Flagship Product Lines
Haokai Hardware’s product portfolio addresses diverse industrial requirements through three main categories:
1. CNC Turning Components
The company’s CNC machining expertise produces components with exceptional dimensional accuracy and surface finish. Typical applications include:
- Automotive connectors and terminals
- Medical device components
- Electrical contact parts
- Precision shafts and bushings
A standout product is the brass connection rod – manufactured through precision CNC turning from high-conductivity brass. This component features smooth insertion/extraction, excellent corrosion resistance, and customizable dimensions from Ø2mm to Ø50mm with length options up to 200mm. Surface treatments include tin plating, nickel plating, and passivation to enhance performance in specific environments.
2. Precision Stamping Parts
Specializing in complex stamped components, the company produces parts with intricate geometries through progressive die stamping. Notable products include:
- Metal shovels with integrated reinforcement ribs
- Brass drawn shells for connector housings
- Standard elastic clips with consistent clamping force
- Custom battery contacts and terminals
The metal shovel exemplifies their stamping excellence – manufactured from single-piece material without welds or joints. This design ensures superior strength and durability while the pre-punched mounting holes enable direct assembly without secondary operations. Customers can specify materials from carbon steel to aluminum alloys based on application requirements.
3. Non-Standard Custom Parts
Haokai Hardware excels in producing bespoke solutions for specialized applications. Their engineering team collaborates closely with clients to develop components that precisely match functional requirements. Typical custom projects include:
- Unique instrument fittings with specific thread patterns
- Mechanical positioning components with tight tolerances
- Specialized electrical connectors with custom pin configurations
- Medical device components requiring biocompatible materials
| Product Category | Material Options | Tolerance Range |
|---|---|---|
| CNC Turning Parts | Brass, Steel, Aluminum, Stainless Steel | ±0.01mm |
| Precision Stamping | Cold Rolled Steel, Copper Alloys | ±0.05mm |
| Custom Components | As per customer specification | ±0.02mm |
Quality Assurance System
The company’s quality management system follows ISO 9001:2015 standards with comprehensive procedures covering:
- Incoming material inspection with spectral analysis
- In-process quality control using CMM measurement
- Final inspection with functional testing
- Batch traceability through unique identification codes
- Continuous improvement through customer feedback analysis
Advanced testing equipment including projectors, salt spray test chambers, and hardness testers ensure all products meet specified requirements before shipment. The quality team maintains detailed records for each production batch to facilitate quick resolution of any potential issues.
Industry Applications
Haokai Hardware’s components serve diverse industries through their reliability and precision:
