Principle Of High Frequency Machine

    High frequency principle refers to the high frequency electromagnetic field (also known as high frequency electromagnetic field) generated by high frequency oscillating tube (also known as electron tube) self-excitation oscillator, high frequency and high frequency welding machine, high frequency plastic welding machine, high frequency heat sealing machine is the same machine. Many years ago, the machines in Mainland China were originated from Hong Kong and Taiwan. Hong Kong people called them high-frequency welding machines, while Taiwanese called them high-frequency welding machines. So it evolved into this kind of machine called a lot of times, and it is processed. The object is pressed between the upper and lower electrodes with high-frequency electromagnetic field, and its internal molecules are excited and move at high speed to oscillate with each other to generate heat and melt. Under the combination of the pressure of the machine and the mold, the plastic can be welded, imprinted, laminated, etc. , Make the pressed things beautiful and generous.

    The high-frequency principle also uses a kind of thermal energy, but it is different from the ordinary heating machine. The ordinary heating machine relies on the upper die or the lower die to slowly infiltrate heat and weld together, while the high-frequency welding relies on instantaneous thermal energy. Together, if the product is pressed by ordinary heating, it will cause the deformation of the pressed plastic product, and the high-frequency wave is cooled by instant heating and instantaneous power failure, so the pressed product is more beautiful than ordinary heating machines.

    The frequency generated by the oscillator of the high-frequency machine is 27.12MHZ or 40.68MHZ. This band complies with the international industrial band standard. With special electronic circuits for various control devices, this safe band can avoid improper operation, and can weld products instantly and increase product output. High-frequency machine refers to electromagnetic waves with a frequency higher than 100Khz. Because high-frequency waves have electromagnetic waves greater than 100Khz, sometimes if the operation is improper or the mold is not working, the material will cause occasional sparks. There are high-voltage electricity in the high-frequency machine. Non-professionals It is best not to open the case to check the machine. If you have to check the machine in a hurry, please turn off the power switch to avoid high-voltage electric shock. High-frequency transformers generally have high voltages of thousands of watts, so you need to pay attention. Safety, do not touch the high-voltage transformer during work, otherwise it will cause unnecessary personal safety first.

    There are two main types of high-frequency plastic welding machines used in industry. One is called high-frequency plastic welding machine (that is, this type produced by our company). Shell welding, PVC plastic blister welding, battery blister paper card packaging, medical industry urine bags, infusion bag cloth, automotive interior industry, inflatable toy industry, plastic packaging industry, automobile trademarks, embossing, clothing embossing Wait, the other is called high-frequency heating machine (mainly used for welding of metal materials), so customers who need to buy high-frequency welding machine should tell us according to their products, and our company will recommend the most suitable for you according to your products. machine.

    Zhenjia high-frequency welding machine has more than ten years of experience in high-frequency plastic welding machines. From procurement to production to after-sales, we have a professional team. If you have any questions about the principle of high-frequency, please consult our company.
