The welding characteristics of 27, 40 and 67 kHz ultrasonic plastic welding systems that are driven at only the fundamental-resonance frequency vibration were compared, and also those of the welding systems that were driven at the fundamental and several higher resonance frequencies simultaneously were studied. At high frequency, welding characteristics can be improved due to the larger vibration loss of plastic materials. For welding of rather thin or small specimens, as the fundamental frequency of these welding systems is higher and the numbers of driven higher frequencies are driven simultaneously, larger welded area and weld strength were obtained.
比较了仅在基频共振频率振动下驱动的27、40和67kHz超声塑料焊接系统的焊接特性,还研究了同时在基频和几个更高共振频率下驱动的焊接系统的焊接特性。在高频下,由于塑料材料的振动损耗较大,焊接特性可以得到改善。对于相当薄或小的试样焊接,由于这些焊接系统的基频较高且同时驱动的更高频率数量较多,因此获得了更大的焊接面积和焊接强度。
