Discover how custom industrial equipment enclosures are engineered for protection, accessibility, and thermal performance. Learn about real projects and fabrication techniques used at Fulei Metal.
Introduction
Industrial equipment enclosures protect sensitive electronics, controllers, and machinery from environmental hazards while providing safe access for operation and maintenance. These enclosures range from small wall-mount boxes to large floor-standing cabinets housing complete control systems. At Fulei Metal, we fabricate equipment enclosures for diverse industries including automation, telecommunications, energy, and manufacturing.
Enclosure Design Principles
The first consideration in enclosure design is the operating environment. Indoor industrial environments typically require IP54 or IP55 protection against dust and dripping water. Outdoor environments demand IP65 or IP66 for resistance to rain and water jets. Equipment enclosures must provide access for installation, operation, and maintenance. We design doors with adequate clearance for the largest internal components, position control panels at ergonomic heights, and include internal lighting where needed.
Enclosures housing sensitive electronics may require electromagnetic interference (EMI) shielding. We achieve this through continuous welded seams, conductive gaskets, and filtered cable entries. Our welding team is experienced in producing continuous seam welds that maintain electrical continuity around door openings and panel joints.
Material Selection
Cold-rolled steel (SPCC) is the standard material for indoor equipment enclosures, with wall thickness ranging from 1.2 to 2.5 mm. For food processing, pharmaceutical, marine, and outdoor applications, stainless steel enclosures provide superior corrosion resistance. Grade 304 is suitable for most environments, while grade 316L is recommended for coastal or chemical environments. Aluminum enclosures offer weight savings and natural corrosion resistance, ideal for portable equipment and aerospace applications.
Fabrication Process
Our TRUMPF fiber laser cuts all enclosure panels from flat sheet stock, producing clean, accurate cutouts for connectors, displays, ventilation slots, and mounting features. Four CNC press brake machines form enclosure panels with precise bends, with back-gauge accuracy ensuring consistent dimensions across production batches. Our ten welding stations handle TIG, MIG, and resistance spot welding. Surface treatment options include powder coating, liquid painting, anodizing, and plating.
Our assembly team installs hinges, locks, gaskets, fans, filters, internal mounting plates, and grounding hardware. For clients requiring turnkey solutions, we also install client-supplied electronic components, wiring, and cable management systems. Each assembled enclosure undergoes functional testing before packaging.
Case Study: Automation Equipment Enclosures
A German automation company needed custom enclosures for a new line of robotic controllers. The enclosures required IP65 protection, EMI shielding, forced-air cooling, and a specific RAL color to match their corporate identity. We fabricated 300 enclosures from 1.5 mm cold-rolled steel with continuous welded seams, conductive gaskets, integrated fan systems, and a custom-textured powder coat finish. The client has since ordered two additional production batches and expanded the enclosure line to include three additional sizes.
Conclusion
Industrial equipment enclosures are complex products that require integrated design, fabrication, and assembly capabilities. Fulei Metal’s comprehensive manufacturing process ensures that clients receive enclosures meeting their exact specifications for protection, functionality, and appearance.
