2. Key Advantages

Focus on Air Suspension Metal Parts – A Niche Expertise:

With over 40 years of experience in metal parts manufacturing, we specialize in the development and production of metal structural parts for air suspension systems, with deep understanding of the strength, fatigue resistance, and reliability requirements for these critical components.

One-Stop Manufacturing:

• Full in-house production from drawing to finished part

• Complete process chain: precision forming (forging/stamping) → heat treatment → precision machining → (surface finishing)

• Single point of contact, reducing supply chain coordination costs

Process Flexibility:

• For guide arms, thrust rods, and other load-bearing components: precision forging – ensuring unbroken metal flow lines and dense microstructure for high strength and fatigue resistance

• For brackets, mounting bases, and other structural parts: stamping or casting + machining – balancing cost and performance

• Precision machining on critical mounting surfaces and hole positions ensures accuracy

• Optimal process route selected based on customer drawings

Equipment Capabilities:

• Forging equipment, stamping presses, CNC lathes, machining centers, etc.

• In-house heat treatment line

• Surface finishing available upon request (Dacromet, e-coating, powder coating, etc.)

Quality Control:

• Inspection equipment for 100% inspection of critical dimensions

• Mechanical property testing (hardness, tensile strength, etc.) available in-house

• IATF 16949 quality system ensures zero-defect delivery meeting OEM requirements

Certifications & Customer References:

• Certified with IATF 16949, ISO 14001, and hazardous substance control

• Parts supplied via top-tier Tier 1 suppliers to leading domestic and international OEMs

3. Customization & Cooperation

• Supplying to air suspension assembly manufacturers and Tier 1 suppliers (commercial & passenger vehicles)

• Customized manufacturing available upon drawing submission (2D/3D)

• Applicable materials: carbon steel, alloy steel (e.g., 40Cr, 42CrMo, 50CrVA spring steel, etc.)

• Tooling and setup costs quoted separately based on product complexity

• Buyers are encouraged to provide product drawings or technical specifications for feasibility assessment and accurate quotation
