Ambrell sold a 4.2-kW, 150- to 400-kHz induction heating system to a medical-industry company for a catheter tipping application. The process involves heating an aluminum catheter tipping die to 500°F (260°C) and then pressing the polyurethane tube into the mold. A wire is used during the process to prevent the collapsing of the tube. Other medical applications that Ambrell has experience with include nanoparticle heating, soldering and bonding of medical tools, and hardening of medical blades.
