Plastic extrusion screw design and types of extrusion. 1) pak600 extruder requires two drops. one drop for the control cabinet and one drop for the drive cabinet. one drop for the control cabinet and one drop for the drive cabinet. 2) maximum amp load is based on the standard ac motor & drive + the number of barrel and die zones (shown above).. Of the screw. given that single screw extruders deliver the polymer gravimetrically under its own weight (gravity fed), can be achieved by optimising the screw design. most extruder screws have a large length to diameter (l/d) ratio to enable process optimisation. many modern machines of today have l/d ratios of at least 32:1 or higher. long extruders with associated wide operating windows.
