Located near Bohai Bay and adjacent to the Beijing-Shanghai Expressway, Nanpi Haokai Hardware Products Co., Ltd. has established itself as a professional private enterprise specializing in metal component design and production for over two decades. With a strong commitment to technological innovation, our company has developed a comprehensive range of high-quality hardware solutions that meet the diverse needs of global customers across multiple industries.
Comprehensive Manufacturing Capabilities
Our company boasts a complete production system covering design, R&D, manufacturing, sales, and after-sales service. With over 70 employees including 16 technical professionals and 7 senior technicians, we maintain a strong technical foundation. Our modern manufacturing facilities include more than 30 sets of stamping equipment ranging from 30 to 250 tons, along with 30 sets of CNC machines, automatic lathes, CNC sliding head machines, and injection molding machines.
The integration of advanced equipment and skilled personnel enables us to handle projects of varying complexity and scale. From small batch sampling to mass production, we ensure consistent quality through our vertically integrated production process. Our commitment to quality is underscored by our ISO 9001:2015 certification, which we maintain through rigorous quality control systems at every stage of production.
Core Product Range
Our product portfolio consists of three main series: precision stamping parts, CNC machined components, and injection molded parts. Each product category offers unique advantages tailored to specific industrial applications:
1. Precision Stamping Parts
Our metal shovels represent our advanced stamping capabilities. Manufactured through one-piece stretching and bending from whole plates without any welding, these products feature exceptional durability and resistance to bending or cracking. The integrated design includes reinforced ribs, smooth arc-shaped surfaces, and standard mounting holes for easy assembly without secondary processing, helping customers reduce production costs.
We offer customization in various materials including cold-rolled iron, stainless steel, aluminum alloy, and copper to suit different equipment and working environments. These shovels find applications in industrial assembly, material handling, and equipment maintenance across multiple sectors.
2. CNC Machined Components
Our brass connection rods exemplify our precision CNC machining capabilities. Manufactured as one-piece components with precise dimensions and smooth surfaces, these rods ensure smooth insertion and extraction without jamming. Made from high-quality brass with excellent electrical and thermal conductivity, they feature strong oxidation resistance and corrosion resistance.
We support material substitution with phosphor copper, red copper, aluminum, and iron as required, along with customization of dimensions, structures, and surface treatments including tin plating, zinc plating, and polishing. These components serve as critical electrical connections in connectors, automotive parts, new energy equipment, medical instruments, and electrical terminals.
3. Injection Molded Parts
Our precision knurled zinc sleeves (metal bushings) demonstrate our non-standard customization capabilities. Manufactured through CNC integrated turning, these sleeves feature smooth inner walls, precise dimensions, and middle knurling that significantly increases assembly friction to prevent slippage during equipment operation. The zinc plating provides excellent corrosion resistance and extends service life.
We support processing in multiple materials including iron, stainless steel, brass, and aluminum, along with various surface treatments. Customization options cover diameter, length, and wall thickness to meet diverse applications in fasteners, wire harness connectors, instrument bushings, furniture hardware, and mechanical positioning.
Customization Capabilities
Beyond our standard product range, we specialize in non-standard customization for all types of metal stamping, CNC machining, and injection molded parts. Our complete in-house production facilities and professional technical team enable us to provide comprehensive services including:
- Product drawing optimization based on customer requirements
- Prototype development and trial production
- Mass production with consistent quality control
- After-sales service and technical support
This full-service approach ensures that we can meet diverse customer needs while maintaining efficient production schedules and reliable delivery times. Our ability to handle projects from concept to completion makes us a valuable partner for companies seeking to streamline their supply chain and reduce procurement risks.
