Industrial Dispensing Metal/Plastic/PP/TT (Double Threaded /Single Barrel) Needles

Precision Application: Delivers 0.1mm-2.0mm bead widths with ±5% consistency

Material Optimization: Stainless steel/ETFE/Teflon coatings prevent clogging (100+ hour continuous use)

Flow Control: Tapered designs (15°-30°) enable low-pressure dispensing of 50-500,000cP fluids

    Applications:

    Key Application Scenarios:
    Electronics Assembly:
    25G-34G blunt tips for PCB conformal coating
    ESD-safe versions for static-sensitive components
    Medical Device Fabrication:
    Sterilizable 316L stainless steel needles for implant bonding
    Luer-lock connectors for disposable systems
    Automotive Manufacturing:
    14G-18G reinforced needles for glass primer application
    90° bent tips for hard-to-reach areas
    Performance Highlights:
    Ultra-Durability: Tungsten carbide tips last 3X longer than standard steel
    Smart Compatibility:
    Universal Luer slip/lock fittings (ISO 594)
    Adaptable to robotic arms via quick-change chucks
    Specialized Designs:
    Anti-static needles for conductive adhesives
    Heatable versions (200°C) for hot-melt applications
    Technical Specifications:
    Pressure Rating: 0-8bar (116psi) burst pressure
    Temp Range: -40°C to 250°C (PTFE-coated)
    Surface Finish: <0.2μm Ra for smooth material flow
    Material Grades:
    304/316L Stainless Steel: Standard corrosion resistance (0-150°C)
    Tungsten Carbide: 5X wear resistance for abrasive fillers
    PTFE-Coated: Non-stick surface for UV-curable adhesives
