Extrusion technology company Guill Tool has introduced a new design for its high-production rotary models, both inline and crosshead style, that delivers a twofold increase in speed. Models running to 1000 rpm, depending on the application, are now available in the Guill line of patented rotating tip and die designs.
By rotating the tooling in relation to material flow, a rotary head increases the wall strength of an extrusion, thereby allowing thinner walls with less material. Typical applications for rotary heads include medical and multi-lumen tubing plus various high-end extrusions with interlocking layer or multiple striping requirements.
The new rotating extrusion dies include such features as counter-rotating tip and die, co-rotating tip and die, rotating die with conventional tip, rotating tip with conventional die, crosshead or inline, multi-layer, striping, certain profiles, and optional quick-change cartridges that minimize cleaning downtime.
By using rotary dies, extruders can realize cost savings owing to the elimination of secondary processes, cosmetic enhancement of the end product with the elimination of weld or parting lines, and a reduction or complete elimination of ovality.
Guill Tool offers its new high-speed rotary models as turnkey packages, complete with die cart, tools, and all accessories for installation and maintenance.
