Dieffenbacher Highlights DuroVision Project at K-2007

24 October 2007

At K 2007, Dieffenbacher will be presenting the DuroVision development project sponsored by the bmb+f- (German Federal Ministry for Education and Research).

The partners in this are the Fraunhofer Institute for Chemical Technology, RESPECTA Maschinenbau GmbH, Projektträger Jülich (PTJ), M-Base Engineering + Software GmbH, BYK Chemie GmbH, Reichhold, POLYTEC Composites Germany GmbH and Johns Manville.

The objective is to manufacture components from fiber-reinforced thermosetting plastics in the direct process. Reproducible manufacturing of compounds and components in one process step represents significant progress in development that makes using this material more attractive and increases the range of applications. DuroVision has now achieved material characteristic values that make it suitable for conventional SMC applications. Above all, it has achieved quality values corresponding to the requirements for Class A surfaces.

Using combined extrusion and pressing systems for the LFT-D-ILC direct process, it is possible to process rovings and plastics directly and to produce lightweight components for the automotive components industry. Crash-resistant lightweight structural components with a cosmetic surface can be manufactured using advanced and ground-breaking ""tailored LFT-D"" technology, without incurring the high costs of the semifinished product stage. The rear door of the new smart fortwo is a component with localized reinforcements for the best possible structural properties that is manufactured using this process. The special thing about this cosmetic component is that it does not have to be painted. The Dieffenbacher extruder system permits in-line blending of a paint batch.

Dieffenbacher will be presenting its products and services at the K 2007 in Düsseldorf from 24 to 31.10.2007 in Hall 14, Stand 14A04.
