  There are many factors affecting the effective power output of high frequency welder. Therefore, the major high frequency welding machine manufacturers  should pay attention in the production of high frequency welder. The effective output power of high-frequency welding machine is mainly affected by the following aspects:   1. Welding V Angle, the most economic and efficient Angle is between 2-3 °. In addition to electromagnetic induction heating, there are two important effects, namely skin effect and proximity effect of main principle of high frequency welding. The smaller the welding V Angle is, the closer the proximity effect will be, so that the effective output power of the welding machine can be used more effectively.   2. The shape of the two welded surfaces of the pipe should be parallel to each other. This will make the welding more efficient and the molecular diffusion between the two surfaces more uniform.   3. Welding temperature. Welding temperature plays a decisive rol

  Features of inflatable welding machine: 1. The operation of inflatable welding machine Inflatable welding machine has two push dials, two work bits. The operator only needs to put the products in it, push the push plate to trigger the micro switch, and the molds go down automatically, heat up, and go up. The whole process is simple and safe with high frequency. Staff can use the machine without special training.   2. Adjustment of output force of inflatable welding machine It adopts special low loss coaxial oscillator, which can adjust the output force at any time due to the size of the mold and the thickness of the glue. When you operate the inflatable welding machine, it will not cause interference with telecommunication with it. The adjustment of output can also be combined with the time system to maximize output. The heat sealing machine can weld the product in the shortest time and increase the production.   3. Protection device of inflatable welding machine A: current limiting

  Membrane hf welding machine  is the electromechanical system used to realize high frequency welding. The membrane welding machine is composed of high frequency welding machine  and tube welding machine. Membrane welding machine  is generally composed of two parts: high frequency generator and feeding device. Its role is to generate high frequency current and control it; the forming machine consists of an extruding roller stand. Its function is to squeeze the part that is melted by the high-frequency current.   1. High-frequency generator: in the past, the high frequency generator used on the welded pipe unit was three-loop and it's basically been improved to a single loop later. There are many methods to adjust the output power of high frequency oscillator, such as autotransformer, reactance method, thyristor method and so on.   2. Feeding device: it is used to transmit high frequency current to the tube, including electrode contacts, induction coil and impedance. In general, in

  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 hf pvc welder . 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 tooling with a

  1.The basic principle of pvc door welding machine : This machine mainly adopts operating principle of high-frequency machine and radio   frequency. It makes use of the high - voltage transformer rectifier self - excitation high frequency tube oscillation moment to produce the high frequency electromagnetic wave current electric field. It makes use of processed materials PVC, TPU, EVA, PET in the field of high frequency electromagnetic wave, the internal molecules of plastic and plastic materials to produce polar heat conduction. Achieve welding sealing role of the plastics and plastic products needed for thermal welding by increasing some pressure.   2. Basic structure of pvc door welding machine: 1) the machine is mainly operated by double-head pedal pneumatic operation. The operation position is divided into the left and right sides of the handpiece. The operation table is designed with aluminum material, so that the electrical conductivity is more stable. The method of operation:

  fter RF welder for sale by enterprises, there may be some breakdowns. Therefore, after RF welder for sale, enterprises need to provide after-sales service, including finding out the cause of failure, treatment, maintenance and so on. Liaoning Yufei High-Frequency Equipment Co., Ltd . is a professional RF welder manufacturing enterprise, devoted to the design, production, rf welder for sale  and it provides thoughtful after-sales maintenance services?   Common failures of welder mainly include the following aspects: 1. The welder has no welding current output The cause of the problem: no voltage input at the hf welding equipment  input end; The internal wiring is off or broken; The inner coil is burnt out.   Treatment: check whether the switch, wire, fuse wire and connection parts from the distribution box to the input end of the welding machine are intact. Check whether the wiring of switches and coils in the welder is intact. Check whether the primary windings and secondary windings

  Why is matching at all power levels important? As we all know, in the process of high-frequency welding, the production line is subject to various load changes, and the quality of the welding seam changes with the change of load. What we need is a consistent output, which is necessary for high-quality welds. If you do not pay attention to it, it will influence the high-frequency PVC welding machine for sale .   In the actual production process, the welding speed (speed), welding frequency, welding power, opening Angle size, impeder position, impeder working condition, magnetic flux size, steel strip thickness, welded pipe diameter, cooling water temperature, even deburring and the habits of operators of different teams will affect the load matching. Therefore, the continuous perfect match is the premise to ensure consistent welding quality. Any of the above changes in the pipe production process will cause changes in the load of the welder, which is why the high-frequency welder with

Welding method 1. PVC welding method: Ultrasonic vibration is transmitted to the weldment with the welding head. Since the sound resistance of the two weldments is large, local high temperature is generated, and the weldment interface is melted. Under certain pressure, the two weldments achieve an aesthetic, fast and strong welding effect.   2. PVC welding embedding method: Nuts or other metals are inserted into plastic parts. First, the ultrasonic wave is transmitted to the metal, and after high-speed vibration, the metal object is directly buried in the molded plastic, and the plastic is melted at the same time. After it is cured, it is buried.   3. PVC welding riveting method: If you want to join metal and plastic or two plastics with different properties, you can use the ultrasonic riveting method to make the welding parts not easy to be brittle, beautiful and strong.   4. PVC welding spot welding method: The small welding head is used to weld two large plastic products by spot wel
