Core Product Offerings
Nanpi Haokai specializes in three main product categories, each designed to meet specific industrial requirements:
1. Precision Metal Stamping Parts
The company’s metal stamping capabilities cover a wide range of applications, with particular expertise in producing complex components with tight tolerances. Their flagship product, the metal shovel, exemplifies their stamping excellence:
- Manufactured from single metal sheets through integrated stretching and bending
- No splicing or welding ensures superior strength and durability
- Features reinforced ribs and smooth, rounded edges for optimal performance
- Standard mounting holes for easy assembly without secondary processing
- Available in various materials including cold-rolled steel, stainless steel, aluminum alloy, and copper
This approach to stamping reduces clients’ production costs by eliminating the need for additional processing steps while ensuring component reliability in demanding environments.
2. CNC Machined Components
Nanpi Haokai’s CNC machining services provide precise components for applications requiring exacting standards. Their brass connecting rods demonstrate the company’s CNC capabilities:
- One-piece molded construction for dimensional accuracy
- Smooth surface finish with no burrs for seamless insertion and removal
- Made from high-quality brass with excellent conductivity and corrosion resistance
- Alternative material options include phosphor copper, red copper, aluminum, and iron
- Customizable dimensions, structures, and surface treatments (tin plating, zinc plating, polishing)
These components serve critical functions in connectors, automotive parts, new energy equipment, medical instruments, and electrical terminals, where reliable electrical connections are essential.
3. Non-Standard Custom Metal Parts
Understanding that many industrial applications require unique solutions, Nanpi Haokai excels at producing non-standard custom metal components. Their precision knurled galvanized sleeves (metal bushings) showcase this capability:

This rigorous approach ensures that every component leaving the factory meets or exceeds customer expectations, building trust and long-term relationships with clients worldwide.
FAQ
What materials can Nanpi Haokai use for custom metal stamping parts?
We work with a wide range of materials including various steels (cold-rolled, stainless, spring), non-ferrous metals (aluminum, copper, brass), and specialized alloys. Our material selection depends on your specific application requirements for strength, corrosion resistance, conductivity, and other properties.
How does the company ensure dimensional accuracy in CNC machined components?
We use advanced CNC machining centers with high-precision servo systems and ball screws. Our process includes rigorous quality control with coordinate measuring machines (CMM) for critical dimensions. We also implement statistical process control (SPC) to maintain consistent quality across production batches.
What is the minimum order quantity for custom metal parts?
We accommodate both small prototype batches and large-volume production. Our minimum order quantity depends on the complexity of the part and required setup. For simple components, we can produce as few as 100 pieces, while more complex parts might have higher MOQs due to tooling costs.
How long does it typically take to produce custom metal components?
Lead times vary based on part complexity and order quantity. Simple stamped parts might take 2-3 weeks from design approval to shipment, while complex CNC machined components could require 4-6 weeks. We work closely with customers to optimize production schedules and meet project deadlines.
Can Nanpi Haokai assist with product design and development?
Absolutely. Our experienced engineering team provides design for manufacturing (DFM) services to optimize your components for cost-effective production. We can review your drawings or concepts and suggest modifications to improve manufacturability without compromising functionality.
