Bildung der Teflonspitze des Katheters

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 (315.6-371ºC)

Frequency: 376 kHz

Equipment:

• Ambrell 3 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 (371.1ºC) 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.

Benefits:

• Precise, repeatable application of heat
• Non-contact heating
• Faster cycle times
