Zhejiang portable electromagnetic induction sealing machine, how much for one unit? Manufacturer supply [Wenzhou Kaisyu Machinery Co., Ltd.] Principle: Utilizes the eddy current magnetic field generated when electromagnetic and plastic materials come into contact, causing the metal material to instantaneously heat up to achieve practical magnetic thermal conversion. The electromagnetic induction sealing machine, based on this principle, seals bottle containers with an aluminum foil gasket inside the cap (sealing materials attached with aluminum foil) through induction sealing. When the bottle container passes through the magnetic induction area of the sealing machine, the aluminum foil gasket inside the cap is identified by induction, causing the aluminum foil attached to the gasket to instantly heat up and melt the adhesive layer on the gasket to the bottle mouth, achieving an aesthetically pleasing and sturdy product seal.
