Heating Steel Tubes with Induction for Adhesive Bonding

A manufacturer in the medical industry was seeking to heat steel tubes for an adhesive bonding application. The parts were stainless steel tubes on plastic tubes. Initial testing confirmed that an EASYHEATTM 1.2 kW, 150-400 kHz induction heating system equipped with a remote workhead was the right system for this induction adhesive bonding application.

For testing, temperature indicating paint was applied to the part, which melts when the part reaches the targeted temperature. Testing showed that it took 5.0 seconds to heat the sample to temperature. After the part cooled to room temperature, it was compared to client-provided finished assemblies to confirm that the plastic was sufficiently bonded to the inside of the steel tube. Five assemblies were heated by THE LAB at Ambrell and the application was successfully proven out.


Repeatability was critical for the client's application, and induction from Ambrell is highly repeatable. The speed and precision of induction heating was also important to the client, which THE LAB proved induction could deliver. The EASYHEAT's modest size also fits nicely into the client's manufacturing process, and the EASYHEAT's reputation plus the fact it's built at Ambrell's Scottsville, NY USA headquarters were also deciding factors.
