二、Components and function
1、Mainframe：Receiving signal and sending data control temperature and mechanical transmission, real-time mapping pressure -time, temperature-time, torque - time curve reports and so on.
2、Mixing unit：Divided into 60ml and 300ml of two kinds, the former mainly complete material characterization of rheological measurements, the latter complete material mixing and plasticizing, can be used as mixed material research. Equipped with three kinds of rotors with shear capacity. Make the material and rotor execute mixing shear by the same speed but opposite direction force to the chamber wall.
3、Extrusion unit：Simulate actual processing equipment to evaluate material processing performance. Can also cooperate with capillary die under the different shear rate, to measure real viscosity of melted plastic and the objective characterization of material fluidity.
4、Other parts：Traction, calendering, blown film, automatic measuring and weighing are optional, in order to complete the material modification, the measurement of impurities, such as tensile rheological study.
