Viscosity of moulding compounds

Pressing rheometer for the determination of the shear rate dependent viscosity of fibre reinforced moulding compounds


Squeeze-flow measurement with constant surface area


Derivation of viscosity with e. g. power law based material models and different compression rates


Temperatures from room temperature up to 200 °C


Individual heating times in the mould prior to pressing as well as pre-heating times of the compounds


Determination of temperature distribution in the material depending on the heating and pre-heating times


Determination of process parameters, e. g. start of chemical reaction


For: Reactive moulding compounds like SMC, BMC, thermoplastic moulding compounds like GMT
