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 the   sunscreen for welders . 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 spar...

Working principle In the high-frequency electric field, the dielectric water in the wet leather will be affected by the electric field, causing molecular disturbance and friction and heat between molecules, so that the moisture in the leather will get enough heat and vaporize, and then the steam will be taken away by the air to achieve the purpose of leather drying. Characteristics of rf  dryer (1) The drying speed is fast because the electrical energy into heat, high frequency electric field and leather do not need any intermediary, so in the moment that leather is electrified, heat will produce, to achieve the purpose of rapid drying. (2) Uniform drying, good leather quality if the leather dry to the specific moisture content, will encounter a lot of problems, one of them is the moisture uniformity problem. In the past, most tanneries have dried the leather to a leathery state and then rewetted it. It is said that only in this way can the leather have a ...

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 ...

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 ...

At present, 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 th...
