Product Overview
A sheet metal cabinet is an enclosure fabricated from cold-rolled steel, stainless steel, or aluminum sheets. It houses electrical components, industrial controls, telecommunications equipment, or general storage, providing mechanical protection, EMI shielding, and environmental sealing.
Unlike injection-molded plastic enclosures, sheet metal cabinets offer superior strength, heat dissipation, and customizability — making them the preferred choice in power distribution, server rooms, factory automation, and outdoor installations.
At Jiafeng, every cabinet is engineered from design drawings through final assembly, with in-house sheet metal manufacturing capabilities including fiber laser cutting, CNC press brake bending, and robotic MIG/TIG welding.
Key Capabilities
How We Build It
From raw coil to finished cabinet, our streamlined 8-step process guarantees dimensional accuracy, structural integrity, and aesthetic consistency at every production stage.
3D modeling in SolidWorks/AutoCAD; DFM review to optimize sheet utilization and bend sequences.
6,000 W fiber laser cuts blanks to ±0.1 mm tolerance — no burrs, no secondary deburring needed.
Press brake forming with angle accuracy ±0.5°; multi-bend complex profiles produced in one setup.
CNC turret punching for ventilation slots, cable entries, and mounting holes; PEM stud insertion.
Robotic MIG and manual TIG welding for structural seams; weld grinding to Ra ≤ 1.6 µm.
Degreasing, phosphating pretreatment, then powder coating (RAL palette) or galvanizing / anodizing.
Hinges, locks, cable management, DIN rails, and optional electromechanical components installed.
Dimensional check, IP ingress test, coating adhesion test, and final inspection before export packing.

FAQ
We accept STEP, IGES, SolidWorks (.SLDPRT/.SLDASM), AutoCAD (.DWG/.DXF), and PDF engineering drawings. If you only have a sketch or concept, our engineering team can create production drawings for you as part of our OEM/ODM service.
Our MOQ is 1 piece for prototypes and samples. For volume orders, pricing tiers typically begin at 50 pieces. We welcome both small R&D orders and large-scale mass production contracts.
Yes. We fabricate sheet metal cabinets with IP54, IP65, and IP66 ratings using precision-formed door flanges, foam or silicone gaskets, and gland plate entries. IP67/IP68 solutions are available on request with upgraded sealing systems.
Absolutely. In addition to powder coating (full RAL palette), we offer hot-dip galvanizing, electro-galvanizing, electroless nickel plating, anodizing (for aluminum), brushed finish, and chrome plating. The right choice depends on the environment and aesthetic requirements of your application.
We operate a three-stage QC system: Incoming Quality Control (IQC) on raw materials, In-Process Quality Control (IPQC) at laser cutting, bending, and welding stages, and Outgoing Quality Control (OQC) including dimensional inspection, coating adhesion cross-cut test, and IP ingress verification before shipment.
Prototypes and samples are typically delivered in 7–15 business days after drawing approval. Standard production orders take 20–30 days depending on complexity and quantity. Rush production in 5–7 days is available for urgent requirements.
