Jinhua Handheld Electromagnetic Induction Sealing Machine Manufacturer _ Custom Quotation [Wenzhou Kaisha Machinery Co., Ltd.] Principle: Utilizes the eddy current magnetic field generated when electromagnetic energy contacts plastic materials, causing the metal to instantly heat up for practical magnetic thermal conversion purposes. The electromagnetic induction sealing machine, based on this principle, seals bottle containers with aluminum foil pads inside the caps (sealing consumables with attached aluminum foil) through inductive sealing. When the bottle container passes through the magnetic induction zone of the sealing machine, the aluminum foil pad inside the cap is recognized by the induction, causing the aluminum foil attached to the pad to instantly heat up, melting the adhesive layer on the pad to the bottle mouth and becoming one integral unit, achieving an aesthetically pleasing and sturdy product seal.
