Twing-screw-shafts

Segment-carrying shafts are the heart of co-rotating screws and play a crucial role in the functioning of these mechanical components. These shafts are characterized by their remarkable lengths, which in some cases can exceed 50 times their diameter, indicated as 50D.

A segment-carrying shaft must possess exceptional resistance to torsion, being responsible for the rotary movement of the screws. At the same time, it must maintain a certain ductility, that is, the ability to deform without breaking, to withstand the mechanical forces exerted during the extrusion process.
