Custom OEM Metal Enclosures | Excelsior Hardware
Excelsior Hardware & Plastic Co., Ltd. designs and manufactures precision sheet metal electronic enclosures, metal enclosures, and custom metal enclosure box solutions engineered specifically for professional audio, broadcast, and industrial electronics. Every metal enclosure we ship is built around your exact PCB layout, connector placement, and operational environment. This one-to-one engineering approach ensures the metal enclosure box you receive is not just a housing—it’s an integral part of your product’s performance and reliability.
Precision Engineering for Pro Audio Housings
In professional audio, the chassis directly influences electromagnetic compatibility, thermal behavior, and user experience. Consider our widely adopted CNC audio remote decoder metal enclosure box: it starts with 1.2mm SECC cold-rolled steel, formed on high-precision CNC press brakes and laser-welded at critical seams. Corner gussets increase torsional rigidity by 40% compared to a standard fold-only design. The front and rear panels—key elements in any sheet metal electronic enclosures project—are machined to ±0.05mm accuracy, guaranteeing flawless fit for USB, SD card slots, XLR jacks, and indicators without post-assembly trimming. This attention to detail in our metal enclosures directly extends insertion-cycle life and shields sensitive circuits from interference.
Protection & Certifications at a Glance
Specification | Detail |
Ingress Protection | IPX5 water-resistant (sustained low-pressure jetting) |
EMC Compliance | Conforms to EN 55032 / EN 55035 |
Environmental | RoHS 2.0 & REACH compliant |
Salt Spray Resistance | ≥ 500 hours (black texture powder coat) |
Flammability Rating | UL 94-V0 equivalent (insulating components) |
Every metal enclosure box leaves our facility after a full IPX5 spray test, confirming reliable operation in outdoor events, mobile broadcast vans, and humid indoor environments. For applications demanding enhanced EMI shielding, our sheet metal electronic enclosures can be fitted with conductive foam gaskets or beryllium-copper spring fingers along mating seams, achieving shielding effectiveness above 60 dB in key frequency ranges.
Manufacturing Process in Depth
Excelsior divides the production of metal enclosures into four tightly quality-gated stages:
1. Precision Cutting & Forming
A Trumpf laser cutting system slices sheet metal with ±0.1mm edge accuracy. Blanks then pass through CNC press brakes with angle tolerance held to ±0.5°, guaranteeing uniform assembly gaps on the final metal enclosure box.
2. Robotic Welding & Finishing
Panasonic robotic cells execute continuous welds on critical joints of sheet metal electronic enclosures. Post-weld grinding and graining erase visible weld seams, merging structural strength with aesthetics.
3. Surface Treatment
The standard black textured powder coat (60–80µm film) withstands over 500 hours of neutral salt spray. We also offer anodizing, electrophoretic coating, and liquid painting, giving your metal enclosures the exact surface feel your brand requires.
4. Silkscreen & Pre-assembly
Imported UV-resistant inks print logos, port labels, and warning symbols onto the metal enclosure box. Adhesion reaches 5B (cross-cut test). Hardware, inserts, and fasteners are then pre-fitted so the metal enclosure arrives ready for immediate board mounting.
Applications Across Industries
Our sheet metal electronic enclosures and metal enclosure box products serve demanding sectors:
- Recording & Broadcasting –Shielded, well-ventilated metal enclosures for DSP processors and AD/DA converters, reducing digital noise.
- Live Sound & Touring –Rugged metal enclosures for wireless microphone receivers and DI boxes, built with thick gauge steel and vibration-resistant mounts.
- Commercial Audio Installations –Wall-mount or rack-mount sheet metal electronic enclosures for constant-voltage amplifiers and zone controllers, with pre-stamped conduit knockouts.
- OEM Equipment Integration –Fully bespoke metal enclosure box designs, including non-standard footprints, odd-shaped cutouts, and multi-module stacking structures.
Flexible OEM/ODM Collaboration
Service Tier | Turnaround | Best For |
CNC Prototype | 3–5 days, no tooling | Design verification, fit testing |
Low-Volume Production | 10–500 units, CNC-based | Market trials, niche products |
Mass Production | 15–20 days with progressive tooling | Stable demand, cost reduction |
Whether you need one metal enclosure box for a proof-of-concept or thousands of sheet metal electronic enclosures for a product launch, our process scales smoothly. All metal enclosures can carry your custom silk-screen logo, bespoke packaging, and optional drop-test reports.
Global Quality & Delivery
Manufactured under ISO 9001:2015 controls, every batch of metal enclosure box units is traceable from raw material certificates to final inspection. Based in Guangdong, China, with reliable global logistics partners, Excelsior exports sheet metal electronic enclosures and metal enclosures steadily to North America, Europe, and Southeast Asia.
