The core advantages of the Aluminum alloy housing assembly
Material performance advantages
Lightweight (reducing weight by over 60% compared to steel parts), excellent thermal conductivity (improving equipment heat dissipation efficiency), tensile strength ≥ 220 MPa, hardness ≥ 80 HB. After passivation treatment, salt spray test can last up to 48 hours. Aluminum alloy can be 100% recycled, meeting green production standards.
Precision die-casting process advantages
Cold chamber high-pressure die-casting realizes integrated molding of complex structures, reducing processes by 50%; dimensional tolerance controlled at IT10 - IT12 level, deviation of key parts ≤ ±0.03mm; single mold cycle 15 - 30 seconds, yield stable at over 98%, suitable for large-scale mass production.
Functional structure design advantages
Integrated installation holes, ventilation holes, positioning holes and other multi-specification functional holes are provided, with mortise and tenon joint slots reserved, with gap ≤ 0.05mm; internal reinforcing ribs are set, improving deformation resistance by 40%, and can be adapted to equipment assembly without secondary processing.
