Catheter Tipping With Induction

How is induction heating used in catheter tipping?

Ambrell has offered catheter tipping solutions for the medical industry since 1986. Our expertise in developing these applications is applied by medical instrument manufacturers worldwide.

Induction generates an electromagnetic field in a work coil that induces currents in the conductive material of a workpiece placed within or near the coil. Friction from these currents elevates the temperature of the workpiece to be heated.

Induction catheter tipping Benefits

Meets tight production tolerances with precise localized heat to small areas creating pinpoint accuracy
Increases production rates with faster heating cycles
Reduces defect rates with repeatable, reliable heat
Eliminates variability from operator-to-operator, shift-to-shift
Maintains metallurgical characteristics of the individual metals

Heat a metal braid in a plastic catheter tube to 250°F (121.1ºC) so that another catheter tube can be bonded to it.

Is Catheter Tipping with Induction the Least Expensive Process?

Depending on the specific medical requirements and frequency of use induction might not be the most cost effective way to produce catheters. The initial investment and training required could make other heating technologies more financial viable when considering lower output volumes

Will Catheter Tipping with Induction Reduce Production Costs?

When high production capacity is required induction heating will reduce down time / setup time / increased speed and higher product quality with less wastage.
