Ningbo Changfeng Mechanical Factory, an established manufacturer since 1990, specializes in delivering high-precision Custom Brass Alloy CNC Machining Parts tailored for demanding OEM machinery applications. With over three decades of expertise and an annual export value exceeding US$10 million across 15+ global markets including North America, Europe, and Asia-Pacific, we engineer solutions that enhance equipment performance and longevity. Our Ningbo-based facility leverages advanced CNC technology to transform specialized brass alloys into mission-critical components, ensuring your machinery operates with uncompromising reliability.


Our core capabilities include:

  • Material Excellence: We utilize premium brass alloys (C36000, C26000, custom blends) selected for superior machinability, corrosion resistance, and electrical conductivity. Alloy composition is optimized for specific operational stresses.

  • Precision Engineering: Multi-axis CNC machining achieves tolerances as tight as ±0.01mm, critical for high-speed rotating assemblies and fluid handling systems.

  • Complex Geometry Mastery: Capable of producing intricate features including:

    • Micro-threaded fittings

    • Internal helical channels

    • Non-standard flanges & grooves

    • Multi-plane mounting surfaces

  • Surface Enhancement Options: Optional post-processing for functional and aesthetic requirements:

    Treatment Purpose Thickness Range
    Nickel Plating Wear/Corrosion Resistance 5-25μm
    Passivation Oxidation Prevention Chemical Film
    Mirror Polishing Reduced Friction/Aesthetics Ra ≤ 0.2μm

Technical Specifications Overview:

  • Max Part Dimensions: 500mm x 300mm x 200mm (Larger upon request)

  • Standard Lead Time: 15-25 days (Prototype to bulk production)

  • Quality Assurance: 100% Dimensional Inspection + Material Certificates

  • Production Volume: Prototype (1-50pcs) to Mass Production (50,000+ pcs/month)

Frequently Asked Questions (FAQ):

  1. Q: What is your minimum order quantity (MOQ) for custom brass parts?
    A: MOQ is flexible based on part complexity. Prototype batches start from 1-5pcs, while production runs typically begin at 100pcs. We negotiate based on project scope.

  2. Q: Can you machine brass parts according to our proprietary drawings?
    A: Absolutely. We specialize in converting client-supplied CAD files (STEP, IGES, SolidWorks) or 2D drawings into precision components. Our engineers provide DFM feedback before production.

  3. Q: What lead time should we expect for first-time orders?
    A: Standard lead time is 3 weeks for tooling/sample approval + 2-3 weeks for production. Expedited services are available for urgent projects.

  4. Q: Do you provide material certification for brass alloys?
    A: Yes. Mill test certificates (MTC) confirming chemical composition and mechanical properties accompany all shipments. RoHS compliance documentation is available.

  5. Q: How do you ensure dimensional accuracy for high-precision components?
    A: We employ CMM inspection (Mitutoyo), optical comparators, and custom gauges. Statistical process control (SPC) monitors critical dimensions during production runs.

  6. Q: What packaging standards do you use for international shipments?
    A: Parts are vacuum-sealed, anti-tarnish treated, and packed in shock-absorbent containers. Wooden crates are used for heavy/large components to prevent transit damage.

  7. Q: Can you assist with secondary assembly operations?
    A: Yes. We offer value-added services including press-fitting, adhesive bonding, and sub-assembly kitting to reduce your production steps.
