How Induction Catheter Tipping Works

Catheter tipping (also known as end forming) involves molding a rounded tip on the end of a thermoplastic tube. With catheter tipping, induction heating raises the temperature of the conductive mold. This is done without using a flame or making direct contact with the mold. The tip of the catheter is then formed by inserting the plastic tubing into the heated die or mold to form the rounded edges. The rounded end of the catheter tube allows it to be safely inserted into a human with minimal body tissue trauma.

This application requires relatively lower power, often in the range of 1 to 3 kW, depending on the parts and application requirements. Ambrell has offered catheter tipping solutions for the medical industry since 1986. Our engineering expertise in developing catheter tipping applications has been applied by manufacturers of medical instruments worldwide.

About Induction Heating

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. The material may be a metal such as brass, aluminum, copper or steel or it can be a semiconductor such as silicon carbide,carbon or graphite. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.
