Vibration Welding Guide - DSM

6 Vibration Welding Guide 2.1 Basic principles In vibration welding, two plastic parts are in frictional contact with each other with a certain frequency, amplitude and pressure. As a result of the friction between both parts heat is generated which causes the polymer to melt at the interface. Due to pressure, the molten polymer flows out of the weld-zone giving rise to flash, see Figure 1 ...

What is Vibration Welding? Dukane

Linear vibration welding physically moves one of two parts horizontally under pressure, creating heat through surface friction that melts and welds the parts together. Compared to ultrasonic welding, vibration welders operate at much lower frequencies, higher amplitudes and much greater clamping force. Linear vibration welding is designed with electromagnetic heads that eliminate the wear and ...

Vibration welding of thermoplastics - Wikipedia

Vibration welding (also known as linear or friction welding) refers to a process in which two workpieces are brought in contact under pressure, and a reciprocating motion (vibration) is applied along the common interface in order to generate heat. The resulting heat melts the workpieces, and they become welded when the vibration stops and the interface cools. Most machinery operates at 120 Hz, although equipment is available that runs between 100–240 Hz. Vibrationcan be achieved either through linear vi
