1, high-frequency and high-frequency current flow machine is made of circular or heating coil (usually with copper production) other shapes. Coil which produces instantaneous changes in the magnetic polarity of the beam, the metal is heated object is placed inside the coil, the magnetic flux will be heated through the entire object, the object being heated inside the heating current in the opposite direction, there will corresponding large eddy currents. Because of the heated object memory in the resistance, it will generate a lot of Joule heat frequency heat sealing equipment, so that the rapid rise in their body temperature. All metallic materials to achieve the purpose of heating. 2, in the high frequency machine by a unique set of electronic circuits, external power input comes from 50Hz low frequency alternating current into alternating current of high frequency above 20000Hz; after a high-frequency current to the coil, using electromagnetic induction principle is converted into a high-frequency magnetic field and a magnetic field acting on the metal object is; eddy current effect, generates a magnetic field proportional to the intensity of the induced current in the metal objects, the current flowing in the metal objects, it will by means of the inherent internal resistance value thermal effect generated by the current principles of heat, this heat is generated directly within the object frequency heat sealing equipment features, so this heating method, fast and efficient. If required, any metal material which can be melted in an instant. Moreover, it is the heating rate and temperature controlled. High frequency machine described in the mainland of China's high frequency product called high-frequency, as the name suggests is to achieve an ultra-frequency device, usually international standards in 40.68MHz, 27.12MHZ, 13.56MHz different devices collectively referred to as high frequency frequency machine. Mainly used in modern industrial welding equipment needed in the market needs we can often see: "Metal frequency machine, plastic high frequency machine, bentwood high frequency machine", their role is mainly used for different materials not the way to be welded. High frequency heat sealing machine is mainly used for: plastic packaging (including heat trimming down double blister, blister and cardboard heat trimming) high-frequency welding equipment, automotive interior parts, trademarks, stationery, raincoats, inflatable toys plastic cover, cool liquid cushion, footwear, cushions, a variety of bags, hand bags and other soft heat of processing, uneven patterns of various shapes, letters, text repression. Fitted with a simple device can also be bronzing process.
