Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998, specializing in precision metal stampings. Our Precision Ground Irregularly Shaped Steel Stampings are crafted from premium 304 stainless steel, with thickness ranging from 0.8mm to 4mm and an exceptional accuracy of 0.02mm. With over two decades of experience and an annual export value of US$5-10 million, we deliver components that meet the rigorous demands of global industries including automotive, electronics, and heavy machinery. Each stamping is ground to perfection, ensuring burr-free edges and consistent tolerances that reduce assembly time and improve product reliability.
Our irregularly shaped stampings are designed for complex geometries where standard blanks fall short. Whether you need intricate brackets, custom clips, or specialized mounting plates, our advanced stamping and grinding capabilities guarantee a precise fit every time. The combination of 304 stainless steel's corrosion resistance and our 0.02mm accuracy makes these parts ideal for environments where durability and tight tolerances are non-negotiable.
Product Features & Technical Specifications
- Material Excellence: 304 stainless steel offers excellent rust resistance, high strength, and good formability – perfect for outdoor, marine, or chemical exposure.
- Precision Ground Surface: Each stamping undergoes a secondary grinding process to achieve a smooth, flat surface with tight parallelism, reducing friction and wear in assembled systems.
- Custom Irregular Shapes: We can produce virtually any profile – from asymmetrical brackets to contoured plates – with repeatable precision across large production runs.
- Thickness Versatility: Available in 0.8mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, and 4.0mm thicknesses, with intermediate sizes also possible.
- 0.02mm Dimensional Accuracy: Our CNC-controlled stamping presses and skilled operators ensure that every part meets the specified tolerance, enabling seamless integration into your assemblies.
- Burr-Free Edges: In-house deburring and grinding eliminate sharp edges, enhancing safety and preventing damage to mating components.
- Scalable Production: From prototype quantities to high-volume orders (50,000+ pieces per month), we maintain consistent quality and fast lead times.

Our stampings are manufactured using progressive dies and precision grinding machines that ensure repeatability across thousands of parts. The 0.02mm accuracy is verified through CMM (Coordinate Measuring Machine) inspections, and we provide detailed inspection reports upon request. This level of precision reduces your need for secondary machining, saving you time and cost.

Frequently Asked Questions
-
Q: What is the minimum order quantity (MOQ) for these custom stampings?
A: We typically require an MOQ of 500 pieces for standard irregular shapes, but lower quantities are available for prototypes. Please contact us for specific requirements. -
Q: Can you achieve a tolerance tighter than 0.02mm?
A: Yes, we can achieve ±0.01mm on certain features, but this may affect lead time and cost. Please provide your drawing for a feasibility evaluation. -
Q: Do you offer surface finishing options beyond grinding?
A: Yes, we can also provide passivation, electropolishing, or powder coating. These are available upon request. -
Q: How do you ensure the 304 stainless steel material is genuine?
A: We source material from certified mills and perform chemical composition analysis. A material test certificate can be provided with each shipment. -
Q: What file formats do you accept for custom designs?
A: We accept STEP, IGES, DXF, and PDF drawings. For complex shapes, a 3D CAD file is preferred. -
Q: What is the typical lead time for a production order?
A: For orders up to 10,000 pieces, lead time is typically 2-3 weeks after tooling approval. Larger orders may require 4-5 weeks. -
Q: Can you handle parts that require both stamping and welding?
A: Yes, we have in-house welding capabilities for assembly of sub-components. Please specify your requirements. -
Q: Do you offer free samples for evaluation?
A: We provide free samples for standard shapes. For custom designs, a sample fee may apply, which is refundable with your first order.
