Vibration welding has a short process time and is suitable for parts with large joint areas or made of materials that are difficult to process.
The following were tested: 1) the influence on the final bond of the vibration welding time; 2) the contact holding time after the welding vibration stopped; 3) the welding pressure exercised on the surfaces; 4) the holding pressure after the welding vibration stopped; 5) the amplitude of the shift imparted to a surface relative to the other during vibrational welding.
Vibration welding is one of the most widely used technologies to join thermoplastic parts in manufacturing industry.
