Technical Inspection & Quality Control

Our manufacturing facilities strictly comply with ISO/TS 16949 automotive production guidelines. Quality control is integrated into every stage to ensure consistent performance for every air suspension trailing arm XJL-110:

• Dimensional Accuracy Checks: Comprehensive gauge testing for 575mm center-to-center pitch, 62x70mm cross-section, bushing inner diameter, and overall length.

• Load & Bending Resistance Testing: Verified on hydraulic press testing machinery to ensure compliance with design load-deflection and structural yield standards.

• Metallographic & Hardness Testing: Metallurgical analysis confirms optimal heat treatment grain structure and uniform surface hardness across all components.

Manufacturing Process

Our facility operates advanced commercial vehicle suspension production lines matching ISO/TS 16949 quality norms:

1. Material Testing: Certified alloy spring steel raw materials undergo strict chemical composition and tensile strength checks.

2. Precision Forging & CNC Punching: High-precision forging and CNC punching ensure exact hole positioning, smooth contours, and clean edges.

3. Heat Treatment & Shot Peening: Computerized thermal quenching and tempering maximize material toughness, followed by shot peening for long fatigue life.

4. E-Coating & Assembly: Corrosion-resistant electrophoretic coating (E-coating) is applied before fitting high-durability rubber or poly bushings and protective wear clips.

5. Final QC & Packaging: 100% visual, dimensional, and load test inspection prior to export packing.

Packaging & Export Shipping

To ensure your air suspension trailing arm XJL-110 shipment arrives in perfect condition during ocean transit, we enforce strict export packaging standards:

• Anti-Rust Protection: Treated with rust-inhibiting coatings and wrapped in durable waterproof plastic wrap film.

• Non-Fumigation Export Pallets: Securely bundled on heavy-duty non-fumigation plywood pallets with protective wooden blocks and corner guards, ensuring seamless international customs clearance without fumigation delays.

• High-Tensile Steel Strapping: Bound tightly with heavy steel bands to prevent displacement during ocean freight.

• Container Optimization: Custom container loading plans maximize weight efficiency in 20ft and 40ft containers.
