World first: Daimler opts for plastic engine support; replaces aluminum


Daimler is installing the world's first plastic engine support for the six-cylinder diesel engine used in the new GL Class. Compared to the previous aluminum support, the plastic part offers improved acoustical properties, better thermal insulating characteristics and a 30% weight advantage, while being able to withstand the same load.

The part, which supports the engine with the aid of the engine mounts, is molded from Ultramid A3WG10 CR, a highly reinforced specialty polyamide (PA) from BASF (Ludwigshafen, Germany) that has been optimized for high mechanical loads. Joma-Polytec (Bodelshausen, Germany) was responsible for designing the injection mold and producing the plastic engine support....
