Cold feed Rubber Laboratory Extruder Type EEK 32.12 L - 4/90, incl. 2pc.. Heating/Cooling Units

We are pleased to offer our Laboratory Standard Extruder with ASTM Garvey die and rheometer head for determination extrudability, die swell and dirt content as well for determination of shear and strain viscosity of compounds. This for the testing procedure in compound development and in quality control. The machine is in principle equiped with all technical features of a production ex-truder and advanced measuring and data processing hard and software.
