RAMPF has launched RAKU-TOOL EI-2500 and EH-2973 setting new standards in RTM and resin infusion production processes leading to high class surfaces.
According to RAMPF, fibre-reinforced thermoset plastics are becoming increasingly important. In order to minimise energy consumption, the aim is to reduce the weight without this affecting the mechanical resilience. It says that consequently, more and more composite components are being used in the automotive, aviation, and leisure industries. With its new EPOXY INFUSION SYSTEM RAKU-TOOL EI-2500 / EH-2973, RAMPF Tooling Solutions is setting new standards in surface quality and processing properties.
Unlike metals, RAMPF says that high-performance components produced from fibre composites make even small- and medium-series production profitable – especially when using resin transfer moulding (RTM) and resin infusion (RI). RTM is ideal for small- and medium-series production, while RI is mainly used for small series, prototypes, and moulds.
Both processes produce components with excellent mechanical properties – with a typical fibre content by volume of around 50-60 percent – and a minimal variation in thickness. Complex geometries are also possible.
“The main advantage of the RI process lies in the high component quality, especially in terms of air pockets,” says Marcus Vohrer, Head of Application Engineering at RAMPF Tooling Solutions. “The RTM process scores particularly highly on process reliability and reproducibility. Occupational hygiene isn’t an issue for either process, because there’s hardly any contact with chemicals for staff,” he adds.
The advantages for users of the new epoxy infusion system RAKU-TOOL EI-2500 / EH-2973, which was developed specifically for RTM and RI, are described as follows:
Top-quality surfaces: Class A+ surfaces possible.
Tg 138°C: Post-curing at just 120°C delivers optimum temperature resistance.
Excellent processing properties: Ideal pot life for reliable processing, impressive degassing and flow properties under vacuum, good wetting properties, and the possibility of long flow paths – for a reduced set-up time, lower processing costs, and fewer pinholes.
Curing at room temperature: Good stability after overnight gelation (no brittleness), easy demoulding without pre-curing or part deformation, and the part can be processed/finished straight away.
