超声波塑胶焊接原理：
Principle of Ultrasonic Plastic Welding:
      超声波塑胶焊接有发生器产生20KHZ（15KHZ或40KHZ）的高压、高频信号、通过换能系统，把信号转换为高频机械震动，加压与塑焊制品工件上，通过工件表面及内在分子间的摩擦而使传到接口处的稳定升高，当稳定到此工件本身的熔点时，使工件接口迅速熔化，继而填充于接口间的空隙，当震动停止，工件同时在一定的压力下冷却定形，达到完美的焊接。
    The generator produces 20KHZ(15KHZ or 40KHZ)high-volage and high-frequency signal and translates it via a transducer into high-frequency mechanical vibration, which is exerted to the articles to be plastic-welded. The friction on the surface of the articles and the molecules inside leads the temperature at the interface to rise to their melting point, so that the interface of the articles melts quickly and the void between their interfaces is filled. When vibration stops, the articles get cooled and shaped at some pressure, which can make the welding perfect.
      超声波塑胶焊接机在焊接塑料制品时，既不要添加任何粘接剂、填料或溶剂，也不消耗大量热源，具体操作简便、焊接速度快、焊接强度高、生产效率高等优点。因此超声波焊接技术越来越广泛地获得应用。
    While ultrasonic plastic welder is welding plastic products, it neither needs to add any adhesive, nor consumes a large deal of heat. This welder enjoys easy and quick operation, high strength and productivity. Therefore, the technology of ultrasonic welding is more and more widely applied in practice.
