In March 2011, the first Dieffenbacher high-pressure RTM press entered service at Audi in Neckarsulm. Amongst other activities, the Audi Lightweight Construction Center is working on manufacturing structural components from carbon for future lightweight concepts.

Two factors set the new high-pressure RTM press apart: the congruent bending line of the moving bolser and ram, as well as the high-precision parallel motion even with off-center forces. Both these are decisive when it comes to first-class component quality. The press has special press programs for IMC and RTM with flow-front control. Flow-front control presses the injected resin into specific component areas within the closed tool, for example where the material is needed for reinforcements. With press forces up to 10,000 kN and table sizes of 2800 mm x 1800 mm, the Compress Eco is designed both for developing new technologies and for undertaking small batch production.



In cooperation with its partners Fraunhofer ICT and Krauss Maffei, Dieffenbacher is working to develop innovative process and machine concepts in the RTM field.
