About product

Jul 25, 2018 · the screw has various geometric features which causes the plastic to transform. the plastic enters the extruder at a given temperature and it must be raised to a certain temperature to flow. this is achieved through shear and exposing the plastic to the heated barrel surface; the screw does all the work to the plastic.
The screw is an essential component of a plastic extrusion machine. through its turning motion inside a tight fitting barrel, the screw conveys the plastic, melts it and forces it through a die. these three steps are carried out in a continuous process capable of producing extrusions in a variety of lengths.
University of toronto professor steve balke routinely does the impossible: he and his graduate students observe polymers inside an extruder barrel. the technology which makes it possible is a glass-walled extruder built as part of a project sponsored by mississauga-based macro engineering (186), whose object is to better understand the dynamics of polymer and polymer-additive mixing in extruders.
