Semi Automatic Induction Cap Sealing Machine
The process of Induction Cap Sealing is based on the principle that a conductive material i.e. Al Foil heats up on exposure to high frequency magnetic field generated by an Induction Unit. This is a non contact process without direct heat transfer. Due to this, the sealable closure liner can be placed in the cap by the manufacturer. The Wad consists of a board packing material, a wax layer, Aluminum foil and a sealable film. The screw cap combination passes through the induction unit after closure of the container. When the container is under the induction head, heat is developed into the Aluminum layer. The wax layer starts to melt and penetrates into the board layer. The Sealing layer also melts & forms a tight seal against the lip of container. The necessary pressure is provided by the liner/screw cap combination. On opening the container, the board remains inside the cap and serves as a seal on further use, whereas the aluminium foil is permanently sealed on the rim of the mouth of container.
Semi Automatic Table Top: 4 To 5 Containers per Minute
Portable Induction Sealing System for very small production units. It can seal from 10mm up to 53mm and can give 4 to 5 containers per minute. This system does not require water cooling as it is equipped with an inbuilt timer. There are separate Induction Head available for various diameters ranges.
