Welcome to Anping County Boli Hardware Wiremesh Products Factory – your reliable partner for high-quality metal stamping solutions. Since 1998, we have specialized in producing Special-shaped Stamped Steel Parts made from premium 65Mn Spring Steel, with a guaranteed hardness of 60-65 HRC and durable zinc plating for corrosion resistance. Our parts are designed to meet the rigorous demands of automotive, industrial, and machinery applications, ensuring long service life and consistent performance. With over two decades of experience and annual exports exceeding US$5 million, we deliver precision and reliability to global markets.
Product Features & Technical Specifications
- Material Excellence: 65Mn spring steel offers high fatigue strength, excellent elasticity, and wear resistance, making it ideal for components that undergo repeated stress.
- Controlled Hardness: Each part is heat-treated to achieve 60-65 HRC, providing the perfect balance of toughness and hardness for demanding environments.
- Corrosion Protection: A uniform zinc plating layer (thickness 8-12 μm) effectively shields against rust and oxidation, extending product lifespan in harsh conditions.
- Custom Shapes: We specialize in special-shaped stampings – from complex brackets and clips to custom spring washers and retainers – produced to your exact blueprints.
- Precision Stamping: Advanced progressive dies and CNC-controlled presses ensure tight tolerances (typically ±0.1 mm) and repeatable quality across large volumes.
- Versatile Applications: Suitable for automotive suspension systems, industrial machinery, agricultural equipment, electrical enclosures, and more.

Frequently Asked Questions (FAQ)
1. What is the minimum order quantity (MOQ) for special-shaped stamped parts?
Our MOQ typically starts at 1,000 pieces for standard designs, but we can accommodate smaller quantities for prototyping with a slightly higher unit cost. Please inquire about your specific needs.
2. Can you provide samples before mass production?
Yes, we offer samples upon request. A sample fee may apply for custom tooling, which is refundable for bulk orders. Lead time for samples is usually 7–15 working days.
3. How do you ensure the hardness of 60-65 HRC is consistent?
We use a Rockwell hardness tester for every batch and maintain strict heat treatment parameters. A certificate of analysis can be provided with each shipment.
4. What is the typical lead time for production?
After tooling approval, production lead time is 15–30 working days, depending on order quantity and complexity. We also offer expedited service for urgent orders.
5. Is the zinc plating RoHS compliant?
Yes, our zinc plating process uses trivalent passivation, which is RoHS compliant and environmentally friendly. We can also provide other finishes like black oxide or Dacromet on request.
6. Can you handle complex shapes with tight tolerances?
Absolutely. Our advanced stamping presses and precision tooling allow us to achieve tolerances as tight as ±0.05 mm on critical features. We regularly produce parts with multiple bends, offsets, and holes.
7. What file formats do you accept for design drawings?
We accept DXF, DWG, STEP, IGES, and PDF. Our engineers can also work from physical samples to create reverse-engineered drawings.
8. Do you offer any warranty on your products?
Yes, we provide a 12-month warranty against manufacturing defects under normal use conditions. Any dimensional or hardness issues will be addressed promptly.
