ABSTRACT:
A method for securing a thermoplastic part to another part by applying ultrasonic energy to a projection of the thermoplastic part in a direction substantially normal to the longitudinal axis of the projection. The exposed end of the projection is urged into an open cavity disposed in a side wall of a horn adapted to undergo ultrasonic vibrations. The cavity further is disposed substantially at an antinodal region of longitudinal motion of the horn and oriented normal to the direction of longitudinal motion of the horn. The horn is rendered resonant along its longitudinal axis while the exposed end concomitantly is urged into the cavity.
