SJ Series Plastic Single Screw Extruder Machine
ISO Standard SJ Series Plastic Single Screw Extruder Machine is main part of the core operations in polymer processing and is also a key component in many other processing operations. The foremost goal of a single screw extrusion process is to build pressure in a polymer melt so that it can be extruded through a die or injected into a mold. Most machines are plasticating: they bring in solids in pellet or powder form and melt them as well as building pressure.
Single screw extrusion is one of the methods used for processing materials of synthetic plastics both in powder and molten form. It is mainly used to improve the quality of the melt as well as increase its production by creating pressure in the molten polymer. This forces the extrusion of the polymer. Single screw extrusion is mostly used for polymers that are pure. If they are made of different materials, twin screw extrusion is used. Single screw extruders can either be used as part of a large extrusion system or used as stand-alone machine for extrusion.
The extruder consists of the following: barrel, screw, controls, drive mechanism and arrangement of resin feed. As the screw turns, it moves the resin within the hot barrel. In this way, it reaches the required temperatures as well as mixes thoroughly to form a melt that is homogenous. The pressure which is built up by the single screw extruders then forces the melt from the extruder. It gets out shaped like a die. The whole system has barrier screw that makes sure that the whole resin does not melt in basic extrusion screw
