在本文开始时首先对连接与焊接二个概念加以解释。这里所涉及的有关塑料超声波焊接仅是诸多塑料连接方法中的一种。除此之外,塑料还可进行铆接、翻边联接和在塑料中植入金属件等。 在开始讨论塑料超声波焊接方法应用的可能性,以及所涉及的材料和设备之前,我们先来暂短地回顾一下历史,超声波技术是何时开始在实践中得到应用的。 At the beginning of this article, we first explain the two concepts of connection and welding. The plastic ultrasonic welding involved here is just one of many plastic joining methods. In addition, the plastic can also be riveted, flanged joints and plastic parts such as metal. Before we start discussing the possibilities of using plastic ultrasonic welding methods, and the materials and equipment involved, let’s briefly review the history of when ultrasonic technology was applied in practice.
