Ultrasonic insertion is the best solution when a threaded bush needs to be encapsulated into a plastic part.
How does ultrasonic insertion work?
In the ultrasonic riveting process, a hole, marginally smaller than the O.D. of the insert, is pre- moulded in the plastic part.
This serves to guide the insert while providing a certain degree of interference.
The insert is designed with serrations (for high torque strength) and undercuts (for high pull-out strength) or both (for high pull-out and high torque strength).
The ultrasonic energy applied to the insert travels to the interface, creates frictional heat and melts the plastic. The melt flows into the serrations and undercuts of the insert, resolidifies and locks it into place, providing excellent torque and/or pull out strength.
