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.
THE LAB designed a channel coil that would work well as large containers passed underneath it. It was designed so the heat from the coil would heat the seal and the pressure from the cap would tighten it and seal it to the bottle. One second was the time the container had to pass underneath the coil and THE LAB's testing proved that would be sufficient to perform this cap sealing application. Now, take a look at the video:
