Core Product Offerings
As a specialized manufacturer, we focus on three primary product categories that form the backbone of our business:
1. Precision CNC Turning Parts
Our CNC turning capabilities produce components with tolerances as tight as ±0.01mm, suitable for demanding applications in automotive, aerospace, and medical industries. The brass electrode components we manufacture exemplify this precision, featuring smooth surfaces free from burrs and consistent dimensional accuracy. These electrodes are widely used in EDM (Electrical Discharge Machining) processes where material purity and dimensional stability are critical.
2. Custom Metal Stamping Components
Our precision stamping division produces millions of components annually for global clients. The metal shovel, one of our flagship stamped products, demonstrates our ability to create complex shapes from single metal sheets without welding or assembly. This design approach ensures maximum strength and durability while minimizing production costs for our customers.
The yellow copper connecting rod represents our CNC machining expertise. Machined from solid brass billets, these components feature precise dimensions and excellent electrical conductivity. Their smooth surfaces ensure reliable performance in connector applications where consistent contact is essential.
3. Specialized Hardware Solutions
We excel at producing non-standard components that solve specific customer challenges. The precision knurled galvanized sleeve (metal bushing) showcases this capability. Manufactured through CNC turning and featuring a knurled middle section, this component provides enhanced friction for secure assembly in various applications. The zinc plating offers excellent corrosion resistance, extending the product’s service life in harsh environments.
Our yellow copper stretched copper shell (connector terminal housing) demonstrates our precision stamping capabilities. This seamless component provides reliable electrical connections with its stable conductivity and corrosion resistance. The ability to customize materials, dimensions, and surface treatments makes this product ideal for diverse connector applications.
Material and Process Expertise
Understanding material properties is fundamental to our manufacturing process. We work with a wide range of metals including cold-rolled steel, stainless steel, aluminum alloys, copper, and brass. Each material selection considers factors such as mechanical strength, electrical conductivity, corrosion resistance, and cost-effectiveness.
Our surface treatment capabilities enhance both functionality and aesthetics. Standard options include zinc plating for corrosion protection, tin and nickel plating for improved solderability, and polishing for enhanced appearance. For premium applications, we offer gold and silver plating that provide excellent conductivity and corrosion resistance while meeting strict aesthetic requirements.
| Material Type | Key Properties | Typical Applications |
|---|---|---|
| Cold-rolled Steel | High strength, cost-effective | Structural components, brackets |
| Stainless Steel | Corrosion resistant, durable | Medical instruments, food processing |
| Brass/Copper | Excellent conductivity, corrosion resistant | Electrical connectors, terminals |
| Aluminum Alloys | Lightweight, good strength-to-weight ratio | Aerospace, automotive components |
Quality Assurance System
Our ISO 9001:2015 certified quality management system ensures consistent product quality through every production stage. From initial material inspection to final packaging, we implement strict quality control measures:
- Incoming material inspection using spectrometers and tensile testing machines
- In-process quality checks at each manufacturing stage
- Final inspection including dimensional verification and functional testing
- Comprehensive batch traceability for all components
- Continuous improvement programs based on customer feedback
Customization Capabilities
What sets Nanpi Haokai apart is our ability to transform customer concepts into production-ready components. Our comprehensive customization services include:
- Material selection guidance based on application requirements
- Design optimization for manufacturability and cost efficiency
- Prototype development and testing
- Small batch production for market testing
- Mass production with consistent quality
- Post-production services including assembly and packaging
This end-to-end capability allows us to serve as a true manufacturing partner rather than just a supplier. We work closely with customers during the product development phase to identify potential manufacturing challenges and propose cost-effective solutions without compromising quality.
Industry Applications
Our components find applications across diverse industries thanks to their quality and versatility:
- Automotive: Precision bushings, connectors, and structural components
- Electronics: EMI shielding components, connectors, and housing

- Energy: Components for solar inverters and wind turbine systems
- Industrial: Custom brackets, fasteners, and mechanical components
FAQ
What types of CNC turning services do you offer?
We provide comprehensive CNC turning services including precision machining of brass, copper, stainless steel, and aluminum components. Our capabilities range from simple cylindrical parts to complex shapes with multiple diameters and features. We specialize in producing components with tight tolerances (±0.01mm) for applications requiring high precision.
How do you ensure the quality of your brass electrode components?
Quality control begins with rigorous material inspection using advanced spectrometers. During production, we implement in-process checks at each machining stage. Final inspection includes dimensional verification using CMM (Coordinate Measuring Machines) and surface finish testing. All components undergo batch testing to ensure consistency before shipment.
What is your minimum order quantity for custom metal stamping?
We accommodate both small and large production volumes. Our minimum order quantity starts at 1,000 pieces for most stamped components, though we can produce smaller quantities for prototype development or market testing. For high-volume orders exceeding 100,000 pieces, we offer additional cost savings through optimized tooling and production processes.
How long does it typically take to produce custom CNC turned parts?
Production timelines depend on component complexity and order quantity. Simple parts can be produced within 5-7 working days after tooling completion, while more complex components may require 10-15 working days. For new projects requiring tooling development, please allow an additional 7-10 days for tooling fabrication and testing.
What surface treatment options are available for your components?
We offer a comprehensive range of surface treatments including zinc plating, nickel plating, tin plating, chrome plating, anodizing, powder coating, and polishing. For premium applications, we provide gold and silver plating services. Each treatment is selected based on the component’s intended application to enhance corrosion resistance, electrical conductivity, or aesthetic appearance.
