According to the latest publication of the Krauss Maffei website:
Drastically reduced cycle times and processes ready for large-scale production – Developing new technologies and applications for the fiber-reinforced lightweight construction is front and center at the Composite Centre of the University of Sheffield Advanced Manufacturing Research Centre (AMRC) in the United Kingdom. The institute is expanding its expertise especially in the field of highly reactive and fast-reacting resin and hardener systems using the new KraussMaffei RimStar Compact for the HP-RTM process (High Pressure Resin Transfer Molding).
New HP-RTM line at the institute AMRC
The new KraussMaffei RimStar Compact at the AMRC ranks among the world’s largest, most state-of-the-art and flexible of its kind for the HP-RTM process. “The specific selection of two dosing units and the corresponding mixing heads allows for a particularly precise mixing of the resin system. This makes the system the first of its kind in which multiple mixing heads are used in the full scope of functions in order to enable a perfect cavity fill. Even materials that are highly reactive and fast-reacting at the same time—which are increasingly in demand for the HP-RTM process—can be reliably processed,” explains Sebastian Schmidhuber, Head of Development for Reaction Process Machinery at KraussMaffei. Processing such highly reactive matrix materials opens up entirely new development opportunities for composite materials and components with more intricate geometric structures. “The curing times are critical here. Using highly reactive systems, they can be reduced down to three minutes. With such short times, they offer great opportunities for the manufacturing industry,” adds Darren Wells, Research Engineer at AMRC.

Another advantage of KraussMaffei’s new RimStar Compact, from both a process technology and cost-effectiveness standpoint, is its compact design. Matrix material injection and curing take place in one and the same mold. This results in a consistently high quality of the components and in high process reproducibility.
