Core Product Offerings
Nanpi Haokai’s product portfolio focuses on three main series of customizable components:
1. Precision Stamping Parts
The company’s metal shovel is a prime example of its stamping expertise. Manufactured through one-piece stretching and bending from whole plates, this product features no splices or welds, ensuring exceptional durability and resistance to bending or cracking. The integrated design includes reinforcing ribs, smooth arc-shaped shovel surfaces, and standard mounting holes for easy assembly without secondary processing. Customers can choose from materials including cold-rolled steel, stainless steel, aluminum alloy, and copper to suit various equipment applications.

2. CNC Machined Components
The brass connecting rod demonstrates Nanpi Haokai’s precision CNC capabilities. Manufactured as a single piece with precise dimensions and smooth surfaces, this component offers excellent conductivity and thermal properties while being resistant to oxidation and corrosion. The company can produce these rods in various materials including phosphor copper, red copper, aluminum, and iron, with customizable dimensions, structures, and surface treatments like tin plating, zinc plating, or polishing. These components find applications in connectors, automotive parts, new energy equipment, medical instruments, and electrical terminals.
3. Custom Injection Molded Parts
Nanpi Haokai also specializes in non-standard custom injection molding, supporting clients from product design optimization through prototyping and mass production. The company’s precision knurled zinc-plated sleeves (metal bushings) exemplify this capability. Machined through CNC turning, these sleeves feature smooth walls, precise dimensions, and knurled middle sections for enhanced friction during assembly. The zinc plating provides excellent corrosion resistance, while the company can produce these parts in various materials with customizable tube diameters, lengths, and wall thicknesses for applications including fasteners, wire harness connectors, instrument bushings, furniture hardware, and mechanical positioning.
