In the competitive landscape of electrical component manufacturing, finding a reliable conductive terminal manufacturer requires evaluating technical expertise, production capacity, and quality assurance systems. South County Haokai Hardware Products Co., Ltd. has established itself as China’s premier source for precision-engineered conductive terminals through two decades of continuous innovation and customer-centric service. This comprehensive guide explores our manufacturing capabilities, core product lines, and why global enterprises trust us as their conductive terminal supplier.
Why Choose Haokai as Your Conductive Terminal Manufacturer?
Our strategic location near Bohai Bay and Beijing-Shanghai Expressway enables efficient logistics while maintaining competitive pricing. The company’s 70+ workforce includes 16 technical specialists and 7 senior technicians operating 30+ stamping machines (30-250 ton capacity) and 30+ CNC processing units including automatic lathes and injection molding machines. This infrastructure supports our integrated workflow from design to after-sales service under ISO 9001:2015 certification.
The manufacturing process combines advanced equipment with rigorous quality control:
- Material verification: Only certified copper alloys (C1100, C2680, etc.), stainless steel, and aluminum enter production
- Precision machining: CNC turning maintains ±0.01mm tolerance for critical dimensions
- Surface treatment: Electroplating options include gold, silver, nickel, tin, and zinc coatings
- Functional testing: 100% electrical continuity verification before packaging
Core Conductive Terminal Product Lines
Our product development focuses on three principal categories with extensive customization options:
1. Brass Connecting Rods (CNC Machined)
These precision-engineered components feature one-piece construction with smooth surfaces (Ra≤0.8μm) and precise dimensions (±0.02mm tolerance). The standard brass material offers excellent conductivity (≥85% IACS) and corrosion resistance, while alternative materials like phosphor bronze and aluminum accommodate specific environmental requirements. Customization extends to dimensional parameters, structural designs, and surface treatments including passivation and polishing.
Typical applications include:
- Automotive electrical connectors
- 新能源 device terminal blocks
- Medical instrument signal transmitters
- Consumer appliance power interfaces
2. Precision Knurled Galvanized Sleeves
Manufactured through CNC turning, these non-standard metal bushings feature smooth inner bores (H7 tolerance) and knurled exteriors to prevent loosening under vibration. The zinc plating provides 500+ hours salt spray resistance, while alternative materials like stainless steel and aluminum suit corrosive environments. Customization parameters include:
- Outer diameter: 6-50mm
- Length: 10-200mm
- Wall thickness: 1-10mm
- Surface finish: Polishing, anodizing, or chromating
These components excel in:
- Mechanical positioning systems
- Wire harness connectors
- Furniture hardware assemblies
- Industrial equipment bearings
3. Brass Stretched Shells (Terminal Housings)
Our deep-drawing process creates seamless housings with consistent wall thickness (±0.05mm) and precise alignment features. The copper material ensures stable conductivity (>90% IACS) while resisting oxidation in temperatures up to 200°C. Surface treatment options include:
- Electroless nickel plating (4-8μm)
- Selective gold plating (0.2-1μm)
- Passivation for marine environments
Key applications:
- Aviation plug connectors
- 新能源 battery terminals
- Sensor interface housings
- High-voltage equipment shields

FAQ
What minimum order quantities do you accept for custom conductive terminals?
Our MOQ starts at 500 pieces for standard designs and 1,000 pieces for fully customized components. Small-batch prototyping (10-100pcs) is available at adjusted pricing.
How do you ensure electrical conductivity in multi-material assemblies?
We implement three quality control measures:
- Material certification verification for each batch
- In-process conductivity testing using micro-ohmmeters
- Final inspection with Hi-Pot testers (2,000V AC)
What lead time should I expect for custom terminal production?
Typical timelines:
- Design review: 2-3 business days
- Prototyping: 5-7 days
- Tooling fabrication: 10-15 days
- Mass production: 15-25 days (depending on volume)
Expedited services reduce timelines by 30% for urgent orders.
Can you match existing terminal dimensions from other manufacturers?
Yes. Our reverse engineering capabilities include 3D scanning, dimensional analysis, and material composition testing to create drop-in replacements or improved versions of legacy components.
What certifications do your conductive terminals comply with?
All products meet:
- ISO 9001:2015 quality management
- RoHS 2.0 (Restriction of Hazardous Substances)
- REACH (Registration, Evaluation, Authorisation of Chemicals)
- UL 94 V-0 flammability rating (upon request)
We provide material test reports (MTRs) and certificates of compliance (CoCs) with each shipment.
