To ensure long-term reliability and fatigue resistance, we employ state-of-the-art heat treatment and finishing processes:
Heat Treatment Options:
- Vacuum Heat Treatment: For superior structural integrity.
- Oil & High-Frequency Quenching: Enhancing surface hardness while maintaining core toughness.
- Carburization & Mesh Belt Furnace: Tailored for high-volume industrial consistency.
Surface Protection (Salt Spray Resistance):
- Plating: Zinc, Nickel, Phosphating, and Passivation.
- Specialized Coatings: Anodized treatment, Black coating, and high-durability finishes.
Stable damping performance is critical for vehicle comfort, suspension stability, and long-term operational safety.
Our engineering team focuses on optimizing internal component precision, sealing stability, and oil flow consistency to ensure reliable compression and rebound damping performance under different load conditions.
Engineering Focus:
- Compression and rebound stability
- Oil flow consistency
- High-frequency vibration absorption
- Reduced noise and vibration (NVH)
- Suspension response stability
- Long-term fatigue resistance
Benefits:
- Improved ride comfort
- Better vehicle handling stability
- Reduced suspension wear
- Enhanced driving control
- More reliable long-term operation
