What is ultrasonic plastic welding

　Ultrasonic plastic welding is a solid-phase welding method in which the connection between the weldments is achieved by the high-frequency elastic vibration of the acoustic system and the clamping of static pressure between the workpieces. Due to factors such as the injection molding process, a considerable number of plastic products with complicated shapes cannot be injection molded at one time, which requires bonding, and the plastic bonding and heat sealing processes that have been used for many years are quite backward, not only inefficient, but also in adhesives. There is a certain degree of toxicity, causing problems such as environmental pollution and labor protection. The traditional process can not be applied to the development needs of the modern plastics industry, so a novel plastic processing technology — ultrasonic plastic welding stands out for its high efficiency, high quality, beautiful, energy saving and other advantages. 
　Ultrasonic plastic welding machine, when welding plastic products, does not add any adhesive, filler or solvent, does not consume a large number of heat sources, has the advantages of simple operation, fast welding speed, high welding strength and high production efficiency. Therefore, with the wide application of thermoplastics and their composite materials, ultrasonic plastic welding has become more and more widely used.
