Core Product Offerings
As a specialized manufacturer, we focus on three primary product categories that address diverse industrial needs:
1. Precision Stamping Components
Our metal shovel exemplifies our stamping expertise. Manufactured from single-piece material through stretching and bending processes, this product features no welds or joints, ensuring exceptional durability. The integrated reinforcement ribs and smooth, rounded edges facilitate efficient material handling while preventing deformation. Standard mounting holes simplify installation, eliminating the need for secondary processing by customers and reducing overall production costs.
We offer customization options including various materials (cold-rolled steel, stainless steel, aluminum alloy, copper), dimensions, and finishes to suit specific application requirements. This product finds extensive use in industrial equipment, construction machinery, and agricultural implements where reliable performance under heavy loads is essential.
2. CNC Machined Components
Our brass connecting rods demonstrate our CNC machining capabilities. Produced as single-piece components with precise dimensions and smooth surfaces, these rods ensure seamless insertion and removal without sticking. Made from high-quality brass, they offer excellent electrical and thermal conductivity while resisting oxidation and corrosion.
Customization options extend beyond material selection (phosphor copper, red copper, aluminum, iron) to include dimensional adjustments, structural modifications, and various surface treatments like tin plating, zinc plating, and polishing. These versatile components serve critical roles in connectors, automotive parts, renewable energy equipment, medical instruments, and electrical terminals where reliable electrical connections are paramount.
3. Injection Molded Parts
The precision knurled zinc-plated sleeves highlight our injection molding expertise. CNC-turned for smooth walls and accurate dimensions, these sleeves feature middle knurling that significantly increases friction during assembly, preventing slippage during operation. The zinc plating provides excellent corrosion resistance, extending product lifespan in demanding environments.
We accommodate various material requests (iron, stainless steel, brass, aluminum) and offer multiple surface treatments. Customization options include diameter, length, and wall thickness specifications, making these sleeves ideal for fasteners, wire harness connectors, instrument bushings, furniture hardware, and mechanical positioning applications across diverse industries.
Customization Capabilities and Service Advantages
What sets Nanpi Haokai apart is our comprehensive customization service that addresses unique client requirements. Whether you need components based on drawings, samples, small prototype runs, or large-scale production, our team works closely with you to optimize designs for manufacturability and cost-effectiveness.
Our service process includes:

Industry Applications and Success Stories
Our components serve critical functions across multiple sectors:
- Renewable Energy: Custom connectors for solar panel arrays and wind turbine components
- Automotive: Precision parts for engine systems, transmission components, and electrical connectors
- Electronics: Miniature components for consumer devices, industrial controls, and telecommunications equipment
- Medical: Sterilizable parts for diagnostic equipment, surgical instruments, and monitoring devices
- Instrumentation: Durable components for measurement devices, control panels, and testing equipment
One notable project involved developing specialized connectors for a leading European renewable energy company. By collaborating closely with their engineering team, we optimized the design for both performance and manufacturability, resulting in a 40% cost reduction while improving connection reliability by 25%. This successful partnership led to long-term contracts and references that continue to attract new clients in the energy sector.
FAQ
What materials can you use for custom high voltage bobbins?
We offer comprehensive material options including various plastics (PA66, PBT, PET), metals (cold-rolled steel, stainless steel, aluminum, copper), and specialized alloys. Our engineers can recommend the optimal material based on your application’s electrical, thermal, and mechanical requirements.
How do you ensure dimensional accuracy in CNC machined components?
Our quality control system incorporates three layers of inspection: raw material verification, in-process monitoring using CMM (Coordinate Measuring Machines), and final inspection before packaging. This ensures all components meet the specified ±0.01mm tolerance for critical dimensions.
What is your minimum order quantity for custom stamping parts?
We accommodate both small and large production runs. Our MOQ starts at 100 pieces for simple designs, while complex components may require a minimum of 500 pieces. We also offer prototype services with quantities as low as 1-10 pieces for design verification.
How long does it typically take to produce custom components?
Production timelines depend on component complexity and order volume. Simple parts can be produced within 7-10 days after design approval, while more complex items may require 15-20 days. We maintain clear communication throughout the process to meet your delivery requirements.
Do you provide design assistance for custom projects?
Absolutely. Our engineering team offers free design consultation services to optimize your components for manufacturability and cost-efficiency. We can suggest material alternatives, structural improvements, and process optimizations based on our extensive production experience.
