Core Engineering & Rigorous Quality Performance
Comprehensive Mechanical Validation & Lot Stability
As proven by the empirical force-displacement curves and mechanical testing reports shown in image, our medical hypotube components undergo comprehensive long-term batch qualification to ensure physical performance superiority. We perform rigorous testing including: High tensile strength verification, Kink value validation, Compression force resistance profiling, Three-point bending elasticity testing, and Cyclic elasticity mapping. This continuous validation loop ensures our hypotubes provide higher stability and reliability compared to traditional international products, eliminating intraoperative shaft buckling or kinking risks.
High-Performance Multi-Color PTFE Coating & Custom Positioning Marks
To reduce the coefficient of friction to the absolute minimum, we apply specialized fluoropolymer coatings (thickness range of 6–12 μm) tightly anchored to the stainless steel substrate. Available in Black, Green, Blue, and Yellow, these coatings provide clear line visualization for multi-catheter tracking. Furthermore, we offer custom laser-etched 'Special Marks' (depth and positioning tailored per customer requirement) for real-time positional indexing during interventional procedures.
Pristine Oxide-Free Micro-Roughness Control
By utilizing high-purity medical-grade SUS304L and SUS316L stainless steel combined with advanced cold-drawing, our raw tubes maintain an oxide-free surface texture. With external roughness strictly limited to Ra ≤ 0.2 μm and internal roughness within Ra ≤ 0.6 μm, the hypotube ensures smooth internal fluid contrast delivery, rapid balloon inflation/deflation cycles, and seamless guidewire interaction.
Full-Process Turn-key Integration Capabilities
We support medical device OEMs from prototyping to scale by integrating the full manufacturing chain under one roof: Tube drawing, high-speed multi-axis micro laser cutting/slotting, functional chemical/PTFE coating, distal tip modification and core wire laser welding, luer lock/adapter insert-molding, and specialized cleaning, packing, and validation.
