Induction sealer — Machine Operation & Checks

Capped bottles pass under the blue sealing head. The head creates an electromagnetic field that heats the foil liner in the cap and bonds it to the bottle rim. Three settings control the seal: the sealing power (voltage), the head height and the conveyor speed.

1. 1Check the cooling water level: open the rear door, check the level inside the tank and top up to the mark only if needed (I-06). Switch on the sealer.
2. 2Set the sealing power for the bottle (reference 75 V for 120 cc) and the conveyor speed.
3. 3Set the head height with the handwheel to about 3 mm (1/8 in) above the cap, or as the sealer manufacturer specifies, and lock the knobs.
4. 4Run 2–3 test bottles and check the seals (Section 6.11): full bond, no burns, no wrinkles.
5. 5Seal weak: lower the head slightly, or increase power, or slow the conveyor, one change at a time. Foil burnt: raise the head, or reduce power, or speed up the conveyor.
6. 6Re-test 2–3 bottles after every change. Do not fix the settings until the test bottles pass.
7. 7Record the final power, head height and conveyor speed.
