Heat Versus Ultrasonic Installation

The focus of this article is on two of the most commonly used Insert installation methods in thermoplastic parts: heat and ultrasonic installation.

As the usage of plastic parts has increased in a wide array of industries, the methods for fastening have become increasingly important. When screws or bolts are threaded directly into plastic components, failures can occur due to stripped threads or plastic creep1. In situations where joint strength and the ability to assemble and disassemble without degradation of components is required, Threaded Inserts provide a serviceable thread which satisfies both of these needs. ■
