The main control unit of the torque rheometer cooperates with each functional unit, and can freely assemble a full-functional production simulation system of several laboratory sizes to simulate the actual production and processing process of polymer materials according to the production process requirements of polymer materials. Such as polymer formulation, blending, extrusion product forming, on-line detection and other integrated production process simulation system. It is composed of measuring and controlling host, parallel twin screw extrusion platform (with multiple volume feeding), melt pump, product forming machine (for example, calender, tape casting machine, film blowing machine, cable cladding machine, granulator, etc.) and on-line testing equipment to realize integrated simulation production process.
