Result: Completed batch within 2 weeks, enabling critical experiments.
From raw material screening (spectral/X-ray tested) to AI-monitored precision extrusion (±0.05mm) and 360° batch certification, our quality control integrates cutting-edge tech and global standards (ISO/IATF/AS9100). We enforce zero-tolerance checks on strength, corrosion resistance, and surface integrity, ensuring aerospace-grade aluminum solutions that are fully traceable and defect-free for mission-critical industries.
All raw materials undergo spectral/X-ray analysis and vacuum casting verification to ensure compliance with ASTM/GB standards, eliminating impurities and guaranteeing aerospace-grade alloy integrity (6061/7075).
Real-time AI systems track extrusion pressure (±1%), temperature (±2°C), and dimensional tolerances (±0.05mm), with automated alerts for deviations, ensuring military-grade precision across 19 production lines.
Every batch undergoes 360° testing—fatigue resistance (200-700 MPa), corrosion simulation (1000+ salt spray hours), and surface integrity checks—backed by ISO/IATF/AS9100 certifications for 100% traceable, defect-free delivery.
Company in Chinese means exuberant and vigorous. With continuous progress and development in past two decades, now Company machine is becoming the leading machine manufacturer and solution supplier in HVAC and Refrigeration industry.
