Evonik develops technology to mass-produce complex moulded parts

The automotive industry is increasingly looking to composite materials as a way of reducing vehicle weight and CO2 emissions. Up to now, however, these materials have mostly been used in luxury-class vehicles, as established methods are expensive and complex. With Evonik’s newly developed PulPress method, however, manufacturers can now mass-produce complex moulded parts at a reasonable price, taking the technology from the high-end market to large-scale production.

The new method combines two traditional production techniques: compression moulding and pultrusion. Combined together, they make automated, continuous production of composite parts possible. 

The most important raw material in the process is Rohacell,
