嵌件植入
将嵌件固定到塑料件上的工艺。嵌件直径略大于塑料件上的孔径。当变幅杆将嵌件推入孔中时，超声振动使塑料熔化并绕嵌件外表面的凸棱或滚花流动。 塑料凝固后，塑料与嵌件之间形成机械连接。操作得当的情况下，该连接的残余应力较低。
Inserting
A process of securing an insert to a plastic part. The insert diameter is slightly larger than the hole in the plastic part. As the insert is pushed into the hole by the horn, the ultrasonic vibration causes the plastic to melt and flow around the ridges or knurls on the outside of the insert. When the plastic solidifies, a mechanical joint forms between the plastic and the insert. When properly performed, this joint has low residual stress.
