ISO9626 SUS304 Medical Hypodermic Capillary Tube For Injection Needles Production

 

ISO9626 SUS304 Medical Hypodermic Capillary Tubes are high-precision, small-diameter hollow stainless steel micro-tubes manufactured specifically for medical device applications, most notably as the core component of hypodermic needles and other percutaneous devices. These stainless steel medical capillary tubes are characterized by extremely small diameters and thin walls. They are manufactured according to ISO9626: 2016 international standard, which governs the dimensions, tolerances, and material requirements for sterile hypodermic needles made of stainless steel tubing. Compliance ensures extreme dimensional consistency and performance reliability. SUS304 is the main raw material of medical capillary tubes due to its excellent corrosion resistance, formability, and biocompatibility.

 

Regular Sizes & Tolerances:

  • Common Outer Diameter (OD) Range: 0.18 mm – 3.4 mm (for common needle gauges: 10G-34G).
  • Common Wall Thickness (WT) Range: 0.05 mm – 0.12 mm (e.g., 0.05mm, 0.07mm, 0.09mm are typical).
  • Length: Supplied in precision-cut straight lengths (e.g., 50mm, 100mm) for specific device assembly.

 

Size Tolerances (per ISO9626):

  • Outer Diameter Tolerance: Typically ±0.005mm to ±0.01mm. For the finest gauges, tolerance can be as tight as ±0.002mm.
  • Wall Thickness Tolerance: Extremely stringent, usually within ±8% to ±10% of nominal thickness.
  • Concentricity: Critical for needle strength and beveling. Often specified to be >90% (meaning the wall thickness variation around the circumference is minimal).
  • Inner/Outer Surface Finish: Very smooth (Ra < 0.8 µm) to reduce friction during insertion and fluid flow resistance.

 

Advantages of SUS304 Medical Capillary Tubes:

  • Superior Biocompatibility & Safety: SUS304 is non-toxic, non-pyrogenic, and resistant to corrosion by bodily fluids.
  • Excellent Mechanical Properties: Enables smaller, less painful needles while maintaining structural integrity to prevent bending or buckling.
  • Good Formability: Essential for the precise bevel grinding, point forming, and hub mounting processes in needle manufacturing without cracking or delamination.
  • Consistent Dimensional Precision: ISO9626 compliance guarantees uniform fluid flow rates, predictable penetration force.
  • Cost-Effectiveness: 304 stainless offers an optimal balance of performance and manufacturability compared to more exotic alloys.

 

Applications:

1. Medical Applications:

  • Hypodermic Needles: This is the primary application, forming the cannula for single-use and safety-engineered syringes.
  • Infusion Sets & Butterfly Needles: For IV therapy.
  • Biopsy Needles: For tissue sampling.
  • Catheter Sheaths & Guidewires.
  • Ophthalmic Surgical Instruments.
  • ...

 

2. Non-Medical Applications:

  • Electronic Industry
  • Semiconductor
  • Jewelry Industry
  • Industrial Chromatography & Analytical Instrumentation: As sample lines and capillary columns.
  • Precision Fluidics: In inkjet printers, precision dispensing systems.
  • Fiber Optics & Micro-Mechanics: As protective sheathing or structural components.
  • Watchmaking & Miniature Bearings.
  • Thermocouple Sheaths.
