Braided Composite Catheter
Our braid-reinforced tubing is expertly crafted through advanced co-extrusion or reflow methodologies, integrating robust metal or fiber braided structures between dual layers of premium material. This state-of-the-art design remarkably boosts the tubing's burst pressure resistance, column strength, and torque transmission capabilities. The braiding angle, coverage, and the dimensions, shape, and strength of the reinforcing materials are meticulously optimized to ensure the tubes deliver outstanding performance. We take pride in our ability to produce mesh-braided tubes with unparalleled precision and superior mechanical properties, customized to fulfill your specific needs.
Coiled Reinforced Catheter
Our Coil Reinforced Tubing is skillfully engineered by embedding durable spring coils between dual material layers through sophisticated co-extrusion or reflow techniques. This results in a composite tubing that offers enhanced pressure resistance, exceptional fold resistance, and superior torsional control. We are unwavering in our dedication to meet our clients' distinct needs by tailor-making product development and production. The coil reinforced tubing is distinguished by its exceptional smoothness, exceptional compatibility, and reliable support.
