Ultrasonic welding has been widely used in the sector of plastics and synthetic materials. Ultrasonic welders replace the traditional jointing methods with the use of solvents. Ultrasonic welders are formed by a generator, a converter, the booster and the sonotrode.
Sonic, which has long been on the market of ultrasonic welders, developed a range of "standard" systems to be used within the different product sectors that require this type of welding. For its own ultrasonic welding systems, Sonic manufactures a wide range of sonotrodes and boosters that must be used in the different types of welding.
The use of the ultrasonic technology to weld plastics allows achieving varied results according to the different applications.

超声波焊接在塑料材料及合成材料领域的应用日益广泛。超声波焊接设备正在取代利用溶剂焊接的传统模式。超声波焊接设备由发生器，换能器，变幅器及焊接模具构成。
Sonic公司立足于超声波焊接机市场业已多年，开发出了一系列“标准”系统，适用于各种对该焊接模式有需求的商品领域。 Sonic公司同时为自产的超声波焊接系统生产全套焊接模具和变幅器，适用于不同类型的焊接。
超声波技术在塑料材料焊接方面的使用会根据不同的应用方式得到不同的结果。
