Custom Electrical Enclosures Manufacturer
As a specialized electrical enclosures manufacturer, we provide end-to-end custom sheet metal fabrication for industrial OEMs, automation companies, and electronics manufacturers. From NPI prototypes to low-volume and regular repeat production, we deliver precision-engineered enclosures, cabinets, and chassis that protect your critical components.
Based in Dongguan, China, with over 55% of our products exported to North America, Europe, and Australia, we are an engineering-responsive partner built on reliable quality, flexible volumes, and clear English communication.
Why Choose Us for Your Enclosure Projects?
We understand the pain points procurement teams, mechanical engineers, and quality managers face: slow RFQ responses, inconsistent cosmetic quality, and fragmented supply chains. We solve these challenges by offering:
Fast DFM & Engineering Support
We don't just cut metal; we provide fast engineering reviews and Design for Manufacturing (DFM) feedback to ensure your enclosures are cost-effective and structurally sound.
One-Stop Fabrication
Stop managing multiple vendors for a single assembly. We handle cutting, bending, welding, hardware insertion, and final assembly.
Prototype-to-Production Continuity
With an MOQ of 1 piece, we support your initial NPI builds (3–12 days) and seamlessly scale to regular production batches (15–25 days).
Export-Ready Communication
Responsive, clear English communication with dedicated project management.
Complete Manufacturing Capabilities
Whether you need a compact NEMA-rated wall-mount box, a complex server chassis, or a large industrial control cabinet, our 3,500 m² ISO 9001:2015 certified facility is equipped to deliver.
1. Precision Cutting & Punching
- Fiber Laser Cutting: Five machines (up to 2000 × 4000 mm) cutting stainless steel (up to 20mm), carbon steel (up to 25mm), and aluminum (up to 16mm) with ±0.10 mm tolerances.
- CNC Punching: Precision holes, ventilation louvers, and specialized formed features quickly and accurately.
2. CNC Bending & Forming
Seven CNC press brakes (capacity up to 230T / 3000 mm) ensure precise angles and tight seams for complex enclosure geometries, holding tolerances of ±0.20–0.30 mm.
3. Welding & Assembly
- Welding: TIG, MIG/MAG, Laser, and Spot welding for robust, leak-proof enclosure frames and seams.
- Hardware Insertion: PEM fasteners, standoffs, grounding studs, riveting, and M2–M12 tapping for PCB mounting and electrical grounding.
- Finishing Touches: In-house deburring, grinding, brushing, and basic polishing for safe edges and a premium foundation for coatings.
Materials Suited for Any Environment
We stock and process a wide range of sheet metal (typically 0.5–12 mm) suited for indoor electronics or harsh outdoor industrial environments:
-
Steel (SPCC/CRS, Q235/Q355, SGCC/SECC): Cost-effective, rigid, and ideal for powder-coated indoor control cabinets.
-
Stainless Steel (SUS304, SUS316, SUS430): Perfect for food-grade, medical, or marine-grade weatherproof enclosures.
-
Aluminum (5052, 6061, 5754): Lightweight with excellent heat dissipation for electronics and aerospace applications.
-
Copper (C1100/T2) & Brass (H62): Used for internal busbars, grounding plates, and specialized conductive shielding.
Surface Finishing & Cosmetics
Electrical enclosures require durable, high-quality finishes for both protection and branding. Through our network of rigorously qualified finishing partners, we provide:
-
Powder Coating: Durable, electrically insulating, and available in custom RAL colors (smooth, textured, or sand finishes).
-
Anodizing & Plating: For corrosion resistance and conductivity management.
-
Screen Printing & Laser Marking: For clear, permanent labeling of control panels, safety warnings, and company logos.
Note: While fabrication is done wholly in-house, all specialized surface treatments are managed through our trusted, quality-controlled local partners.
Uncompromising Quality & Documentation
As a trusted electrical enclosures manufacturer for global OEMs, we know that documentation is just as important as the physical part. Our QMS is ISO 9001:2015 certified, featuring a strict IQC, FAI, IPQC, FQC, and OQC flow.
Our inspection lab utilizes CMMs, 2.5D vision systems, and height gauges. We provide comprehensive documentation upon request, including:
FAI Reports
Dimensional Reports
Material Certificates
RoHS / REACH Docs
Coating & Finish Reports
