Induction sealing is a non-contact type of sealing used for inner seals in bottle caps..
Portable induction sealing machine is to use electromagnetic induction heating principle is the use of high-frequency current through the inductor coil generates a magnetic field, when the magnetic field lines through the sealing foil material, and instantly generate a large number of small eddy currents, resulting in aluminum foil own high-speed heating, melting compound in aluminum foil on the sol, whereby the sealing paste on the bearing seal material, in order to achieve rapid sealing purposes...
