•The inner wall is subjected to ultra-smooth mirror finishing (surface roughness Ra≤0.2μm), greatly reducing frictional resistance when fluid passes through.
Whether used for delivering medicinal fluids, contrast agents, or
blood, it ensures extremely low fluid shear stress and turbulence risk, guaranteeing stable and precise flow rates, meeting the stringent
requirements of high-precision medical instruments for unobstructed
flow paths.
FAQs:
Q: How is the bending angle and radius precision of the tube? Will
there be any defects at the bend?
A: We utilize advanced fiber laser bending forming technology, where the tube is shaped locally with precise heating without
external force. This process grants the bend tube extremely high bending accuracy (angular tolerance within ±0.5°,
radius tolerance ±0.05mm). More importantly, the inner and outer walls at the bend are smooth and flat, free from
dents, wrinkles, or cracks. The geometric form is precisely controllable, ensuring perfect
compatibility during the assembly of minimally invasive medical
devices (e.g., catheters, endoscope channels), eliminating assembly
failures caused by tube deformation.
Q: What is the minimum achievable bending radius? Do you support
customized bending angles?
A: Thanks to our precision laser bending equipment, this small bend
tube can achieve a minimum bending radius of 0.3mm (depending on the outer diameter), meeting the spatial layout requirements of most high-difficulty
minimally invasive medical catheters. Additionally, we fully support custom non-standard bending angles (e.g., 15°, 30°, 45°, 90°, or any irregular angle). Simply
provide us with a drawing or sample, and we will accurately
replicate it for you.
Q: How is the surface finish of the product? What is the
significance for medical applications?
A: The product surface undergoes high-grade electrolytic polishing treatment, with the inner wall roughness Ra value reaching as low as below 0.2μm, and the outer wall achieving a mirror-like finish. The extremely
high surface finish is crucial in medical applications: first, it effectively reduces the retention and coagulation of blood or
medicinal fluids inside the tube, preventing thrombosis or blockage; second, the smooth surface lowers the probability of bacterial adhesion, enhancing the antibacterial performance of the device; finally,
for channels that require repeated passage of guide wires or
instruments, the low friction coefficient can protect the guide wire coating from damage, extending its service life.
