The Ultra Smooth Stainless Steel Mandrel is engineered for high-speed PTFE tube extrusion and cleanroom-compatible thermoplastic processing. Made from medical-grade 316L stainless steel, this mandrel features an ultra-fine, mirror-polished and electropolished surface with a surface roughness of Ra ≤ 0.1 μm, ensuring low-friction performance and easy separation from extruded liners.
Designed for demanding production environments, it provides tight outer diameter tolerance (±0.005 mm), high axial straightness, and a burr-free finish, making it suitable for continuous extrusion, liner forming, and catheter manufacturing. All mandrels undergo ultrasonic cleaning and are vacuum-sealed for use in ISO-class cleanrooms. OEM customization is fully supported for size, finish, and packaging.
