Sonic-Sert - UHBRSO
The Sonic-SertTM has been designed for post mould installation into thermoplastics using heat or ultrasonics.
With the opposing knurls providing a combination of high pull out and torque resistance.
Heat instalation
Where 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 power 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:
- Rapid installation
- Allows for thin walls in the boss
- High pull out and torque resistance
