SME element is a mixing element in which a number of reverse shallow reflux slots are opened on the conventional forward conveying element. Usually used together with resistance elements, the material is conveying through a shallow groove on the edge to form a return flow of melt, improving the distribution ability.
Selection principle: Usually used in the melting zone.
The basic working principle of the extruder screw and barrel is to melt and compact the polymer, push it to the mold at constant pressure, constant temperature and constant speed, and form a parison i...
