High frequency wave is high frequency wave. High frequency wave and ultrasonic wave are two different concepts. High-frequency wave refers to electromagnetic wave with frequency greater than 100Khz, and ultrasonic wave refers to sound wave with frequency greater than 20 kHz. The welding principle of high frequency wave is also different from that of ultrasonic wave. High-frequency wave uses high-frequency electromagnetic field to make molecules in materials collide with each other violently to produce high temperature to achieve the purpose of welding and welding, while ultrasonic wave uses the principle of friction to generate a lot of heat to achieve the purpose of welding and welding. High frequency is widely used, so there are high frequency plastic welding machine, high frequency skin plastic fusing machine, high frequency folding box creasing machine, high frequency metal heating machine and so on.
High frequency plastic welding machine (also known as high frequency machine, high frequency machine) is the first choice for plastic packaging. It uses high-frequency electric field to make the molecules inside the plastic oscillate to generate heat energy, so as to fuse various products. Mainly used for: welding, fusing and bronzing of various PVC-based plastics. Blister packaging (including upper and lower double blister heat sealing trimming, blister and cardboard heat sealing trimming, etc.). ), automobile interior parts, cushions, trademarks, stationery, stickers, plastic covers, blowing toys, footwear products, rain sails, umbrellas, raincoats, purses, famous brands, waterbeds, sun visors, door panels, heat sealing processing of various packaging bags, portable soft bags, and patterns of various concave-convex switches. You can also install a simple device for bronzing.
