Located in the strategic industrial hub near Bohai Sea and Beijing-Tianjin region, Nanpi Haokai Hardware Products Co., Ltd. has established itself as a premier manufacturer of custom conductive terminals and precision metal components over the past two decades. With proximity to the Beijing-Shanghai Expressway (just 1km away), our company combines geographical advantages with technical expertise to deliver superior metal fabrication solutions for global clients.
Comprehensive Manufacturing Capabilities
Our 3,000㎡ production facility houses state-of-the-art equipment including 30+ stamping presses (30-250 tons), 30+ CNC machining centers (including automatic lathes and Swiss-type CNC machines), and advanced injection molding machines. This equipment arsenal enables us to handle projects ranging from prototype development to mass production with consistent quality.
The 70-strong workforce includes 16 technical professionals and 7 senior technicians, ensuring every project benefits from specialized expertise. Our integrated production system covers product design, tooling fabrication, precision machining, surface treatment, and quality inspection – all under one roof. This vertical integration allows us to maintain strict control over production timelines and product specifications.
Core Product Lines
As a specialized conductive terminal manufacturer, we offer three primary product categories with extensive customization options:
1. Precision Stamped Conductive Terminals
Our flagship stamping capabilities produce complex terminal shapes with tolerances of ±0.02mm. The metal shovel series exemplifies our precision engineering – manufactured from single metal sheets through progressive die stamping, these components feature reinforced structures, smooth contours, and pre-punched mounting holes that eliminate secondary processing for customers. Available in cold-rolled steel, stainless steel, aluminum, and copper alloys, these terminals withstand demanding industrial environments while reducing assembly costs.
2. CNC Machined Conductive Components
The brass connecting rod series demonstrates our CNC machining precision. Manufactured from high-conductivity brass (or alternative materials like phosphor copper, aluminum, etc.), these components feature:
- Dimensional accuracy within ±0.01mm
- Surface roughness below Ra0.8μm
- Customizable plating options (tin, zinc, nickel, etc.)
- Design flexibility for various connector applications
These properties make them ideal for automotive harness systems, renewable energy equipment, and medical device connectors where reliable electrical performance is critical.
3. Non-Standard Custom Hardware
Our knurled zinc-plated sleeves showcase specialized manufacturing capabilities. Produced through CNC turning with:
- Middle knurling for enhanced friction
- Zinc plating for corrosion resistance
- Material options including steel, stainless steel, brass
- Customizable dimensions (OD/ID/length)
These components solve assembly challenges in fastening systems, instrument bushings, and mechanical positioning applications across industries.
Quality Assurance System
Implementing ISO 9001:2015 standards throughout our operations, we maintain rigorous quality control protocols:
| Quality Stage | Control Measures |
|---|---|
| Incoming Materials | Spectral analysis, hardness testing, salt spray testing |
| In-Process | First-article inspection, SPC process control |
| Final Inspection | Dimensional measurement, functional testing, packaging audit |
Our quality team utilizes advanced testing equipment including CMM coordinate measuring machines, projectors, and material analyzers to ensure every component meets specifications before shipment.
Customization Process
We streamline custom projects through our 5-step development system:
- Requirement Analysis: Technical team reviews drawings/samples to identify critical dimensions and performance requirements
- Design Optimization: DFM (Design for Manufacturing) suggestions to improve producibility and reduce costs
- Prototype Production: Rapid tooling fabrication and sample delivery within 7-15 days
- Testing Validation: Functional testing per customer specifications
- Mass Production: Scalable manufacturing with consistent quality control
This systematic approach enables us to complete custom projects 30% faster than industry average while maintaining 99.8% on-time delivery rate.
Industry Applications
Our conductive terminals and precision components serve diverse markets:
- Automotive: Battery connectors, ECU terminals, sensor housing
- Electrical: Power distribution terminals, switch contacts
- Renewable Energy: Solar inverter connectors, wind turbine components
- Medical: Diagnostic equipment connectors, surgical tool components
- Industrial: Control system terminals, motor connectors
FAQ
What materials are available for custom conductive terminals?
We offer comprehensive material options including brass (C2680, C3604), phosphor copper (C5191), stainless steel (304, 316), aluminum (6061, 6063), and various steel alloys. Material selection depends on conductivity requirements, corrosion resistance needs, and budget considerations.
How does your company ensure dimensional accuracy?
Three key measures maintain precision: 1) High-precision CNC equipment with ±0.005mm repeatability 2) Regular machine calibration and maintenance 3) In-process inspection using CMM and optical comparators. All critical dimensions are 100% inspected before shipment.
What is your minimum order quantity for custom parts?
We accommodate both prototype and mass production needs. For stamped components, MOQ starts at 1,000 pieces; for CNC machined parts, we accept orders from 100 pieces. Small batch production uses dedicated fixtures to maintain cost-effectiveness.
How long does custom development typically take?
Project timelines vary by complexity:
– Simple stamping parts: 7-10 days for samples
– Complex CNC components: 10-15 days for prototypes
– Multi-process assemblies: 15-20 days for initial samples
Mass production usually begins within 3 days after sample approval.
What surface treatments are available?
Our surface finishing capabilities include:
– Plating: Tin, nickel, zinc, silver, gold
– Anodizing: Clear, black, colored
– Passivation: For stainless steel
– Polishing: Mirror or satin finishes
– Powder coating: Various colors
– Painting: Custom color matching
All treatments comply with RoHS and REACH standards.
