Qingdao Tianrun high frequency (Figure), Qingdao High frequency plastic welding machines, high frequency plastic welding machine provided by Run High Frequency Electric Co., Ltd. Qingdao days. High Frequency Electric Co., Ltd. Qingdao Tianrun (www.gaozhoubo.com.cn) is a professional engaged in "high-frequency induction heating equipment, ultrasonic plastic welding machine, welding machine, laser cutting machine" of the company. Since its inception, we adhere to the "honesty, sound management" approach, the courage to participate in healthy competition in the market, so that the "days Run, Run Qingdao days, days Run High Frequency" brand has a good reputation. We adhere to the "service first, customers first" principle, so that high-frequency Qingdao Tianrun won the trust of customers congregation in the packaging-related equipment, and establish a good corporate image. Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! 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 whole object of high frequency plastic welding machine accessories, opposite the object being heated with a heating current internal The direction, there will be corresponding large eddy currents. Because of the heated object memory in the resistance, it will generate a lot of Joule heat, so 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 the magnetic field acting on the metal object in; the use of eddy current effect, generates a magnetic field proportional to the intensity of the induced current in the metal object, the current flow in the metal object when the Shandong High Frequency plastic heat sealing machine, will aid internal resistance values ??inherent in the principle of thermal effect by the current generation of heat, this heat is generated directly within the body, 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 induction heating main control panel, the main use as a PWM pulse forming SG3525A, the output pulse frequency range 20KHZ-60KHZ, pulse interval of 180 degrees to each other, the dead time can be self-adjusting. Applicable to full-bridge inverter IGBT series resonant induction heating installations chopper voltage regulation power. Power range: 15KW-120KW high frequency plastic heat sealing machine theory, the less control panel wiring, control concentrated high frequency plastic welding machine, without commissioning, operating supply voltage for the three-way exchange of dual 18V / 1A and four 22V / 0.5A power supply provide power for full-bridge inverter IGBT driver circuit. Overcurrent, overvoltage, dry, high-frequency, low frequency, a variety of status indicators, and provides an interface hall switch protection, this board can be used with the chopping board and driver board assembly IGBT high frequency induction heating device.
