Ultrasonics
This process works through the translation of AC current into mechan using piezo-electric ceramics. The vibrations are then passed throug the joint at which point they cause stress and strain in the contact are two parts which leads to localized heating and melting of the polyme welding typically has weld times from one-tenth to two seconds and welding equipment can handle parts from approximately one-eighth at high frequencies up to twelve inches square at low frequencies.  ultrasonic plastic welding generator. ultrasonic plastic case welding machine
