Today, Dongguan Yihui Company tells you about the working principle of ultrasonic plastic welding machine:
When the ultrasonic waves act on the thermoplastic plastic contact surface, the ultrasonic energy is transmitted to the weld zone through the upper weldment, because the weld zone is the sound resistance at the interface of the two welds, which generates tens of thousands of times per second. A high-frequency vibration, if this high-frequency vibration reaches a certain amplitude, by doing so will produce a local high temperature. Because the thermal conductivity of the plastic is relatively poor, it can not be dissipated in time, and it is concentrated in the weld zone, so that the contact surface of the two plastics is quickly melted, and then a certain pressure is added to make it merge into one. . When the ultrasonic wave stops, let the pressure continue, with a little pressure holding time, so that it solidifies, so that a strong molecular chain may be formed, so as to achieve a welding purpose, the welding strength can be close to the body of the raw material. strength.
另外超音波振动把电子能给转换成机械能，然后再靠焊头再把能量传达到塑料弓箭只接触面，使得分子和分子间从而产生激烈摩擦生热原理，从而促使产品瞬间熔化并且结合成一体，加工的时速比较快、干净和美观、经济。超声波塑料焊接的好坏主要取决于换能器焊头的一个振幅。
