Our integrated production system covers design, prototyping, mass production, and after-sales service, providing a seamless experience for clients worldwide.
Core Product Lines and Customization Capabilities
Our product portfolio focuses on three main categories of custom metal components, each offering unique advantages for industrial applications:
1. Precision Metal Stamping Parts
Our metal stamping capabilities include complex shapes with tolerances as tight as ±0.02mm. The metal shovel, one of our flagship stamping products, demonstrates our expertise in this area. Manufactured through one-piece stretching and bending from solid plate material, these shovels feature no seams or welds, ensuring exceptional durability and resistance to bending or cracking. The integrated reinforcement ribs and smooth arc-shaped surfaces provide optimal material handling performance while standard mounting holes simplify installation.
Customization options for our stamping parts include material selection (cold-rolled steel, stainless steel, aluminum alloy, copper, etc.), dimensional adjustments, and various surface treatments. This flexibility allows us to create components that perfectly match specific equipment and operating environments across industries.
2. CNC Machined Components
Our CNC machining services produce components with exceptional precision and surface quality. The brass connecting rod exemplifies our capabilities in this area, featuring one-piece molding with dimensional accuracy to ±0.01mm and surface roughness below Ra0.8. Made from high-quality brass with excellent electrical and thermal conductivity, these components resist oxidation and corrosion while providing smooth insertion and removal.
We offer extensive customization for CNC machined parts, including material substitution (phosphor copper, red copper, aluminum, iron, etc.), dimensional adjustments, structural modifications, and various surface treatments like tin plating, zinc plating, and polishing. These options make our components suitable for demanding applications in connectors, automotive parts, new energy equipment, medical instruments, and electrical terminals.
3. Non-Standard Custom Hardware
Understanding that many industrial applications require unique solutions, we specialize in producing non-standard custom hardware components. Our precision knurled galvanized sleeves (metal bushings) demonstrate this capability perfectly. Manufactured through CNC turning, these sleeves feature smooth inner walls, precise dimensions, and a knurled middle section that significantly increases assembly friction to prevent slippage during operation.
The galvanized finish provides excellent corrosion resistance, extending service life in challenging environments. We can customize these bushings with various materials (iron, stainless steel, brass, aluminum), surface treatments, and dimensional specifications to suit applications in fasteners, wire harness connectors, instrument bushings, furniture hardware, and mechanical positioning systems.

Industry Applications and Solutions
Our custom metal components serve diverse industries including new energy, automotive, electrical appliances, medical equipment, instrumentation, and mechanical manufacturing. For each sector, we develop specialized solutions that address specific operational challenges:
In the automotive industry, our components contribute to vehicle safety and performance. The brass stretching copper shell (connector terminal housing) provides a perfect example. This precision stamping and stretching product offers seamless construction, compact structure, and precise positioning for reliable electrical connections in automotive applications. The high-quality copper material ensures stable conductivity and excellent corrosion resistance, while customization options allow adaptation to various connector designs.
For the medical equipment sector, we produce components with stringent quality requirements. Our CNC machined parts feature biocompatible materials when needed and undergo special cleaning processes to meet medical industry standards. The precision and reliability of our manufacturing processes ensure components that perform consistently in critical medical applications.
The new energy industry presents unique challenges with its combination of high-voltage systems and harsh operating environments. Our components for this sector feature enhanced insulation properties, corrosion resistance, and dimensional stability under temperature extremes. The brass connecting rods, for example, provide reliable electrical connections in solar inverter systems and wind turbine control units.

FAQ
What types of custom metal components can Nanpi Haokai manufacture?
We specialize in three main categories: precision metal stamping parts, CNC machined components, and non-standard custom hardware. Our capabilities include complex shapes with tight tolerances, one-piece constructions without seams or welds, and components with specialized features like knurled surfaces or integrated reinforcement structures. We can produce parts from various materials including metals and plastics, with customization options for dimensions, tolerances, and surface treatments.
How does your company ensure the quality of custom metal components?
Quality assurance is integral to our manufacturing process. We follow ISO 9001:2015 standards throughout production, with quality checks at every stage from material inspection to final packaging. Our equipment includes advanced measurement tools like CMM (Coordinate Measuring Machines) for precise dimensional verification. We also maintain complete traceability records and offer third-party inspection services when required by customers.
What is your minimum order quantity for custom components?
We accommodate both small-batch prototypes and large-volume production runs. Our minimum order quantity depends on the complexity of the component and required production processes. For simple stamping parts, we can accept orders as small as 100 pieces, while more complex CNC machined components might have higher MOQs. We also offer sample production services to help customers validate designs before full-scale manufacturing.
How long does it typically take to produce custom metal components?
Production timelines vary based on component complexity, order quantity, and current production capacity. For simple stamping parts, lead times can be as short as 7-10 days for small batches after design finalization. More complex CNC machined components typically require 15-20 days for production. We work closely with customers to establish realistic schedules and provide regular progress updates throughout the manufacturing process.
What material options are available for custom metal components?
We offer extensive material choices to match different application requirements. Common metal options include various grades of steel (cold-rolled, stainless, etc.), aluminum alloys, brass, copper, and titanium. For each material, we can recommend appropriate surface treatments like plating, anodizing, or painting to enhance corrosion resistance or achieve specific aesthetic requirements.
