  What is the difference between automatic high frequency welding machine   and heat-sealing machine heat sealing machine? We briefly introduce the different principles between high frequency voltage processing and hot sealing machine, the different ranges of processed products, as well as the advantages and disadvantages of high frequency processing and hot sealing machine processing, so as to help customers understand the specific differences between high frequency processing and hot sealing machine processing.   Different principle:   High frequency processing principle: as we have said earlier, "automatic high frequency welding machine welding principle" the high frequency magnetic field energy emitted by high frequency tube oscillation, and the conduction effect in the processing of plastic parts, high frequency energy permeability material molecules inside, quickly make plastic molecule polarization of plastic material, material molecules arranged in the same direction

  The leather belt embossing machine  mainly uses a high-frequency, high-voltage rectification self-excited high-frequency tube to oscillate instantaneously to generate electromagnetic wave current electric field. Using the processed leather materials such as PVC, TPU, EVA, PET, etc., the internal molecules of the leather in the electromagnetic wave electric field generate polar friction heat generation. With a certain pressure, the leather that needs to be heat-sealed is welded to seal.   General equipment for leather belt embossing machine: 1. Single-head push-type leather belt embossing machine It mainly uses a high-frequency, high-voltage rectification self-excited high-frequency tube to oscillate instantaneously to generate electromagnetic wave current electric field. Using the processed leather materials such as PVC, TPU, EVA, PET, etc., the internal molecules of the leather in the electromagnetic wave electric field generate polar friction heat generation. With a certain pressur

  The solid state hf welder  is different from the electron-tube high-frequency welding machine. The electron-tube radio frequency welding equipment has output welding transformer. The induction coil is installed on the secondary side of the welding transformer, which is easy to match. Solid state high frequency welding machine in addition to the low working voltage, at the same time slot way capacitance and induction coil, wear on the welding steel pipe resonant directly, because there was no welding, less level of coupling, significantly higher efficiency, and then the production of induction coil, strict and standard, make it match, due to the voltage at the same time, the low induction coil diameter and welding steel pipe diameter (the clearance of v-shaped opening) can be reduced, and it is one of the factors of improving the efficiency of welding. One thing is certain, the induction coil strict and the standard manufacture produces the benefit is far higher than the induction coi

  Impulse refers to the welding current waveform is discontinuous, current size changes.   Generally speaking, pulse type spot welder refers to the sinusoidal alternating current is SCR, divided into sections of current, commonly known as pulse welder. In other words, pulse mode of operation refers to the mode of operating only once every certain interval.   At present, single pulse and double pulse are mostly used in welding.   Conventional pulse gas welding: only one pulse. All the peaks of a monopulse are the same like NNNNN. Pulse gas welding machine is the use of pulse current to achieve droplet transition welding mode, no splash, deep penetration, fine grain, high weld strength, suitable for all-position welding, from 20 a to 500A can achieve stable quality welding, welding performance is far better than the ordinary gas welding machine, is the mainstream direction of welding machine development. Double pulses are equivalent to the superposition of two single pulses with the same

  At present, pvc membrane welding machine  has been widely promoted in a number of plastic welding industry. Various welding defects are inevitable in the process of use. In this article, it mainly analyzes how to solve the problems in debugging or welding.   1.Crush and bruise Pressing injury and abrasion are common problems in the process of pvc membrane welding machine . Sometimes it's not so serious, and it just gets white or marks. When you encounter such problems, the first thing to do is to ensure that the location of the tooling is not out of alignment. First let off the air of the cylinder, press down the welding head, and carefully observe whether the welding head position of the scratch is correct. If the welding head is in the correct position, or if the abrasion or compression occurs on the support (or lower cover), then it is necessary to observe whether there is any interference between the tooling and the product. If it is old tooling, it is suggested to clean the

  High frequency plastic welding machine welding principle:   Working principle of high frequency plastic welding  machine, using powerful high frequency electromagnetic field, make PVC reactive molecules flow or strenuous exercise, again with pressure, to make products up and down movement of the molecular mutual penetration, fusion, achieve the purpose of welding, which due to the intense exercise will generate heat molecules, so after high frequency welding, the product will have a certain temperature.   H f plastic welder  machine work order is: first by the high-frequency electric tube oscillator produces high frequency electromagnetic fields, by the high frequency barrels amplifier, high frequency in barrel again by connecting tube of the copper tape to the electrode plates to welding on the mould, when the product between the upper and lower mold, strong electromagnetic fields make organic molecules flow, through the upper and lower mold, make the mutual penetration of achieve t

  The back fabric cutting after the welding of the automobile suncreen shade is a question that the users of the high frequency welding machine mostly care about. In the traditional process, artificial torn edge and trimming are required after welding sunscreen . As a matter of fact, this work can be done automatically by a high frequency machine.   After cooling the automobile suncreen shade, the design will be finalized, fully automatic high frequency welding will forcing automatically, release pressures around 20 t, the pressure acting on the high strength die will make suncreen shade of PVC fabrics and textile fabrics cut off neatly, the edge of suncreen shade is very smooth, the beautiful degree is much better than the effect of artificial torn edges. Users of the high frequency machine need to be reminded that: when select equipment, remember to choose a high control precision one with a perfect protection function, lest damage the mould if the sparks struck frequently, or to pre
