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