Powder Coatings Laboratory Scale Twin Screw Extruder
Description: This machine is suitable for the mixing and processing of engineering plastics, modified plastics, masterbatch, titanium dioxide and other high polymer. It has the characteristics of even dispersion, plasticizing and coloring, filling and modification. The pressure sensor of the product can accurately measure the pressure change before and after the melt pump. The computer-controlled human-machine interface operating system can easily set and display all process parameters. The interface is intuitive, the data is accurate, and the pressure value is calculated automatically, which makes the blending quality of masterbatch or composite more accurate and standard.
