Specialized Low-Volume Machining Factory | Black Nitride Steel Components & Precision Carbon Steel Parts
We are a precision metal parts manufacturer based in Huizhou, Guangdong, China, with our own factory and a team of 20 experienced technicians.
With years of experience serving international clients, we understand the common challenges in prototyping and low-volume production:
• Complex part structures
• Multiple material combinations
• Tight tolerance requirements
• Limited supplier flexibility for small-batch, high-mix orders
We focus on solving these challenges with flexible production and reliable engineering support.
Welded Carbon Steel CNC Turned Component
Recently, we successfully delivered a welded assembly carbon steel CNC turned part for an industrial client. The project highlights our ability to handle complex manufacturing requirements:
Dissimilar Metal Welding
• Base: 1215 free-cutting carbon steel
• Pin shaft: High-strength alloy steel
Through a mature welding process, we ensured:
• Stable tensile strength exceeding 200 kg
• Reliable performance under demanding load conditions
Ultra-Precision Machining
• Shaft outer diameter tolerance controlled within ±0.005 mm
• Surface roughness: Ra 0.4
After assembly testing, the component demonstrated:
• Excellent wear resistance
• Long fatigue life (over 20,000 hours)
QPQ Surface Treatment (Black Nitride Finish)
To meet both corrosion resistance and wear resistance requirements, we applied QPQ (Quench-Polish-Quench) treatment.
This process produces high-performance black nitride steel components with the following advantages:
• Increased surface hardness
• Excellent corrosion resistance
• Minimal deformation after treatment
It effectively overcomes the common rust issues associated with carbon steel parts.
