Induction Heating Plastic Catheter Tube

Induction Heating Plastic Catheter Tube With IGBT High Frequency Heating Units Objective Heat a metal braid in a plastic catheter tube to 250°F (121.1ºC) so that another catheter tube can be bonded to it. Material 0.05” (1.27mm)diameter catheter tubes, some with a metal braid, ceramic rod Temperature 250°F(121.1ºC) Frequency 306kHz Equipment • DW-UHF-4.5kW induction heating system equipped with a remote workhead with one 1.2 μF capacitor • An induction heating coil designed and developed specifically for this application. Process A single turn helical coil is used to heat the metal braid for plastic reflow. To maintain the correct inside diameter of the tubing. A ceramic rod is inserted through the tubing. Heat is applied for 3.5 seconds to reach 250°F (121.1ºC). The metal braid melts the plastic and creates a bond. Results/Benefits Induction heating provides: • Controlled rapid application of heat • Consistent, repeatable results • Energy efficient
