Electromagnetic Induction Sealing Machine Price - Manufacturer - Wholesale - Sales - Contact Information [Wenzhou Kaisyu Machinery Co., Ltd.] Portable Electromagnetic Induction Sealing Machine for Large Diameter Honey, Chili Sauce Plastic Bottles, Glass Water Bottles, Medicine Bottles, Egg Yolk Cake Oils, Urea Tubs, Aluminum Foil Laminates, and Sealing Sheets. Principle: Utilizes the eddy current magnetic field generated when electromagnetic energy contacts plastic material, causing the metal to instantaneously heat up for magnetic thermal conversion to practical use. The electromagnetic induction sealing machine, based on this principle, seals containers with caps containing aluminum foil inserts (sealing materials with attached aluminum foil) through induction sealing. As the container passes through the magnetic induction zone of the sealing machine, the aluminum foil insert inside the cap is sensed, causing the foil to instantly heat up and melt the adhesive layer on the insert to the bottle mouth, achieving a beautiful and secure seal.
