1) Initial assembly: Parts are secured within a specially designed fixture to ensure precise alignment during the welding process.
2) Engagement of horn: The horn interfaces with the upper part, exerting downward pressure towards the fixture with an electric press. This horn transmits mechanical vibration to the parts.
3) Welding process: The horn initiates high-frequency vibrations (typically 20 kHz) that transmit mechanical energy to the components, generating heat at the interface and facilitating fusion.
4) Cooling phase: Post-welding, vibrations stop while the pressure is sustained, allowing the fused components to cool and form a durable bond.
5) Completion: Once the weld cools and solidifies, pressure is released and the horn is retracted, freeing the newly welded component from the fixture.
