: stainless steel up to 20 mm, carbon steel up to 25 mm, aluminum up to 16 mm
Tolerances & Process Capability
For battery enclosure programs, we communicate capability clearly based on geometry, material, thickness, and inspection method. Typical reference capabilities include:
If you have gasket interfaces, alignment features, door fit-up requirements, or critical hole patterns, share your functional requirements and we will review them during quoting.
Surface Finishing Options
Battery enclosures often require corrosion protection, cosmetic consistency, and marking. We can arrange:
Note: Surface finishing is provided through qualified finishing partners and should not be considered wholly in-house.
Quality Control & Inspection
Battery enclosure builds typically require traceability and measurable quality. Our quality flow includes IQC, FAI, IPQC, FQC, and OQC, supported by:
- CMM inspection
- 2.5D vision measurement systems
- Height gauges and standard inspection tools
Documentation available upon request:
- First Article Inspection (FAI)
- Dimensional inspection reports
- Material certificates
- RoHS/REACH documents
- Coating reports (from finishing partners)
Quality management system: ISO 9001:2015 certified
Export Support for Industrial OEMs
We have provided direct overseas service since 2019, with ~55% export sales. Common markets include the United States, Canada, Germany, the United Kingdom, the Netherlands, Sweden, Australia, and Singapore.
You can expect clear, responsive English communication for:
- RFQ clarification and engineering review
- Inspection and documentation requests
- Packaging requirements and shipment coordination
