This operates using Fords capping press to form the foil and transport via cap applicator chute onto advancing bottle then the bottle and foil cap are indexed into the rotary sealer where each cap is pressed down onto the bottle by the dedicated sealing head. Whilst under pressure a precisely measured pulse of induction energy is delivered into the foil in order to make the seal. Fords capping press and rotary turret with 36 Relco P800 induction generators and custom built air cooed induction sealing heads.
Technical Challenges:
Provision of high integrity induction seal whilst also maintaining consistency of seal quality over all 36 sealing heads. Product is hot-filled and as a result there is immediate pressure generated in the head-space of the container. The seal must be able to withstand this pressure build up without failing.
