IMIL
Cross-sectional view of an integral multi-component seal with three functional zones: preloading (elasticity), sealing contact pressure (wear-resistant, low-friction, elastic), and support/guidance (wear-resistant, pressure-resistant).
In the joint project IMIL, WESTRING Dichtungstechnik GmbH (WRD) and the Institute of Lightweight Engineering and Polymer Technology at TU Dresden are developing the fundamentals for integral, one-piece multi-component sealing systems for rotating applications that can be manufactured in a multi-component injection molding cycle. The aim is to significantly reduce friction and wear losses - friction-induced energy consumption - by using tribologically optimized material compounds as well as a functionally integrated seal design, while simultaneously avoiding the assembly and post-processing effort associated with conventional multi-part solutions. The focus is on rotary seals with distinct functional zones (preload, sealing function, support/guidance) that are permanently joined.
Schematic principle of an integral multi-component (multi-shot) sealing system, as well as the functions of the individual components and the material properties required for each.
