TPU PU Leather Embossing Radio Frequency Machine

 TPU PU Leather Embossing Radio Frequency Machine

TPU PU Leather Embossing Radio Frequency Machine mainly uses high-voltage rectification self-excited high frequency electron tubes to oscillate to generate an electromagnetic wave current electric field instantly, and uses the processed PVC,TPU, EVA, PET, artificial leather and other thermal plastics and leather materials to generate polarized friction in the internal molecules of the materials in the electromagnetic wave electric field, plus a certain pressure, make the leather and plastic products that need to heat-sealed and welded to achieve embossing effect in concave and convex, which often gratify productive process of decorative embossing, welding reinforcement,tear-off trimming treatment and functional modulation and coding identification 

Product description

TPU PU Leather Embossing Radio Frequency Machine

TPU PU Leather Embossing Radio Frequency Machine obtains priority in flexible products making which is made of polymer material, such as 1st: decorative appearance or embossing on the welded items are possible by engraving or profiling the plates;2nd: by incorporating a cutting edge adjacent to the welding surface, the process can simultaneously weld and cut material, this is often called tear-off weldingbecause the cutting edge compressed the hot plastic sufficiently to allow the excess scrap material to be torn off;3rd: HF welding focuses the heat at the welding target so that the surrounding material does not have to be super-heated and risk burning in order to achieve target temperature at the joint;4th: with HF, heat is generated only the field is energized, this allows for greater control over the amount of energy that the material sees over the entire cycle,when the material can remain under pressure without introducing more heat, it is possible to both instantly heat, weld and cool the material under compression thus increasing the welding strength, even stronger that material matrix;5th: HF generated heat does not radiate off the plates like other heated surface used in welding, this prevents heat degradation of the material abutting the weld

Product uses

TPU PU Leather Embossing Radio Frequency Machine

TPU PU Leather Embossing Radio Frequency Machine solely works with thermoplastic that have dielectric constant,in this process, an electric field is generated near the joint, the direction of which is alternated approximately twenty-seven million time a second, every time the electric field changes, the dipole molecules of the polymer attempt to flip around to realign themselves to the new field orientation, because this movement is impaired by inertia and friction, the molecules dont flip in union, this content relative movement of the molecules results in inter molecular friction which results in heat and subsequently melting that interior heating usually works on flexible products making of sealing, cutting, embossing, forming, coding, imprinting,decoration,edge trimming in commodities made of EVA,PU,TUP,GAG,PET,PETG,APET,PVC,Plastic coated Fabric cloth,artificially leather, likely plastic folding boxes,blister package sealing,athlete shoe vamp and insole, Mobile phone slip cover, badge holder, car mattress,pedal cushion and other automotive interior trim productions
