一前言 随着超声塑料焊接这一新工艺的不断发展,对不同类型超声波焊接设备的需要越来越突出,输出功率在1千瓦以下的超声波焊接机已不能满足用户的要求,特别是对较大塑料件和可焊性比较差的材料焊接就需要提供更大功率的超声波焊接机,为此我厂在系列产品的基础上又研制成功了功 A foreword With the continuous development of ultrasonic plastic welding new technology, the need for different types of ultrasonic welding equipment is more and more prominent, the output power of 1 kilowatts below the ultrasonic welding machine has been unable to meet the user’s requirements, especially for larger Plastic parts and solderability of relatively poor welding materials need to provide more power ultrasonic welding machine, for which I plant in the series of products based on the successful development of the power
