Mounting eye of Shock Absorber Parts-Car Suspension Parts-Auto Modifications-Aftermarket Parts

Core Advantages: 1)Extreme Precision Control: Utilizes 5-axis simultaneous CNC machining, with dimensional tolerance controlled within ±0.01mm, ensuring seamless fit with the original car chassis and eliminating abnormal noise and looseness. 2)Material Mechanics Optimization: Uses 6061-T6/7075-T6 aerospace aluminum alloy/4140 alloy steel. After anodized/hard anodized, heat treatment (aging/quenching), the tensile strength is increased by 30%, maintaining structural rigidity even in continuous bumps and extreme steering scenarios. 3)Balance of Lightweight and Durability: Through topological optimization design (material reduction + stability enhancement structure), it is 15% lighter than the original parts, and the fatigue life reaches 500,000 cycles (far exceeding the industry standard of 300,000 cycles). Technical Specifications Processing Technology: Rough milling → Fine milling → CNC turning → Surface anodizing (for aluminum parts)/chrome plating or electroplating (for steel parts) to improve corrosion and wear resistance. Inspection System: Full-size inspection with Coordinate Measuring Machine (CMM) + Dynamic load simulation test (simulating 100,000 km road conditions).
