Product Range and Customization Capabilities
Nanpi Haokai Hardware’s product portfolio includes precision stamping parts, high-precision instrument turning parts, and injection-molded parts. Among these, the stamping spring pieces are a standout offering, known for their durability, precision, and customizability. The company’s metal shovel, a flagship stamping product, is crafted from a single piece of material through a stretching and bending process, eliminating the need for splicing or welding. This results in a robust and durable product that is resistant to bending and cracking, featuring reinforced ribs, a smooth arc shovel surface, and standard mounting holes for easy assembly and use.

Another key product is the brass connecting rod, a CNC-machined component that is integrally formed for precise dimensions and a smooth surface free of burrs. Made from high-quality brass, this product offers excellent conductivity and thermal conductivity, along with resistance to oxidation and corrosion. It supports various material substitutions, including phosphor copper, red copper, aluminum, and iron, and can be customized in terms of size, structure, shape, and surface treatments such as tin plating, zinc plating, and polishing. This versatility makes it ideal for use in connectors, automotive parts, new energy equipment, medical instruments, and electrical terminals.
Precision Knurled Galvanized Sleeve (Metal Bushing)
The precision knurled galvanized sleeve is another non-standard custom hardware piece offered by Nanpi Haokai Hardware. Manufactured through CNC integrated turning, this product features a smooth tube wall, precise dimensions, and a knurled design in the middle to enhance assembly friction and prevent slippage during equipment use. The galvanized finish provides excellent corrosion resistance and extends the product’s service life. It supports processing in multiple materials, including iron, stainless steel, brass, and aluminum, and can be customized in terms of tube diameter, length, and wall thickness, making it suitable for a wide range of applications such as fasteners, wire harness connectors, instrument bushings, furniture hardware, and mechanical positioning.
