Basic Principles of Ultrasonic Welding

The two thermoplastic parts to be assembled are placed one on top of the other, in a supportive nest called a fixture.
A titanium or aluminum component called a horn is brought into contact with the upper plastic part.
A controlled pressure is applied to the parts, clamping them together against the fixture.
The horn is vibrated vertically (20,000 or 40,000 Hz) for a predetermined amount of time called weld time.
The clamping force is maintained to allow the parts to fuse as the melted plastic cools and solidifies.
Once solidified, the horn retracts and the joined plastic parts are removed from the fixture as one part.
