The injection molding department complements our metalworking capabilities with 30 sets of modern equipment capable of producing high-precision plastic components. This integrated approach allows us to offer complete assembly solutions that combine metal and plastic parts, reducing our clients’ supply chain complexity and improving time-to-market for their products.
Our quality management system, certified to ISO 9001:2015 standards, ensures consistent product quality across all manufacturing processes. From raw material inspection to final product testing, we implement strict quality control measures at every stage of production. This commitment to quality has earned us long-term partnerships with major enterprises in automotive, medical, energy, and instrumentation sectors.
Core Product Lines and Customization Services
Nanpi Haokai Hardware specializes in several key product categories that serve diverse industrial applications:
1. Precision Metal Stamping Components
Our metal stamping capabilities produce components for various industries with exceptional precision and consistency. One of our flagship products is the industrial metal shovel, manufactured through one-piece stretching and bending from solid metal sheets. This design eliminates welds and joints, resulting in superior strength and durability. The shovel features reinforced ribs, smooth rounded edges, and standard mounting holes for easy assembly without secondary processing.
We offer customization options including material selection (cold-rolled steel, stainless steel, aluminum alloy, copper), dimensional adjustments, and surface treatments. These shovels find applications in industrial equipment, construction machinery, and material handling systems worldwide.
2. CNC Machined Components
Our CNC machining services produce high-precision components like the brass connector rod, which features one-piece molding for exact dimensional accuracy and smooth surface finish. Made from high-quality brass with excellent conductivity and corrosion resistance, these rods serve as critical electrical connectors in automotive, energy, and medical equipment.
We offer material substitutions including phosphor copper, red copper, aluminum, and iron, along with customizable dimensions, structures, and surface treatments like tin plating, zinc plating, and polishing. Our CNC capabilities ensure consistent quality even for complex geometries and tight tolerances.
3. Custom Injection Molded Parts
While not our primary focus, our injection molding capabilities complement our metalworking services by producing high-precision plastic components. This allows us to offer integrated solutions that combine metal and plastic parts, particularly valuable for clients needing complete assemblies rather than individual components.
Specialized Components for Demanding Applications
Beyond our core product lines, we manufacture several specialized components that address specific industry challenges:
- Precision Knurled Zinc-Plated Bushings: These non-standard hardware components feature smooth tube walls and precise dimensions achieved through CNC turning. The middle knurling pattern significantly increases assembly friction to prevent slippage during equipment operation. After zinc plating for corrosion resistance, these bushings demonstrate exceptional durability in applications like fasteners, wire harness connectors, and mechanical positioning.
- Brass Stretched Copper Shells: Manufactured through precision stamping and stretching, these connector terminal housings offer seamless construction with compact structure and precise positioning. The high-quality copper material ensures stable conductivity and excellent corrosion resistance, making them ideal for aviation plugs, new energy connectors, and sensor applications. We offer material substitutions and premium surface treatments like gold, silver, and nickel plating.
- Standard Elastic Clips: These mature mass-produced general-purpose hardware accessories feature one-piece stamping and bending with quenching treatment for optimal hardness and elasticity. Available in various materials with anti-rust surface treatments, they provide stable clamping force for electrical appliances, pipes, precision instruments, and industrial equipment assembly.

Full-Service Customization Capabilities
What truly sets Nanpi Haokai Hardware apart is our comprehensive customization service that covers the entire product lifecycle. From initial design consultation to final delivery, we work closely with clients to transform their concepts into high-quality industrial components.
Our process begins with detailed discussions to understand your specific requirements, including application environment, performance expectations, and budget constraints. Our engineering team then develops optimized solutions that balance functionality, manufacturability, and cost-effectiveness.
For new designs, we offer rapid prototyping services that allow you to evaluate form, fit, and function before committing to full production. Our advanced equipment enables quick turnaround times without compromising precision, helping you accelerate your product development cycle.
During mass production, our quality control system monitors every batch to maintain consistent standards. We implement statistical process control (SPC) methods to detect and correct variations early in the production process, ensuring every component meets your specifications.
Our service doesn’t end with delivery. We provide comprehensive after-sales support, including technical assistance, warranty service, and feedback analysis to continuously improve our products and processes based on real-world performance.
FAQ
What types of materials can you work with for custom metal components?
We have extensive experience working with various metals including stainless steel, carbon steel, aluminum alloys, copper alloys (brass, bronze), and specialty alloys. Our material selection depends on your specific application requirements for strength, corrosion resistance, conductivity, and cost considerations.
How do you ensure dimensional accuracy for CNC machined components?
Our CNC machines are equipped with high-precision servo systems and are regularly calibrated to maintain accuracy within ±0.01mm. We use advanced measurement equipment like CMM (Coordinate Measuring Machines) for final inspection and implement statistical process control throughout production to monitor and maintain quality standards.
What is your minimum order quantity for custom stamping parts?
We accommodate both small and large production runs. For new custom stamping projects, we typically recommend starting with a prototype batch of 50-100 pieces for evaluation. For formal production, our MOQ is usually 500-1,000 pieces depending on component complexity, though we can discuss smaller quantities for specialized applications.
How do you handle design modifications during production?
We understand that design refinements may be necessary during development. Our flexible production system allows for design changes with minimal disruption. For minor modifications, we can often implement them without significant delay. For major changes, we’ll work with you to assess the impact on tooling, lead time, and cost before proceeding.
What quality certifications do your products comply with?
Our quality management system is certified to ISO 9001:2015 standards. Many of our components also comply with industry-specific standards such as RoHS for environmental compliance, REACH for chemical safety, and various ASTM/DIN/JIS material standards depending on the application. We can provide material test reports and certification documents upon request.
