QL factory makes the world-class quality die casting parts for customers. 

1>. Superior Materials and Advanced Manufacturing

- High-Performance Alloys: Crafted from premium-grade materials such as ADC12 aluminum alloy, AZ91D magnesium alloy, or custom-engineered metal formulations, ensuring exceptional strength-to-weight ratios, corrosion resistance, and thermal stability.  

- Precision Die-Casting Process: Utilizes high-tolerance molds (±0.02mm) and state-of-the-art die-casting machines (e.g., LK Group, Bühler series) to achieve intricate geometries, ultra-thin walls, and near-net-shape production, minimizing secondary machining.  

2>.Microstructural Integrity and Surface Excellence

- Defect-Free Internal Structure: Vacuum die-casting and ultra-low-speed injection technologies eliminate porosity and shrinkage, delivering uniform grain structures and mechanical properties (e.g., tensile strength, elongation) exceeding ASTM, DIN, and ISO standards.  

- Premium Surface Finish: Mirror-polished mold surfaces (Ra ≤0.4μm) or advanced coatings (e.g., DLC diamond-like carbon) enable components to meet aesthetic requirements for plating, painting, or high-end decorative finishes without post-processing.  

3>. Micron-Level Tolerance Control

- Ultra-Tight Precision: Critical dimensions are consistently maintained within ±0.05mm, with mating surfaces achieving IT7-IT8 grade accuracy, ideal for demanding applications like automotive powertrains and precision electronics.  

- Batch-to-Batch Consistency: Full digital process control (MES + SPC systems) ensures minimal dimensional and
