The High Concentricity Mandrel Rod is specifically engineered for cleanroom catheter manufacturing where dimensional stability and surface integrity are paramount. Fabricated from medical-grade 316L stainless steel or optional Nitinol, this mandrel rod offers excellent concentricity, tight tolerances, and burr-free ends, making it ideal for use in liner extrusion, shaft forming, and balloon tubing assembly.
Precision ground and mirror-polished to Ra ≤ 0.1 μm, each mandrel is cleaned using ultrasonic processes and vacuum-sealed in a dust-free environment. This ensures high purity and compatibility with ISO cleanroom production lines, particularly for minimally invasive and interventional catheter systems.
