Successful sealing on both capless and non-screw-cap containers such as snap on caps is now possible with a pressure sealer incorporating an Enercon Super Seal™ unit.
Typically, pressure belt sealing is used to replace conduction sealing or to reduce the dwell-time needed in conduction sealing.
Conduction sealing is a slow and expensive process requiring high maintenance. Adding a pressure Induction Sealer to the line increases production speed and reduces energy costs.
Seals are either placed onto the capless containers or reside in the cap as inserted by the cap manufacturer.
The capped container is then guided through the induction heating tunnel, where downward pressure is applied to the clip-on cap or foil by a non-metallic recirculating belt.
This unique design automatically takes account of component variations and tolerances, such as bottle height variation, product overfill, line speed variation and bottle centres. The top pressure is maintained following initial release from the induction heating field.
