Description
This machine, appropriate for the mixing processing of high polymers, such as engineering plastics, modified plastics and color masterbatch etc., is featured by uniform dispersion, plasticizing coloring and filling modification. The pressure transducer in this product can accurately measure the pressure variation in front of and at the back of the melt pump. The human-machine interface operating system controlled by the calculator can readily set and display all technological parameters with the visual interface, accurate data and automatically calculated pressure value, enabling the blending quality of color masterbatch or composite materials more accurate and more standard.
