The company’s modern production facilities include more than 30 stamping machines ranging from 30 to 250 tons, along with 30 CNC machines, automatic lathes, CNC sliding head machines, and injection molding machines. This extensive equipment base enables the company to handle all aspects of production from design to after-sales service in an integrated manner.
The company’s production capabilities are further enhanced by its adherence to the ISO9001:2015 quality management system standards. This commitment to quality has enabled Nanpi Haokai to establish strong partnerships with major domestic and international enterprises, earning consistent recognition and praise from clients for its reliable products and excellent service.
Core Product Lines and Customization Services
Nanpi Haokai Hardware specializes in three main product categories: precision stamped parts, CNC machined components, and injection molded parts. The company’s insulated spring assemblies, in particular, have gained significant attention in the market for their exceptional quality and customization options.
The company’s metal shovel, a flagship stamped product, is manufactured through one-piece stretching and bending of whole metal sheets without any splicing or welding. This construction method ensures exceptional durability and resistance to bending or cracking. The product features reinforced ribs, smooth rounded shovel surfaces, and standard mounting holes, enabling smooth material handling and easy assembly without requiring secondary processing by customers. This design effectively reduces production and assembly costs for clients.
Key Product Features and Benefits
The company’s brass connecting rod, a core CNC machined product, is manufactured as a single piece with precise dimensions and a smooth surface free of burrs. Made from high-quality brass, it offers excellent electrical and thermal conductivity while being resistant to oxidation and corrosion. The product supports material substitution options including phosphor copper, red copper, aluminum, and iron, with customizable dimensions, structures, shapes, and surface treatments such as tin plating, zinc plating, and polishing. It finds primary applications in connectors, automotive parts, new energy equipment, medical instruments, and electrical terminals.
Nanpi Haokai’s precision knurled galvanized sleeves (metal bushings) are non-standard customized hardware components produced through CNC turning. These components feature smooth tube walls, precise dimensions, and a knurled middle section that significantly increases assembly friction to prevent slippage during equipment operation. The galvanized anti-rust treatment ensures corrosion resistance and extended service life. The company supports multi-material processing including iron, stainless steel, brass, and aluminum, with customizable tube diameters, lengths, and wall thicknesses. These bushings are widely used in fasteners, wire harness connectors, instrument bushings, furniture hardware, and mechanical positioning applications.
Industry Applications and Customer Solutions
Nanpi Haokai Hardware serves a diverse range of industries including new energy, automotive, electrical appliances, medical equipment, instrumentation, and mechanical manufacturing. The company’s ability to provide customized solutions tailored to specific application requirements has made it a preferred supplier for many global enterprises.
For example, the company’s brass stretched copper shell (connector terminal housing) is a precision stamped and stretched product with seamless one-piece construction, compact structure, and precise positioning. Made from high-quality copper materials, it offers stable electrical conductivity and excellent corrosion resistance. The product supports multi-material substitution, customizable dimensions and structures, and premium surface treatments such as gold, silver, and nickel plating. It primarily serves as a配套 component for aviation plugs, new energy connectors, wire harness terminals, and sensors.
The company’s standard elastic clips, mature mass-produced universal hardware accessories, are manufactured using one-piece stamping and bending processes followed by quenching treatment. This combination provides both hardness and elasticity, ensuring stable clamping force and resistance to loosening. With complete specifications and ample stock, these clips support multi-material customization and anti-rust wear-resistant 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.
Customization Capabilities and Service Advantages
Beyond its core product lines, Nanpi Haokai Hardware offers comprehensive non-standard customization services for metal stamping, CNC machining, and injection molded parts. Leveraging its complete set of independent production equipment and professional technical team, the company provides end-to-end services including product drawing optimization, prototype production, mass production, and after-sales follow-up. This integrated approach ensures consistent product quality and efficient delivery timelines.
The company’s customization process begins with detailed consultation to understand customer requirements, followed by professional design and engineering support. Production samples undergo rigorous testing and validation before mass production commences. Throughout the manufacturing process, quality control measures are implemented at each stage to maintain high standards. After delivery, the company provides responsive after-sales service to address any concerns or requirements.
Nanpi Haokai’s commitment to customer satisfaction extends to its flexible production capabilities. The company supports both small-batch sampling and large-scale mass production, with minimum order quantities starting from just 100 pieces for certain products. This flexibility enables customers to test market viability without significant upfront investment while having the option to scale up production as demand grows.
