Comprehensive Technical Overview<\/span><\/h3>\n

 <\/p>\n

Our welded and drawn manufacturing process is designed to eliminate the seam performance differential completely, achieving a fully homogenous grain structure that matches or rivals seamless tubing at a more competitive cost structure. Through severe cold-drawing over a mandrel (plug drawing), the weld zone is completely recrystallized, resulting in exceptional dimensional uniformity, ultra-thin walls, and mirroring inner surfaces.<\/p>\n

Why Choose LIJ Welded & Drawn Tubing?<\/span><\/h3>\n

<\/h4>\n
    \n
  • Standard dimensional tolerances controlled down to \u00b10.01mm (\u00b10.0004″), with capabilities reaching \u00b10.005mm for customized ultra-fine high-end applications.<\/li>\n
  • Smooth inner diameter (ID) roughness down to Ra \u22660.4 \u00b5m, minimizing friction, preventing fluid turbulence, and ensuring smooth sensor wire or stylet insertion.<\/li>\n
  • Optimized tensile strength and elongation profiles, ensuring the tube can undergo secondary fabrication processes such as 3-bevel grinding, micro-flaring, laser slotting, and bending without cracking or structural failure.<\/li>\n
  • Full compliance with ASTM A908 standards. Every batch is supplied with comprehensive Material Test Certificates (MTC), RoHS, and REACH verification records.<\/li>\n<\/ul>\n

    Critical Medical & Surgical Applications<\/span><\/h3>\n

     <\/p>\n

    Due to its flawless structural integrity, uniform wall thickness, and precise concentricity, our welded & drawn stainless steel micro-tubing serves as the primary component for numerous cutting-edge medical devices globally:<\/p>\n

    \n

    Continuous Glucose Monitoring (CGM) Systems<\/strong><\/p>\n

      \n
    • Engineered to serve as the ultra-thin, precise CGM sensor introducer needles (introducer\/inserter cannulas)<\/b>. Our micro-tubing undergoes specialized thin-walled drawing to achieve the necessary rigidity at thickness levels down to 0.06mm, ensuring seamless sensor deployment under the skin with minimized patient trauma.<\/li>\n<\/ul>\n

      Advanced Catheter & Endoscopic Delivery Systems<\/strong><\/p>\n

        \n
      • Used as the internal stiffening stylets, hypotubes, and structural shafts for vascular intervention catheters, neurovascular micro-catheters, and endoscopic surgical tools. The high torque transmission and anti-kinking behavior of our hard-drawn tubing ensure optimal surgical control.<\/li>\n<\/ul>\n

        Custom Hypodermic Needles & Cannulas<\/strong><\/p>\n

          \n
        • The premium base material for high-end aesthetic microneedles, ophthalmic surgical needles, biopsy cannulas, and epidural\/spinal anaesthesia needles. The uniform concentricity allows for perfectly symmetrical 3-bevel or 5-bevel sharpening processes without causing burrs or microscopic structural tearing.<\/li>\n<\/ul>\n
