Medtech companies have demanded increasingly complex geometries in medical tubing. Here’s a rundown of five manufacturing processes that could help them get there.
Dan Sanchez, Trelleborg Healthcare & MedicalHere are several tubing processes that may be of interest to medical device designers:
Geometric transition extrusion
With geometric transition extrusion, tool components can be moved during the extrusion process to change tubing geometry. For example, a tube can transition from single to multiple lumens or split from a multi-lumen tube into two or three single lumen tubes. Extruding different geometries in one process eliminates assembled joints that may be weak or create internal misalignments where fluids can become turbulent or stagnate.
