compomix FI: composite fibre impregnation

For filament winding, RTM and pultrusion processes

The compomix FI has been specially designed for the impregnation of fibre rovings in filament winding, resin transfer moulding (RTM) and pultrusion processes. It ensures the precise metering and mixing of two-component material used for glass, aramid or carbon fibre impregnation (FI). Depending on the application specifics, the compomix FI can be used to either fill a resin bath and keep it at fill level, or to inject material directly into a mould. The material is supplied from two material tanks installed on the system. The tanks are filled directly from the original delivery containers and this is done automatically either via standard refill systems or gravimetry.
