Dieffenbacher Show D-SMC Process

07 August 2010

At K2010, Dieffenbacher will be showing its new direct D-SMC process for producing thermosetting structural and class A components in the automotive industry.

Dieffenbacher developed the new D-SMC process in a consortium together with DSM and the Fraunhofer ICT. The technology of direct compounding bypasses the costly steps of wrapping, storing and logistical handling of the SMC semifinished part which used to be required. The material composition can also be adapted online to meet different requirements.

The company will also be presenting a complete system for the high-pressure resin transfer moulding process (HP-RTM) for manufacturing carbon-fibre composites.

Dieffenbacher developed this process together with its Joint Venture partner, KraussMaffei. The carbon fiber mat is is placed in the bottom die of a vertical press, and the subsequent process of filling with epoxy resins or polyurethane is performed using high-precision mixing heads, directly flange-mounted on the mould. As a result, both companies are for the first time offering global turnkey solutions for high-pressure resin transfer moulding processes that are available from a single source.
