Why Choose Aluminum for Data Base Shell Covers?
Aluminum is widely recognized as an ideal material for telecom and electronic enclosures due to its unique combination of properties:
High Strength-to-Weight Ratio: Provides structural integrity while reducing equipment weight by up to 30% compared to steel.
Excellent Thermal Management: Aluminum alloys typically offer thermal conductivity of around 150-200 W/m·K, crucial for dissipating heat generated by telecom electronics.
Superior Corrosion Resistance: Ensures long-term durability in outdoor and indoor environments, compliant with IEC 60068-2 corrosion resistance standards.
Outstanding EMI/RFI Shielding: Aluminum shields sensitive electronics from electromagnetic and radio-frequency interference.
Huawei chose Aluminum A380 alloy for its excellent castability, mechanical strength (tensile strength up to 324 MPa), and superior thermal conductivity (around 160 W/m·K).
Die Casting Process and Solutions Implemented
Neway provided Huawei with an integrated, optimized die casting solution, leveraging advanced manufacturing capabilities, including:
Precision Tooling Development
Neway employed state-of-the-art CAD/CAM software (Siemens NX) and mold-flow simulations (Moldex3D) to engineer precision tooling from high-performance H13 tool steel. Dies were heat-treated to 48 HRC, ensuring exceptional longevity (exceeding 120,000 cycles) and consistent dimensional precision within ±0.01 mm.
High-Pressure Die Casting Production
Advanced high-pressure die casting machines, operating at pressures of 90-160 MPa, consistently produced defect-free aluminum shell covers. Precise temperature control (680-710°C) and optimal injection speed parameters minimized internal porosity (<0.05%) and surface defects (below 0.3% incidence rate).
Comprehensive Post-Casting Processing
Neway implemented extensive post-casting finishing operations to meet Huawei’s exact specifications:
CNC Precision Machining: Utilizing advanced CNC machining processes to achieve final dimensional accuracy of ±0.02 mm, meeting the tightest telecom industry tolerances.
Surface Treatment: Premium-grade anodizing achieved cosmetic-level surface finishes, meeting Ra ≤1.2 µm as specified by Huawei.
Quality Inspection: Employing rigorous quality controls, including Coordinate Measuring Machines (CMM) for dimensional checks (±0.005 mm accuracy) and X-ray inspection (ASTM E505) to ensure porosity-free castings.
