Induction Heating Molding Catheter Tip

Induction Heating Molding Catheter Tip With IGBT High Frequency Heating Units

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