What is the difference between the principle of high frequency machine and the principle of ultrasonic?

Generally speaking, if you have an understanding of high frequency , you will hear ultrasound . What is the difference between the principle of high frequency and the principle of ultrasound? Below I will give you an analysis.

   The high-frequency principle uses high-frequency waves higher than 100KHZ to work. It generates high-frequency electromagnetic fields (also called high-frequency electromagnetic fields) through a high-frequency oscillation tube (also known as an electronic tube) self-excited oscillator, and ultrasonic waves are generally used at 20KHZ or 15KHZ The frequency wave to work, it depends on the vibration of the head friction. Because their bands are different, the products they press are also different. For example, the high frequency plastic welding machine is mainly used for soft plastic materials containing 10% PVC. And so on, but the ultrasonic machine is mainly used for the welding of hard plastics, the hard plastics of the welded products are injection molded, and the welding is ABS.

There are several names for  high-frequency plastic welding machines in China. The mainland is usually called high-frequency machines and high-frequency heat-sealing machines , Hong Kong compatriots are usually called voltage machines, and Taiwan compatriots are called high-frequency machines. In fact, they are all kinds of machines, but they are called differently. The working cycle frequency of the machine is between 27.12 and 40.68MHZ, so it is called a high-frequency machine or a high-frequency machine. The high-frequency machine is widely used in the field of plastic welding. It can weld or fuse PVC, PET, TPU, PE and other polymer environmentally friendly materials. Various products, such as blister packaging and sealing, single-sided blister and cardboard heat sealing, luggage and shoes and other leather embossing and embossing patterns and embossing patterns, stationery boxes, PVC documents, rain Sails, umbrellas, raincoats, water beds, inflatable toys, soft film ceilings, PVC tents, various packaging bags, ice coolers, hot water bottles, portable PVC soft bags, hemodialysis bags, car sun visors, door panels, interior parts, Foot pads, high-end mobile phone leather goods, motorcycle seat cushions, high-frequency vacuum toilet seat cushions, underwear TPU magnetic bags, medical supplies, etc., so high-frequency machinery is specially developed for the above products and related similar products or industries.
