Custom Precision-Crafted 400mm Aluminum Enclosures

Nowadays, it is where precision engineering and rapid prototyping define industrial success, Zhonglian Aluminum reaffirms its leadership in custom aluminum solutions with the launch of our advanced 400mm aluminum enclosure series. With over 32+ years of extrusion expertise and vertically integrated manufacturing capabilities, we deliver seamless end-to-end services - from mold design to CNC-machined perfection - tailored to meet the most demanding technical specifications.

1. Engineered for Complexity, Built for Durability

Our 400mm enclosures are precision-extruded using ISO-certified 6063-T5/T6 alloys, optimized for structural rigidity and corrosion resistance. With ±0.15mm dimensional tolerance control and wall thickness uniformity exceeding ASTM B221 standards, these enclosures withstand harsh industrial environments while maintaining aesthetic integrity.

2. Integrated Manufacturing Ecosystem

· Custom Mold Development: 48-hour rapid mold prototyping with DFM analysis to eliminate design flaws.

· High-Tonnage Extrusion: 1,800-3,600T presses ensure grain structure consistency for large-profile stability.

· Advanced CNC Machining: 5-axis milling centers achieve Ra 0.8μm surface finishes with ±0.05mm positional accuracy.

· Premium Surface Treatments: Anodizing (AA-M12C22A41), powder coating (QUALICOAT Class 2), or electrophoretic finishes per MIL-A-8625.

3. Cross-Industry Application Mastery

· Industrial automation control cabinets

· Renewable energy inverter housings

· Medical imaging equipment chassis

· Telecom infrastructure shielding units

1. As your one-stop solution for both design, manufacturing, surface finishing, and CNC service of your custom aluminum profile, save time and ensure quality.

2. We can produce aluminum profiles in a wide range of sizes, especially the production of super-sized over 400MM is beyond the reach of most suppliers.

3. We have 600 tons to 5000 tons of advanced aluminum profile extrusion equipment, anodic oxidation lines, electrophoretic coating lines, and powder spraying.

For OEMs requiring mission-critical aluminum enclosures that balance precision, scalability, and supply chain transparency, our 400mm solution represents the nexus of engineering excellence. Zhonglian Aluminum full-service model eliminates vendor fragmentation risks while ensuring IP protection throughout production.
