  In Ultrasonic welding, high frequency sound energy is used to bring the joining surfaces of two thermoplastic parts to a molten state where they can be permanently welded together. 1. The horn, under pressure from the assembly stand, contacts one of the two mated plastic parts. 2. Vibrational energy from the horn causes the contacted plastic part to vibrate against its mate. 3. The mechanic...

  Often people mistake vibration welding for ultrasonic welding and vice versa. This is because both methods utilize vibrational force to weld plastic assemblies. However, the reality is that both these welding techniques are very different from each other.   The vibration welding method pulsates in a linear side-to-side movement with one part proportional to another. The friction betwee...
