BD-8858-BGLaboratory single screw extruder//Filtering test

This machine is suitable for mixing and processing high molecular weight polymers such as engineering plastics, modified plastics, and color masterbatch. It has the characteristics of uniform dispersion, plasticizing coloring, and filling modification. The pressure sensor included in this product can accurately measure the pressure changes 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 automatically calculated, making the blending quality of color masterbatch or composite materials more accurate and standardized.
