Nanjing Gorray has developed single screw extruder with some new features, most of which are targeted for energy-saving, high productivity and easy control.

·Advanced screw design to optimize the output and keep melt at lower temperature;

·Overload protection by reliable flexible coupling;

·Accurate temperature control system;

·Convenient erection & adjustment

Single screw extruder is one of the core extrusion equipments in polymer processing and is also a key component in many other processing operations. The preliminary aim of a single screw extruder is to build pressure in the polymer melt. With sufficient pressure the melt can be extruded through a die or injected into a mold. A single screw extruder brings in solids in either pellet or powder form and melts them as well as building the pressure.

Thus a single screw extruder is widely used for direct extrusions such as sheet extrusion, film extrusion, pipe extrusion, tube extrusion and profile extrusion.

In some cases, those pro-water polymers such as PET, PMMA, PC need venting or vacuum. So a high efficiency venting system will be furnished. In plastic recycling process, venting of a single screw extruder turns out to be a necessity.

A single screw extruder can be a good match for twin screw extruder, which is herein referred to as dual stage extrusion line in Nanjing Gorray, a new experienced extruder supplier in China.
