Induction Heating Plastic Catheter Tube With IGBT High Frequency Heating Units
Objective Heat a metal braid in a plastic catheter tube to 250Ā°F (121.1ĀŗC)Ā so that another catheter tube can be bonded to it.
Material 0.05ā (1.27mm)diameter catheter tubes, some with a metalĀ braid, ceramic rod
Temperature 250Ā°F(121.1ĀŗC)
Frequency 306kHz
Equipment ā¢ DW-UHF-4.5kW induction heating system equipped with aĀ remote workhead with one 1.2 Ī¼F capacitor
ā¢ An induction heating coil designed and developedĀ specifically for this application.
Process A single turn helical coil is used to heat the metal braid forĀ plastic reflow. To maintain the correct inside diameter of theĀ tubing. A ceramic rod is inserted through the tubing. Heat isĀ applied for 3.5 seconds to reach 250Ā°F (121.1ĀŗC). The metalĀ braid melts the plastic and creates a bond.
Results/Benefits Induction heating provides:
ā¢ Controlled rapid application of heat
ā¢ Consistent, repeatable results
ā¢ Energy efficient
