About Heat Set and Ultrasonic Inserts

Heat set and ultrasonic inserts go in after moulding. The insert is heated, or vibrated ultrasonically, and pressed into a cored hole. The plastic softens, flows around the knurls and undercuts, then sets hard to lock the insert in place. It's quick, repeatable and keeps the moulding tool simple, which is why it's the go-to method on a lot of production lines.

Choosing the Right Heat Set and Ultrasonic Inserts

Hole size, insertion depth and temperature all affect how well the insert holds. Harrison Silverdale can recommend insert styles and hole sizes for your material, so pull-out and torque-out figures are where they need to be.
