More About Our Heat/Ultrasonic Inserts

Heat Installation

Heat installation involves positioning the insert into the molded or drilled hole. A heated tip is then inserted into the inside diameter of the threaded insert. Localized melting begins to take place and with the downward pressure, the insert begins to install. Plastic flows into the varying undercuts and knurls. Benefits of thermal installation include: installation of multiple inserts at a given time, ability to install inserts beyond ¼”, and superior strength assemblies.

Ultrasonic Installation

Ultrasonic Installation involves positioning the insert into a molded or drilled hole. An ultrasonic horn then contacts the insert and begins to vibrate the insert. This vibration creates frictional heat which melts the plastic allowing the horn to lower the insert into position. Once installed to the appropriate depth, the cycle is repeated for the next insert.
