Jan 29, 2016 · For an extruder utilizing screw cooling, the rotary union and siphon tube assembly and hoses must be removed. Then use the screw extractor mechanism attached to the extruder gearbox to push the screw forward in the barrel. Push the screw until about four or five turns are exposed for cleaning (Fig. 2). What is Extrusion? Plastic Extrusion Process Elastron Barrier screws, especially for Elastron V products, are used successfully and are recommended. In order to change the melt flow from rotational to uniform laminar flow, there is a relaxation zone after the extruder barrel. During extrusion, the melt inside the barrel is compressed and stressed, and it requires uniform flow before profiling.Home - American Screw & BarrelProducts.
