EJOT TSSD® Aero Reliable and lightweight insert technology for sandwich materials The automotive trend subject "lightweight design" was the starting point for the development of TSSD® technology ("Thermischer Stoffschlussdom") for sandwich materials with honeycomb and foam core structures and their various top layers. The TSSD® is a product which is completed by the corresponding installation process to join components made of the mentioned lightweight materials in a reliable way and with outstanding strength properties. For applications in the aerospace industry, the TSSD® product and the joining process were further developed and redesigned - resulting in the TSSD® Aero variants.

Functioning of the TSSD® > The TSSD®, rotating at a defined speed and pushed down by a forced feed with the installation tool, will be grated through the top layer of the sandwich material by breaking the layer partially through friction and heat to enable a controlled penetration of the TSSD® element. > The frictional heat softens the TSSD® material at the edge layer which will then spread inside the sandwich and connect to the structure. > After reaching the end position the rotation immediately stops without overrun - the setting tool continues to exert pressure on the joining element so that the softened plastic mass in the component can solidify completely in the final position. > After removal of the installation tool the component with the joined TSSD® can directly be used for further processing.
