EJOT TSSD®
The fastening element for lightweight design
The EJOT TSSD® (thermal adhesive bonding boss / German: Thermischer Stoff-Schluss-Dom) has been developed including the appropriate joining process, in order to realise fastening options for lightweight material. The process is suitable for sandwich elements with hollow core and foam core structures with different top layers preferably with fibre content. The TSSD® can be used as a screw boss for the DELTA PT® screw, or directly as fastening element.

TSSD® installation process
During the joining process, a thermoplastic boss is installed into the plastic component with a defined rotation speed
and axial load. The installation can be done with or without a pilot hole, depending on the component material. Due to the applied axial load the fastening element penetrates the component and the frictional heat caused by the rotation causes a partial fusing of the joining parts. After a brief cooling time a thermal adhesive bond and / or mechanical and form-fit occurs, depending on the material.
