Insertion unit TSS

Thermal adhesive bond
The TSS system enables placement of plastic bosses (domes) in sandwich structures with honeycomb or foam core and fiber-reinforced polymer covers (e.g., CFRP, GFRP). During the TSS joining process the plastic components are melted to form a thermal adhesive bond. Placement can be carried out with or without a pilot hole and can be robot-assisted.

Process & application
The TSS process is applied as a robot-assisted system or as a closed setting facility within a cell. Plastic bosses are used directly as fasteners or as robust threaded inserts for self-tapping screws. The entire process is freely configurable and can be documented. Suitable for assembly tasks with access from one side only.

Individual parameters
Individually adjustable process parameters with monitoring and high-resolution process evaluation. Initial material assessment, feasibility studies and evaluation of completed joints are performed in WEBER's in-house laboratory.
