Aluminum Profile Solutions for Smart Logistics System: Precision & Efficiency

As a leader in the new retail industry, Boxa (Freshippo) is committed to building an efficient and intelligent logistics distribution system. The core component of this system is the smart conveyor system, which relies heavily on aluminum profiles for its structural integrity and precision. These profiles are critical for ensuring smooth operation and long-term reliability in automated sorting and material handling processes.

????️ Technical Challenges

1. High Precision Requirements
   The conveyor system must operate seamlessly along complex curved tracks, requiring exceptional flatness, curvature consistency, and joint gap control.

2. Long-Length Bending
   Some sections of the conveyor extend over 6 meters, necessitating single-piece extrusion to avoid welding-induced errors.

3. Cleanliness and Hygiene Standards
   The system must meet food-grade cleanliness standards, demanding surface treatments free from micro-particles and easy to clean.

???? Our Solution

Dunpin Aluminum, with over 20 years of expertise in industrial aluminum extrusion and precision processing, provided tailored solutions for Boxa's smart logistics system:

1. High-Precision Rolled Aluminum Profiles

• Curvature Radius Range: R150–R3000 mm

• Curvature Consistency Error: < 0.3°

• Flatness: < 0.5 mm

• Joint Gap: < 0.1 mm

2. Customized Asymmetric Cross-Section Profiles

• Made from high-strength 6063-T5 aluminum alloy (tensile strength ≥ 200 MPa)

• Cross-section tolerance: ±0.5 mm or tighter

• Unit weight up to 44.25 kg/m, supporting heavy-duty applications

3. Cleanroom-Grade Surface Treatment

• Mirror-molded surfaces with Ra ≤ 0.03–0.05 μm to eliminate extrusion marks

• Hard anodizing (hardness 400–500 HV) for enhanced wear resistance

• Fully protected during production and packaging to meet Class 100 cleanroom standards
