BD-8860-B single screw extruder pellet cutting unit/PLC programmable type
This machine is suitable for mixing, plasticizing, and extruding 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. Suitable for laboratory testing and quality control, teaching research, and small-scale production, it can directly extrude pellets, sheets, pipes, etc. to simulate various production processes.
