The UK National Composites Centre (NCC) has expanded its TechCenter with a new KraussMaffei RimStar Compact 4/4/4 mixing and metering machine.
The system is equipped with two mixing heads, enabling it to process both epoxy resin and polyurethane in high-pressure resin transfer moulding (HP-RTM).
“High-pressure injection using the RimStar Compact allows us to process fast-reacting resin systems. This shortens cycle times, enabling us to produce fibre-reinforced components in large quantities,” explains Wolfgang Hinz, Product and Sales Manager, Composites and Surfaces at KraussMaffei.
“Previously, the HP-RTM process primarily used epoxy resin as the matrix material. Recently, however, an increasing number of components are being made of polyurethane in the HP-RTM (high pressure RTM) process. Because the RimStar Compact 4/4/4 can process both matrix systems, it gives the NCC and its member companies great flexibility for carrying out application-oriented test series.”
According to NCC, a critical argument in favour of HP-RTM technology was the fact that KraussMaffei’s experts already have extensive experience in implementing the process in series production. This served as the basis for the highly skilled advice provided to the institute with regard with regard to the design and application options of the metering machine.
