Symbol Stahlmaterial

High-Strength Steel:

Designed for maximum durability and load capacity, making them widely used in OEM suspension systems where safety and long service life are critical.

  • 40Cr: After quenching and tempering, 40Cr offers excellent toughness and wear resistance for structural suspension parts.
  • 4140: With 650–850 MPa yield strength after heat treatment, 4140 delivers outstanding fatigue resistance and load-bearing for heavy-duty suspension components.
Symbol Stahlmaterial

Aerospace Aluminum Alloy:

Optimize weight reduction, offering the best strength-to-weight ratio while maintaining reliable strength, the best choice for aftermarket tuning and performance upgrading.

  • Aluminium 6061: Over 40% weight reduction with no strength compromise compared to original parts.
  • Aluminium 7075: Up to 503 MPa yield strength, almost twice that of 6061, the best material for racing suspension.

Surface Finishing & Heat Treatment

Although most suspension parts we produce are forged or cast blanks, we still have the capability to offer comprehensive post-process options through our in-house facility and supply chain to get your products perfect for sale. Which including:

🔷 Kugel-/Sandstrahlen🔷 Solution Heat Treatment + Aging
🔷 Anodisieren (Typ II/III)🔷 Härten und Anlassen
🔷 Überzug🔷 Glühen
🔷 Pulverbeschichtung🔷 Normalisierung

Precision Throughout the Process

Tolerance control is not the final check in HDC Manufacturing; we are aware that the tolerance of suspension components not only affects the safety but also the driving experience, so we implement strict processes to offer you the best products.

🔷 Deform Analysis: Advanced software simulates forging metal flow to prevent internal defects.
🔷 Tooling Manufacturing: Expert engineers optimize die structures for consistent, high-precision manufacturing.
🔷 In Process Inspection: Real-time checks and measurements strictly maintain required tolerances.
🔷 CNC-Finishing: Multi-axis machining achieves ±0.01mm tolerances for perfect fitment and geometry.
