News from Koller Group K.I.T. – KOLLER innovative process technologies CFRTP Technology by Koller Since the beginning of 2023, KOLLER has been producing and supplying a unique structural component for the chassis of the BMW IX to the BMW plant in Dingolfing. The industrialization of the so called CFRTP-Heckfensterrahmen was implemented in close cooperation with BMW Landshut very successfully within a very short time. All production lines were built completely new, special attention was paid to energy-efficient systems. The Heckfensterrahmen is a so called bionic structural component in hybrid skeleton lightweight design. KOLLER became the world’s first TIER1 series supplier to produce automotive structural components in this technology alongside BMW itself. The Heckfensterrahmen is built as a thermoplastic composite with steel parts and carbon fibre this makes it very special and unique. The carbon fibre is embedded in a thermoplastic matrix and only used in a load path-oriented manner. The system itself is 100% recyclable and reusable. The use of materials is reduced to a minimum – thanks to load-path oriented geometry. The parts are produced with 100% green electricity in our plant in Lupburg. The technology goes hand in hand with the GREEN KOLLER strategy and contributes a significant step towards C02 neutral production.
