Core Product Range
Nanpi Haokai specializes in three main product categories, each designed to address specific industrial needs:
1. Precision Stamping Spring Clips
The company’s flagship product features one-piece construction from solid material through stretching and bending processes. This design eliminates welds and joints, creating components that are exceptionally strong and resistant to bending or cracking. Key features include:
- Reinforced ribs for added strength
- Smooth, rounded shovel surfaces
- Standard mounting holes for easy assembly
- Material options including cold-rolled steel, stainless steel, aluminum alloy, and copper
These clips are ideal for various industrial applications, including equipment mounting, component fixation, and assembly line operations. Their design reduces the need for secondary processing, saving customers time and money in production.
2. CNC Machined Brass Connecting Rods
Manufactured through precision CNC turning, these connecting rods feature:
- One-piece construction with precise dimensions
- Smooth surfaces free from burrs
- Excellent electrical and thermal conductivity (when made from brass)
- Corrosion resistance and oxidation protection
Customizable in various materials including phosphor copper, red copper, aluminum, and iron, these rods support multiple surface treatments like tin plating, zinc plating, and polishing. They serve as critical components in connectors, automotive parts, new energy equipment, medical instruments, and electrical terminals.
3. Precision Knurled Galvanized Sleeves
These specialized components, produced through CNC turning, offer:
- Smooth inner walls with precise dimensions
- Knurled exterior for enhanced friction during assembly
- Galvanized surface for corrosion resistance
- Customizable material options and surface treatments
Widely used in fasteners, wire harness connectors, instrument bushings, furniture hardware, and mechanical positioning, these sleeves demonstrate the company’s ability to create non-standard components that solve specific engineering challenges.
