Principles of Helicoid: Balance Flow "Distribution"
The Helicoid design incorporated in the Genca crosshead provides a balanced flow of the extrudate which is distributed evenly over the wire conductor or tube extrusion. This uniform distribution is maintained regardless of changes in the extruder’s RPM. Through the assistance of a mechanically balanced device, referred to by Genca as a Helicoid, the manufacturer is now given a build-in control over the process. This allows the user to reduce the amount of excess material in order to achieve a concentric cable that has a uniform wall thickness.
