28kHz Ultrasonic Spot Welder for Nonwoven Fabric Welding
Description Ultrasonic metal welding machine uses the principle of ultrasonic high-frequency vibration and friction to convert the energy of ultrasonic vibration into frictional energy and transfer it to the metal surface to be welded. When the friction generates heat and pressure is applied to it, the metal structural molecules are fully activated. A new type of equipment that forms fusion between molecular layers. Using ultrasonic mechanical vibration, the friction of the processed product produces heat energy to make the plastic reach its own melting point and become a molten state, and then apply a certain pressure to combine. According to the current common situation, it is 20,000 vibrations per second (20KHZ) and vibration per second 15,000 times (15KHZ) two kinds, in addition there are several kinds of special vibration frequency, due to space limitations, only introduce the two more common welding of 15KHZ and 20KHZ. According to its method, it can be divided into direct and conductive welding methods. Direct welding: First make the materials such as wires or bands overlap each other (example: riveting, embedding, etc.), fix the jig on the plastic welding machine, and let the energy converter (HORN) directly generate sonic vibration on it and weld it . Conduction welding: that is, when welding, a distance away from ultrasonic vibration, conduct welding by means of acoustic vibration (example: plastic shell welding, etc.).Main Features spot welding
A. It can weld thermoplastic plastics other than Teflon. B. The splicing time is extremely short, usually ranging from 0.05 seconds to 1 second. C. It can be welded to the joint surface through media such as water and oil. D. The welding effect can reach a practical level. E. It can be directly welded with conduction. F. Material welding energy is different depending on the plastic material, and not all ultrasonic vibration materials, only choose the suitable vibration heat place, and there is no concern about the surface of the product, which is the characteristic of conductive welding. When the harder plastic is welded, the welding effect can be exerted better. G. Ultrasonic welding will not produce the toxicity like chemicals, which is a safe welding process.
