Energy & EV Equipment
Energy & EV Equipment Sheet Metal Fabrication Services
Rapidsheetfab is an ISO 9001:2015 certified custom sheet metal fabrication manufacturer in Dongguan, China, supporting energy equipment and EV industry OEMs from one-piece prototypes and NPI builds through low-volume and repeat production.
We focus on engineering responsiveness, controlled quality, and export-ready communication—ideal for projects that require reliable dimensional/cosmetic consistency and documentation.
Request a QuoteWhat We Make for Energy & EV Equipment
We commonly fabricate a wide range of components for the energy and EV sector:
- EV charging equipment enclosures (AC chargers, DC fast chargers, wallbox housings)
- Battery equipment housings and structural sheet metal (non-cell-contact parts)
- Power electronics chassis and frames (inverters, converters, rectifiers, PDU housings)
- Industrial cabinets and control boxes for energy storage systems (ESS/BESS auxiliaries)
- Panels, brackets, mounting plates, and heat-shield parts
- Welded sub-assemblies with threaded hardware and captive fasteners
If your RFQ includes a prototype phase and a path to repeat builds, we are a strong fit.
Manufacturing Capabilities (Prototype to Production)
Our 3,500 m² facility supports multi-process builds so you can reduce supplier count for assemblies.
Cutting & Forming
- •Fiber laser cutting (5 units), sheet capacity up to 2000 × 4000 mm
- •CNC press brakes (7 units) up to 230T / 3000 mm
- •CNC punching for precision holes, louvers, and formed features
Welding & Assembly
- •TIG, MIG/MAG, laser welding, and spot welding
- •PEM hardware insertion, riveting, and M2–M12 tapping
- •Deburring, grinding, brushing, basic polishing, and assembly support
Typical Tolerances
- •Laser cutting: ±0.10 mm
- •Bending: ±0.20–0.30 mm
- •Holes: ±0.10–0.20 mm
Drawing-dependent tolerances.
Materials & Finishing Options
We support a broad set of metals used in charging, storage, and power electronics equipment:
- Stainless steel: SUS304, SUS316, SUS430
- Steel: SPCC/CRS, Q235/Q355, SGCC/SECC
- Aluminum: 5052, 6061, 5754
- Copper C1100/T2 and brass H62
Typical sheet metal thickness range: 0.5–12 mm
Laser cutting capacity: stainless up to 20 mm, carbon steel up to 25 mm, aluminum up to 16 mm.
Energy and EV equipment often requires controlled cosmetics and corrosion resistance. We can coordinate:
Note: These finishing processes are provided through qualified finishing partners and should not be considered wholly in-house operations.
Quality Control & Documentation
We support export-ready quality requirements and supplier quality expectations:
Quality flow: IQC → FAI → IPQC → FQC → OQC
Inspection equipment: CMM, 2.5D vision, height gauges, and standard tools
Documentation available:
- •First Article Inspection (FAI)
- •Dimensional inspection reports
- •Material certificates
- •RoHS/REACH documents
- •Coating reports (when applicable)
This is especially useful for NPI validation, pilot runs, and ongoing supplier performance tracking.
Lead Time & Export Service
- •MOQ: 1 piece for prototypes
- •Prototype lead time: 3–12 working days (process-dependent)
- •Small batch: 10–15 days
- •Regular production: 15–25 days
Export experience: Direct overseas support since 2019, ~55% export sales
Main markets: US, Canada, Germany, UK, Netherlands, Sweden, Australia, Singapore
