Nanpi Haokai Hardware Products Co., Ltd., strategically located near Bohai Bay and just 1 kilometer from the Beijing-Shanghai Expressway, has established itself as a leading professional manufacturer in China’s metal processing industry. With over two decades of continuous innovation and development, the company has built a comprehensive production system integrating design, R&D, manufacturing, sales, and after-sales service for metal products.
Advanced Manufacturing Capabilities
The company’s production facilities represent the cutting edge of metal processing technology in China. With over 30 stamping machines ranging from 30 to 250 tons, and more than 30 CNC machining centers including automatic lathes and CNC walking machines, Haokai Hardware maintains exceptional processing precision and efficiency. The injection molding department complements this with advanced equipment for producing high-quality plastic components.
A dedicated team of 70 professionals, including 16 technical engineers and 7 senior technicians, ensures that every production process meets stringent quality standards. The company’s ISO9001:2015 certification underscores its commitment to quality management systems, with continuous improvement being a core principle of daily operations.
Core Product Lines
Haokai Hardware specializes in three main product categories, each offering extensive customization options to meet diverse industrial requirements:
1. Precision Stamping Parts
The company’s metal shovel series exemplifies its stamping expertise. Manufactured through single-piece stretching and bending from whole metal sheets, these products feature no welds or joints, ensuring exceptional durability. The integrated reinforcement ribs and smooth arc surfaces enable efficient material handling while preventing deformation. Customers can specify materials including cold-rolled steel, stainless steel, aluminum alloy, and copper, with standard mounting holes for easy installation.
Another star product in this category is the precision-rolled and zinc-plated bushing. Produced through CNC turning, these bushings feature smooth inner walls and precise dimensions. The middle knurling pattern significantly increases friction during assembly, preventing loosening during operation. After zinc plating treatment, they demonstrate excellent corrosion resistance, making them ideal for fasteners, wire harness connectors, and instrument bushings.
2. CNC Machined Components
The brass connecting rod series showcases Haokai’s precision machining capabilities. These one-piece components feature exact dimensions and smooth surfaces without burrs, ensuring smooth insertion and removal. Made from high-quality brass, they offer excellent electrical and thermal conductivity while resisting oxidation and corrosion. The company can substitute materials including phosphor bronze, red copper, aluminum, and iron, with customizable dimensions, structures, and surface treatments like tin or zinc plating.
For applications requiring even higher precision, the brass stretched copper shell (connector terminal housing) provides an ideal solution. These seamless, compact components feature precise positioning and smooth operation. Available in various copper alloys, they support custom surface treatments including gold, silver, or nickel plating for specialized applications like aviation connectors and sensor assemblies.
3. Injection Molded Parts
While primarily known for metal processing, Haokai’s injection molding capabilities complement its product range perfectly. The standard elastic clip series demonstrates this versatility. Manufactured through one-piece stamping and bending with quenching treatment, these clips balance hardness and elasticity for reliable clamping force. Available in multiple materials with anti-rust surface treatments, they serve as universal fasteners for electrical appliances, pipes, and precision instruments.
Industry Applications
Haokai Hardware’s products serve multiple industries with their customizable nature and reliable performance:
- Automotive Industry: Custom components for engine systems, electrical connectors, and structural parts
- Electronics Sector: Precision terminals, connectors, and housing components for consumer electronics
- Medical Equipment: Corrosion-resistant parts meeting strict hygiene standards for medical devices
- Renewable Energy: Durable components for solar panel mounting systems and wind turbine assemblies
- Industrial Machinery: High-strength parts for various mechanical equipment and tooling
The company’s ability to customize materials, dimensions, and surface treatments makes it particularly valuable for applications with special requirements. For instance, its brass components find extensive use in marine environments due to their excellent corrosion resistance, while aluminum parts serve weight-sensitive applications in the aerospace sector.
Customization Process
Haokai Hardware’s customization services follow a structured process to ensure customer requirements are met precisely:
| Process Stage | Key Activities |
|---|---|
| Requirement Analysis | Understand application environment, functional requirements, and material preferences |
| Design Optimization | Engineering team improves design for manufacturability and cost efficiency |
| Prototype Production | Create samples for functional testing and customer approval |
| Mass Production | Implement optimized processes for consistent quality at scale |
| Quality Control | 100% inspection for critical dimensions and functional tests |
This comprehensive approach enables Haokai to handle orders ranging from small prototype batches to large-scale production runs efficiently. The company’s flexible production system can accommodate both simple parts and complex assemblies requiring multiple processing steps.
FAQ
What types of materials can you process for custom metal parts?
We work with a wide range of materials including various steels (cold-rolled, stainless), aluminum alloys, copper alloys (brass, phosphor bronze, red copper), and engineering plastics. Our material selection considers factors like mechanical properties, corrosion resistance, and cost requirements for each specific application.
How do you ensure dimensional accuracy for CNC machined components?
Our CNC machines feature high-precision servo systems and ball screws for accurate positioning. We implement strict process controls including regular equipment calibration, in-process inspection, and final dimensional verification using advanced measuring instruments like CMMs (Coordinate Measuring Machines).
What is your minimum order quantity for custom parts?
We accommodate both small and large orders. For custom stamping parts, we can produce as few as 100 pieces for initial samples or prototypes. For CNC machined components, the minimum order quantity typically starts at 50 pieces, depending on part complexity. We also offer cost-effective solutions for larger production volumes.
How long does it take to produce custom metal parts?
Lead times vary based on part complexity and order quantity. Simple stamping parts typically take 15-20 days from design approval to delivery, while more complex CNC machined components may require 25-30 days. We maintain clear communication throughout the production process and can expedite orders when necessary.
