In the latest application video from THE LAB at Ambrell, a cap sealing application is tested. Cap sealing with induction is a non-contact heating method that welds the foil laminate to the lip of the container, commonly plastic or glass. In this case, the client had been using a cap sealing device that wasn't delivering enough power for this large plastic container, so the heating wasn't fast enough to meet their throughput requirements. Consequently, they turned to THE LAB for a proper induction solution.

A company from the food industry came to THE LAB at Ambrell to see if induction might be a fit for their cap sealing (bonding) application. The application involved heating aluminum foil inside a plastic bottle. Induction's speed and repeatability were of particular interest to the client. Induction is an especially good fit for high volume production applications like this cap sealing application, which we'll discuss again later in this post. 

A client in the beverage industry needed to heat aluminum caps for a cap sealing application. The application involved reusable caps on aluminum cans. THE LAB at Ambrell determined that an EKOHEAT^® 45 kW, 50-150 kHz induction heating system equipped with a custom coil and remote workhead would work well for this heating application. 

The objective of this application was to heat an aluminum seal for cap sealing to a plastic container. The client had been using another method for cap sealing which was more time and labor intensive. The client turned to THE LAB at Ambrell to see if induction heating with an Ambrell system could allow them to reduce their cap sealing process time to just seconds.
