Ultrasonic Welding for Thermoplastic Materials

The connection of plastics is a key part of the wide application of ultrasonic. The plastic can be joined by mechanical fastening, bonding or welding. The fast fastening connection is suitable for all plastics, but it is costly, stress-concentrated, does not form a sealed joint or achieves proper performance. Bonding provides excellent performance and high quality joints, but it is difficult to operate, requires careful joint and surface preparation, and is very slow and not suitable for mass production. The welding is economical, simple, fast and reliable, and can form joints with static strength close to that of the base metal, so it is suitable for mass production and has been increasingly used in the automotive industry. The level of plastic welding technology has become one of the indicators to measure the level of automotive production technology and the level of new material development.

Ultrasonic plastic welding is mainly used for welding thermoplastic materials such as PP and PE and plastic workpieces with large and complex weld area.
