Tech-Sert - UHBRTE
Tech-SertTM has been designed for installation into thermoplastics using heat or ultrasonics.
With the opposing knurls and vanes providing high levels of pull out and torque resistance. The symmetrical design means the insert can be installed either way round which allows for automated installation.
Heat installation
If heat is used, you must ensure that the insert softens, but does not melt the plastic, which helps avoid flash forming around the top of the insert.
Ultrasonic installation
Ultrasonic installation works best with low amplitude vibrations and enough energy to soften the surrounding plastic.
Care should be taken to avoid excessive downward pressure being applied during installation which can result in the insert being forced into the hole rather than allowing the plastic to soften around it.
Advantages:
- Quick installation
- Symmetrical design for automated installation
- Allows for thin walls in the boss
- High pull out and torque resistance
