We currently use a single screw extruder, two stage screw and for the most part it seems to run fairly well except their is some venting issues. All I can say it is a metal loaded polymer with a 4-6.oo specific gravity that we premix before running through the extruder. I would like to know is why some one would choose a single screw over a twin screw, one stage vs two stage screws and their pros and cons. I am new to this forum and any information would help and maybe help out others.
