In the competitive landscape of industrial metal component manufacturing, finding a reliable partner that combines precision engineering with customized solutions is crucial for businesses worldwide. Nanpi Haokai Hardware Products Co., Ltd., located near Bohai Sea and just 1km from the Beijing-Shanghai Expressway, has established itself as a premier manufacturer specializing in custom battery contact plates, precision metal stamping parts, and CNC machined copper components. With over two decades of experience in the metalworking industry, the company has developed a comprehensive approach to meeting diverse industrial needs through advanced technology, skilled craftsmanship, and strict quality control.

Core Manufacturing Capabilities
Nanpi Haokai’s production facilities represent the pinnacle of modern metalworking technology. The company operates more than 30 stamping machines ranging from 30 to 250 tons, enabling precise fabrication of components with varying complexity and size requirements. This extensive stamping capacity is complemented by over 30 CNC machining centers, including automatic lathes and CNC walking core machines, which allow for high-precision manufacturing of copper components and other specialized metal parts.
The company’s technical team comprises 16 professional technicians and 7 senior mechanics, ensuring that every production process benefits from expert supervision and problem-solving capabilities. This technical expertise is particularly valuable when handling custom orders that require non-standard specifications or innovative design solutions. The integration of advanced equipment with skilled personnel creates a production environment capable of delivering components with tolerances as tight as ±0.01mm, meeting the most demanding industry standards.
Product Range and Customization Options
Nanpi Haokai specializes in three main product categories: precision stamping parts, CNC machined components, and injection-molded parts. Within these categories, the company offers extensive customization options to meet specific customer requirements across various industries.
The battery contact plate series exemplifies the company’s customization capabilities. These components can be manufactured from multiple materials including cold-rolled steel, stainless steel, aluminum alloy, and copper, with thickness options ranging from 0.2mm to 5.0mm. Surface treatments such as nickel plating, tin plating, and zinc plating are available to enhance conductivity and corrosion resistance. The company’s ability to produce components with dimensions up to 600mm×400mm and precision up to ±0.05mm makes them suitable for diverse applications in the automotive, electrical, and renewable energy sectors.

Specialized Battery Components
For battery manufacturing applications, Nanpi Haokai offers specialized solutions including battery compression plates and copper conductive sheets. The battery compression plates feature a unique design with reinforcing ribs and smooth arc surfaces that facilitate efficient material handling while preventing deformation during assembly. Standard mounting holes eliminate the need for secondary processing, reducing production costs for customers.
The copper conductive sheets represent another area of specialization, with the company’s yellow copper connecting rods serving as a prime example. These components are manufactured through integral forming processes that ensure dimensional accuracy and surface smoothness. The use of high-quality copper material provides excellent electrical and thermal conductivity while offering superior oxidation resistance compared to standard alternatives. Customization options include material substitution (phosphor copper, red copper, aluminum, iron) and various surface treatments like tin plating, zinc plating, and polishing.
Quality Management System
Nanpi Haokai’s commitment to quality is formalized through its ISO 9001:2015 certification, which governs every aspect of production from design to after-sales service. The company’s quality management system emphasizes continuous improvement and customer satisfaction, with procedures in place for:
- Incoming material inspection and testing
- In-process quality control at each production stage
- Final product inspection with comprehensive testing
- Documentation and traceability for all components
- Corrective and preventive action systems
This systematic approach to quality ensures that every component leaving the factory meets or exceeds customer expectations. The company’s inspection equipment includes projectors, salt spray testers, hardness testers, and tensile testing machines, enabling thorough evaluation of product performance characteristics.
| Quality Control Stage | Inspection Procedures |
|---|---|
| Incoming Materials | Chemical composition analysis, mechanical property testing, dimensional verification |
| In-Process | First-piece inspection, statistical process control, critical dimension checks |
| Final Inspection | 100% dimensional inspection, surface finish evaluation, functional testing |
| Packaging | Protection verification, quantity confirmation, labeling accuracy check |
Industry Applications and Solutions
Nanpi Haokai’s components serve diverse industries including new energy, automotive, electrical appliances, medical equipment, instrumentation, and mechanical manufacturing. The company’s ability to customize solutions for specific applications has made it a preferred supplier for many international corporations.
In the automotive sector, the company’s precision components are used in battery systems, connectors, and electrical terminals, where reliability and performance are critical. For renewable energy applications, custom-designed copper busbars and conductive sheets support efficient power transmission in solar and wind energy systems. The medical equipment industry benefits from the company’s ability to produce components with strict tolerance requirements and biocompatible surface finishes.

FAQ
What materials can be used for custom battery contact plates?
We offer battery contact plates in multiple materials including cold-rolled steel, stainless steel, aluminum alloy, and copper. Each material provides different advantages – copper offers excellent conductivity, stainless steel provides superior corrosion resistance, and aluminum offers lightweight properties with good conductivity. Our engineers can recommend the most suitable material based on your specific application requirements.
How does your company ensure dimensional accuracy in CNC machined components?
Dimensional accuracy is maintained through several measures: 1) Using high-precision CNC equipment with ±0.01mm tolerance capabilities, 2) Implementing statistical process control during production, 3) Conducting first-piece inspection and in-process checks, 4) Performing final inspection with coordinate measuring machines (CMM), and 5) Maintaining regular equipment calibration. Our quality system ensures every component meets specified dimensions before shipment.
What surface treatment options are available for metal components?
We provide various surface treatments to enhance component performance: nickel plating for corrosion resistance and wear reduction, tin plating for improved solderability and conductivity, zinc plating for general corrosion protection, anodizing for aluminum components, and passivation for stainless steel. We can also provide specialized treatments like black oxide coating, electropolishing, and powder coating based on customer requirements.
How does your company handle custom component design requests?
Our design process begins with thorough communication to understand your specific requirements. We then create detailed 3D models and engineering drawings for your approval. For complex components, we can produce prototypes for testing and validation before full-scale production. Our engineering team works closely with customers throughout the process to ensure the final design meets all functional, dimensional, and material requirements.
What is your minimum order quantity for custom components?
We accommodate both small and large production runs. For custom components, our minimum order quantity typically starts at 1,000 pieces, though this may vary depending on component complexity and production requirements. We also offer prototype and small-batch production services to help customers validate designs before committing to larger volumes. Our flexible production capabilities allow us to scale efficiently as your needs grow.
