Custom Spring Component Manufacturing Capabilities
At Nanpi Haokai, we specialize in producing three main categories of spring components that serve diverse industrial applications:
1. Precision Stamped Spring Components
Our metal shovel is a prime example of our stamping capabilities. Manufactured from single-piece sheet metal through integrated stretching and bending processes, this component features no splices or welds, ensuring exceptional durability. The reinforced ribs and smooth arc surface enable efficient material handling while the standard mounting holes simplify assembly. Available in cold-rolled steel, stainless steel, aluminum alloy, and copper materials, this component adapts to various industrial equipment requirements.
Another key product in this category is our brass stretched copper shell (connector terminal housing). Produced through precision stamping and drawing, this seamless component offers compact structure and precise positioning. Made from high-quality copper materials, it provides stable conductivity and excellent corrosion resistance. The product supports customization in multiple materials, dimensions, and premium surface treatments like gold, silver, or nickel plating, making it ideal for aviation plugs, new energy connectors, and sensor applications.
2. CNC Machined Spring Components
Our brass connecting rods exemplify our CNC machining expertise. Manufactured as single-piece components with precise dimensions and smooth surfaces, these rods ensure seamless insertion and extraction without jamming. Made from high-quality brass with excellent conductivity and heat dissipation, they resist oxidation and corrosion effectively. The product supports material substitution with phosphor copper, red copper, aluminum, or iron, along with customizable dimensions, structures, and surface treatments like tin or zinc plating and polishing. Primary applications include connectors, automotive parts, new energy equipment, medical instruments, and electrical terminals.
The precision knurled galvanized sleeve (metal bushing) represents our non-standard custom hardware capabilities. Produced through CNC integrated turning, this component features smooth tube walls and precise dimensions. The middle knurling design significantly enhances assembly friction to prevent slippage during equipment operation. After galvanizing treatment, it offers excellent corrosion resistance and long service life. The product supports processing in multiple materials including iron, stainless steel, brass, and aluminum, with customizable tube diameters, lengths, and wall thicknesses for applications in fasteners, wire harness connectors, instrument bushings, furniture hardware, and mechanical positioning.
3. Injection Molded Spring Components
While our core expertise lies in metal components, our injection molding capabilities allow us to produce plastic spring elements that complement our metal offerings. This integrated approach enables us to provide complete solutions where metal and plastic components need to work together seamlessly.
Our standard elastic clips demonstrate our ability to mass-produce general-purpose hardware components. Manufactured through integrated stamping and bending with quenching treatment, these clips balance hardness and elasticity for stable clamping force. Available in complete specifications with ample stock, they support multi-material customization and anti-rust surface treatments. Customizable dimensions and arcs make them suitable for fixing and clamping electrical appliances, pipes, precision instruments, and industrial equipment across various assembly scenarios.
| Product Feature | Technical Specification | Customization Options |
|---|---|---|
| Material | Cold-rolled steel, stainless steel, brass, aluminum, etc. | Material substitution per customer requirements |
| Tolerance | ±0.05mm for precision components | Tighter tolerances available upon request |
| Surface Treatment | Galvanizing, polishing, plating, etc. | Custom surface treatments per application needs |
| Production Capacity | 30+ press machines, 30+ CNC machines | Scalable for projects of any size |
