What are the machinery needed for plastic processing?
In the case of an extruder, there are three kinds of resistance to overcome: the friction between the solid particles (feed) on the cylinder wall and the friction between them when the screw rotates several times (feed zone)
The screw is actually a bevel or slope, wound on the center layer.
Profiles, etc., can also be used for plastic modified granulation. The basic mechanism of extrusion is very simple - a screw in the cylinder rotation and the plastic forward.
Extruder is the role of the screw in the molten plastic through a fixed shape of the extrusion port extrusion, under the action of the tractor after the water-cooled after cutting. Mainly used for a variety of the same cross-section of a large number of continuous production, such as tube
The adhesion on the cylinder wall; the flow resistance of the melt when it is pushed forward.
