Electronics Enclosures Manufacturer
Prototype to production sheet metal enclosures, chassis, cabinets, and assemblies—built for industrial OEMs.
Rapidsheetfab is a custom sheet metal fabrication manufacturer founded in 2015 in Dongguan, China. We support industrial OEMs with electronics enclosures and related fabricated parts—from one-piece prototypes and NPI builds through low-volume and repeat production—with responsive engineering support, controlled quality, and export-ready communication.
Note on finishing: powder coating, anodizing, plating, passivation, sandblasting, electropolishing, screen printing, and laser marking are provided through qualified finishing partners and should not be interpreted as fully in-house processes.

- • Laser cutting tolerance typically ±0.10 mm (drawing-dependent)
- • CNC punching for holes, louvers, and formed features
Bending & Forming
- • 7 CNC press brakes, up to 230T / 3000 mm
- • Typical bending tolerance ±0.20–0.30 mm (drawing-dependent)
Welding & Joining
- • TIG, MIG/MAG, laser welding, and spot welding
- • Riveting, tapping M2–M12
- • PEM hardware insertion for studs, nuts, standoffs
Deburr & Assembly
- • Deburring, grinding, brushing, basic polishing
- • Assembly support for multi-part enclosures and kits
