Single screw extruder is divided into transmission period, compression, metering section.
By screw diameter, pitch, the depth of screw to determine three parts of effective length, generally divided each accounted for a third.
First period for the delivery period: the material mouth at the end of a thread, the material can't plasticizing, here but to preheat the crush.
Second call compressed paragraphs: screw grough by gradually decreases, and the plasticizing degree temperature to achieve material.
The third paragraph is plasticizing temperature measurement period of material stay here, just like metering pump, accurate and quantitative transport, melt materials supply to the nose, the plasticizing temperature, the temperature cannot be lower than average slightly high.
The SJ Series single screw extruder is suitable for processing PP, PE, PP-R, ABS and other plastics.
Equipped with auxiliary machines, it can manufacture profile, pipes, sheets and other plastic products and granulation.
It has the advantage of simple production technological process, high output, stable quality and low cost.
