Dieffenbacher Develops Automated Production Line

06 September 2011

Dieffenbacher, with the help of KraussMaffei, has developed a completely automated production line for the HP-RTM process, starting from preform manufacture and extending through to the pressing process and ancillary steps.

This development makes series production of high-strength structural components and outer body panels possible using carbon fibre-reinforced plastics (CFRP). Previously, CFRP production involved a high level of manual labour, and was only used in aviation and spaceflight applications as well as in premium category automobiles.

Dieffenbacher will be showcasing their capabilities at the upcoming Composites Europe. They will also showcase the patented direct process for SMC (D-SMC). Dieffenbacher say the technology of direct compounding permits continuous manufacture of SMC compounds, followed directly by processing into a component in the extrusion process. They explain that this means there is no need for the cost-intensive stages of wrapping, storage and logistics previously required for the semi-finished SMC part. The maturing time used to take several days, and eliminating this delay represents an immense advantage of this one-stage process in terms of time and costs. As a result, the processing time between the raw materials and the finished part is reduced to a matter of minutes.

Dieffenbacher regards its technologies for processing fibre-reinforced plastics as an important milestone in lightweight construction concepts for use in the automotive industry and other industries besides.

Dieffenbacher will be exhibiting in Hall 4, Stand C36.
