ISO 9001:2015 Certified Manufacturer
Electronics & Electrical Sheet Metal Fabrication Services
Rapidsheetfab is a custom sheet metal fabrication manufacturer in Dongguan, China. We support electronics and electrical OEMs with engineering-responsive fabrication—from one-piece prototypes and NPI builds to low-volume and repeat production—with export-ready quality documentation and clear English communication.
What We Make for Electronics & Electrical OEMs
We manufacture custom sheet metal parts and assemblies commonly used in electronics and electrical equipment, including:
Electrical Enclosures & Housings
Indoor/outdoor concepts, panels, doors, and covers built to your specifications.
Chassis & Frames
For instruments, controllers, and embedded systems requiring structural rigidity.
19-Inch Rack Components
Rack-mount panels, mounting plates, and related hardware for standard rack systems.
Brackets, Trays & Supports
Precision components for PCBs, power supplies, sensors, and electronic modules.
Control Cabinets
Sub-assemblies requiring bending, welding, and hardware integration in one build.
Panels & Welded Assemblies
Precision cutouts for switches, displays, connectors, and vents, plus multi-part welded builds.
If your RFQ includes both prototype and follow-on production quantities, we are structured to support continuity from the start.
Capabilities Built for Electronics & Electrical Requirements
Cutting, Forming, and Feature Creation
- Fiber laser cutting — sheet size up to 2000 × 4000 mm
- CNC punching — precision holes, louvers, and formed features
- CNC press brakes — up to 230T / 3000 mm for repeatable bending
Typical drawing-dependent tolerances:
Laser Cutting
±0.10 mm
Bending
±0.20–0.30 mm
Holes
±0.10–0.20 mm
Welding and Assembly
- Welding processes — TIG, MIG/MAG, laser welding, and spot welding
- Hardware integration — PEM hardware insertion, riveting, and M2–M12 tapping
- Finishing prep — deburring, grinding, brushing, basic polishing, and assembly
These processes support common electronics assembly needs such as consistent hardware alignment, strong joints, and clean edges suitable for handling and finishing.
