Abstract
A device which is capable of measuring both the viscous injection/casting operation and the shrinkage during the solidification phase, using a suitable measuring device. For this a sensor is fitted in the mould at the critical point expected, with a measuring surface that is flush with the inner wall and is able to measure shear and compressive stresses, so that for the first time the shrinkage phenomenon becomes measurable. With this, a new dimension of quality monitoring becomes possible.
