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