MEASURING APPARATUS FOR DETERMINING FLOWING PROPERTIES OF POLYMERIC MELTS

摘要

The invention relates to a device for measuring of rheological behaviour of polymer melts, the device containing a measuring capillary channel arranged in a mould of an injection moulding machine and sensors connected to said measuring capillary channel. In the measuring device, the sensors (7, 8, 9, 10) are arranged in the mould part (1 ) connected to the fixed plate of the injection moulding machine, behind the melt inflow (1 1 ) downstream of the melt, mean¬ while the capillary channel (13) is provided in an insert (12) arranged in a cavity of the mould part (2) connected to the moving plate of the injection moulding machine, facing the sensors (7, 8, 9, 10) and the melt inflow (1 1 ), wherein the sensors (7, 8, 9, 10) are coplanar with the surface of the fixed mould part (1 ) and the upper surface of the capillary insert (12) is coplanar with the surface of the moving mould part (2).
