Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of precision metal components since 1998. Our Durable Irregularly Shaped Steel Stampings are engineered to meet the toughest demands of global industries, featuring a black oxide finish that enhances corrosion resistance and a tensile strength of 400 MPa for reliable performance under stress. These stampings are produced in strict compliance with international standards, making them a preferred choice for OEMs and distributors worldwide.
Whether you need complex contours, tight tolerances, or high-volume production, our stampings deliver consistent quality. With annual export values exceeding US$5 million and shipping from major ports like Tianjin, Qingdao, Shanghai, and Foshan, we serve markets across North America, Europe, Asia, Africa, and Oceania. Below you will find detailed specifications, advantages, and answers to common questions.
Key Features & Technical Specifications
- Irregular Shapes: Custom dies enable complex geometries – from brackets and clips to custom mounting plates.
- Black Oxide Finish: Provides a matte black appearance, improves wear resistance, and reduces light reflection. Suitable for interior and exterior applications.
- High Tensile Strength (400 MPa): Ensures durability under heavy loads, vibrations, and temperature fluctuations.
- Standard Compliant: Manufactured per industry norms (e.g., ASTM A1008, DIN 1623, or equivalent). Full compliance documentation available upon request.
- Precision Stamping: Tolerances as tight as ±0.1 mm, burr-free edges, and consistent repeatability for high-volume runs.
- Versatile Applications: Used in automotive chassis parts, construction hardware, agricultural machinery, and electronic enclosures.
- Eco-Friendly Process: Black oxide treatment is a chemical conversion coating that does not alter part dimensions and is RoHS compliant.
| Material Options | Carbon steel (SPCC, SPHC), alloy steel, or as specified. |
| Thickness Range | 0.5 mm – 8 mm (customizable) |
| Surface Hardness | Achieved through black oxide: typically 300–400 HV (depending on base material) |
| Corrosion Resistance | Black oxide + oiling provides 24–72 hours salt spray resistance (extendable with supplementary coatings) |
| Operating Temperature | -40°C to 150°C (non‐continuous) |
| Packaging | Export cartons, wooden pallets, or custom packaging per buyer’s request. |

Frequently Asked Questions (FAQ)
-
Can you produce stampings with very complex irregular shapes?
Yes, we specialize in custom dies for irregular geometries. You provide a drawing or sample, and we will create a tool to match your exact shape. Tolerances as tight as ±0.1 mm are achievable. -
What is the black oxide finish and how does it benefit my parts?
Black oxide (Fe₃O₄) is a conversion coating that gives a black appearance, adds mild corrosion resistance, reduces friction, and prevents galling. It does not change part dimensions – ideal for precision components. -
Do you have certificates for material or quality standards?
We can provide material test certificates, dimensional inspection reports, and compliance with standards such as ASTM, DIN, or JIS upon request. Please specify your required standard when inquiring. -
What is the minimum order quantity (MOQ)?
For standard steel stampings, MOQ is typically 500 pieces. For custom shapes with new tooling, MOQ starts at 1000 pieces. Smaller quantities may be possible with a surcharge. -
How long does the black oxide coating last?
Under normal indoor conditions, the coating is stable for years. When exposed to moisture or chemicals, it may require occasional oiling. The base metal’s corrosion resistance is enhanced but not stainless steel level. -
Can you provide samples before bulk production?
Yes, sample stampings can be produced from the production die. There is a sample fee (refundable upon order). Lead time for samples: 10–15 days. -
What packaging options are available for export?
We offer standard cartons, plywood pallets, or custom packaging based on your logistics needs. All packages are designed to prevent damage during ocean freight. -
Do you offer assistance with design for manufacturability?
Absolutely. Our engineering team can review your part design and suggest modifications to reduce cost, improve formability, and maintain strength – all free of charge during the quotation phase.
