Inner Sleeve for Automotive Suspension

As a leading automotive suspension sleeve manufacturer, we specialize in producing cold forged inner sleeves that play a vital role in modern suspension systems. The inner sleeve absorbs road shocks and vibrations, reduces noise and harshness, and ensures a smoother and more stable driving experience.

Precision Cold Forming Technology

Our advanced multi-station cold forming process enables us to mold near-finished sleeves without additional machining. This results in:

• High dimensional accuracy and tight tolerances for safety-critical suspension parts

• Consistent quality across large production volumes

• Cost-effective production by reducing secondary machining steps

Key Features of Inner Sleeves

• Shock & Vibration Absorption – Improves ride comfort and reduces NVH (Noise, Vibration, Harshness)

• High Strength & Durability – Made from alloy steel (20Cr, 40Cr, or customized materials) with excellent fatigue resistance

• Corrosion Protection – Various finishes available, including manganese phosphating, chrome plating, and custom coatings

• Custom Engineering – Tailored solutions based on drawings or specific technical requirements

Applications

Our precision inner sleeves are widely used in:

• Passenger car suspension systems

• Commercial trucks and heavy-duty vehicles

• Electric and new energy vehicles where lightweight and durability are critical

Why Choose Us

• Automotive-Grade Quality – Zero-defect target with strict inspection at every stage of production

• Flexible Manufacturing – From standard sizes to custom suspension sleeves and special bushings

• Proven Expertise – Over 20 years of experience in cold forging and precision machining
