-
Non-contact processing: Removes mechanical stress and tool wear
Laser cutting’s non-contact processing eliminates tool wear and workpiece deformation, which supports mass production of high-precision parts. The process provides a rapid, repeatable and cost-effective alternative to traditional machining or EDM methods.
Laser Cutting Tubes and Hypotubes in Medical Devices
Hypotube cutting represents one of the most demanding applications in medical laser processing because these small-diameter tubes require thin walls without distortion. These tubes support catheters, guidewires and drug delivery systems, where reliability and flexibility matter.
Modern systems process hypotubes with thin wall thicknesses and small outer diameters while maintaining dimensional accuracy. Laser systems provide micron-scale precision for complex geometries, slits and angled tips in metal hypotubes. This capability enables features such as flex zones, steerable shafts and variable stiffness regions that conventional methods cannot match.
Companies that require precision hypotube cutting with integrated finishing and assembly can discuss specific requirements with Fabcon’s engineering team.
