Assembly Ultrasonic Welding Of Thermoplastics

Ultrasonic welding is the process by which two pieces of plastic are joined together through the use of high-frequency acoustic vibrations. For the process one half of the component is placed on a fixed anvil and the second half is placed on top. An extension, connected to the transducer on the welding machine, called a “horn” is then lowered down on top of the two components. Once the horn is in place a very rapid low-amplitude acoustic vibration is applied to the moulding in a small welding zone. This vibration causes the acoustic energy to be converted into heat energy and the two components are welded together in a short space of time, typically less than one second.

 ultrasonic sealing, the heat required for melting is only generated inside the thermoplastic sealing layer. For localized conversion of vibrations to friction heat, the anvil or sonotrode profiles are mostly linear. These profiles ensure focusing of the energy input and therefore short sealing times between 100 and 200 milliseconds.

20Khz Ultrasonic Pistol for Drilling Hole in Fabric. This is ultrasonic plastic standard welding machine. It can be easily customized to fit the exact specifications of the parts being welded. According to customer's special requirements, we can design the suitable horn and bottom modle to finish welding.
