Induction Heating Molding Catheter Tip With IGBT High Frequency Heating Units
Objective Heat a water-cooled steel mandrel to 700Ā°F (371ĀŗC) to form aĀ high quality Teflon catheter tip.
Material Teflon catheter tubing, mandrel assembly
Temperature 600-700Ā°F (315-371ĀŗC)
Frequency 376 kHz
Equipment ā¢ DW-UHF-6Ā kW induction heating system, equipped with aĀ remote workhead containing one 0.66Ī¼F capacitor.
ā¢ An induction heating coil designed and developedĀ specifically for this application.
Process A two turn coil is used to heat the steel mandrel to 660ĀŗFĀ (371ĀŗC) in 2.7 seconds. To form the catheter tip, RF power isĀ applied while the catheter is held over the mandrel. The tubingĀ is then pushed on to the mandrel to form a consistent, even tip.
Results/Benefits Induction heating provides:
ā¢ Precise, repeatable application of heat
ā¢ Non-contact heating
ā¢ Faster cycle times
