Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer established in 1998, specializing in precision stamped metal components. Our Special-shaped Stamped Steel Parts for Automotive Suspension Systems are engineered to meet the demanding requirements of heavy-duty vehicles and off-road equipment. With over two decades of experience and annual export sales exceeding US$5 million, we deliver parts that combine exceptional fatigue resistance with complex geometries, ensuring long service life under cyclic loading.
Below we provide a detailed overview of our product features, technical specifications, and the benefits you can expect when partnering with Boli Hardware.
Product Features & Advantages
- Custom Special-Shaped Design: Our parts are manufactured to your exact blueprints, accommodating complex contours, holes, bends, and brackets for suspension control arms, stabilizer bar links, steering knuckles, and other critical components.
- Heavy-Duty Material Selection: We use high-strength steel grades (e.g., Q235, 45#, or equivalent) to withstand extreme loads and impact forces in off-road, truck, and agricultural suspension systems.
- Fatigue Resistance: Each part undergoes rigorous stress analysis and optional fatigue testing to ensure consistent performance over millions of cycles – ideal for long-life suspension applications.
- Precision Stamping Process: Advanced progressive dies and press machines (up to 630 tons) guarantee tight tolerances (±0.1mm – ±0.3mm) and repeatable quality across large production runs.
- Surface Treatment Options: Choose from zinc plating, phosphating, powder coating, or e-coating to enhance corrosion protection and wear resistance.
- Cost-Effective Production: As a direct manufacturer, we offer competitive pricing without compromising quality, with MOQ as low as 500 pieces for initial orders.

Frequently Asked Questions
-
Can you produce parts with complex cutouts or bends?
Yes, our progressive dies and transfer presses can handle intricate shapes, including multiple bends, holes, slots, and countersinks. We will evaluate your drawing and advise on the best stamping approach. -
What is the minimum order quantity (MOQ) for custom stamped parts?
Our standard MOQ is 500 pieces for a new tooling setup. However, we can accommodate smaller trial orders (e.g., 100–200 pieces) for prototype validation at a higher unit cost. -
How do you ensure the fatigue resistance of heavy-duty suspension parts?
We select high-strength materials and may apply stress-relief heat treatment. Additionally, we offer optional fatigue testing (e.g., sine wave, block cycle) to validate performance under simulated service loads. -
What surface treatments are available for corrosion protection?
We offer zinc plating (clear, yellow, black), phosphating, powder coating (various colors), and e-coating. The most suitable option depends on the operating environment (e.g., road salt, moisture). -
Do you provide tooling design and fabrication?
Yes, we have an in-house tooling department that designs and builds progressive dies, transfer dies, and simple forming dies. Tooling ownership belongs to the customer after payment. -
What is your typical lead time for a new product?
Sample lead time: 15–20 working days after tooling completion. First mass production: 30–45 working days after sample approval. Urgent orders can be expedited with a surcharge. -
Do you export to Europe and North America?
Absolutely. Our main markets include North America, Eastern/Western Europe, Southeast Asia, and Oceania. We ship via sea or air from Tianjin, Qingdao, Shanghai, or Foshan ports. -
Can you provide certificates of material or dimensional reports?
Yes, we can issue material test reports (MTR) from the steel mill, as well as inspection reports for dimensions and surface finish. Additional certifications (e.g., IATF 16949) are available upon request; please confirm your requirements.
