How Induction Cap Sealing Works
The food and medical industries require high-speed hermetic sealing between the cap and the container. Induction heating with Ambrell equipment provides the following benefits for cap sealing applications:
- High reliability seals
- Easy integration into production lines
- High process speeds

Induction heating enabled the aluminum to seal to the plastic cap quickly without the cap being damaged. The customer desired a quick rate which would make in-sourcing the process worthwhile, and induction heating exceeded the targeted production rate thanks to its fast heating.

A three-turn two-position helical coil is used to heat the aluminum foil in a tunnel style assembly. Product (containers) passes easily under the induction coil.
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.
