About screw elementMatierials: W6Mo5Cr4V2 or 38CrMoAlATreatment: Quenching and nitridingDiameter: 14 mm to 320 mmContain kneading block and conveying elementThe basic element of co-rotating twin screw extruders is the tightly intermeshing conveying elements with an Erdmenger profile. The elements bear against each other closely and the extruder cylinder, creating a stripping effect.
The following basic dimensions can be varied here according to their interdependency:OD/ID ratioOuter diameter and inner diameter matched to the required OD/ID ratioFlight pitch of the screwLength of the elementMachine-specific clearances between the element and the barrel hole or the element and the adjacent element.By screw elements, we mean single or multi-flight feed screws for transfering products or melt. Depending on the machine output, different ratios of outer diameter to axis clearance can be used In the case of low OD/ID ratio extruders, 1 to 3-flight profiles are possible, although current deeper cut models are generally fitted as standard with double-flight elementsScrew element
