GUILL Tool has announced a new design for its high-production rotary models, both inline and crosshead style. A double increase in speed, with models running to 1,000 RPM depending on the application, are now available in the line of patented rotating tip and die designs. By rotating the tooling in relation to the material flow, a rotary head increases the wall strength of an extrusion, thereby allowing a thinner wall with less material and the corresponding cost savings for the user. Typical applications for rotary heads include medical and multi-lumen tubing plus various high-end extrusions with interlocking layer or multiple striping requirements. Features offered on these new rotating extrusion dies include 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 minimise cleaning downtime. By using rotary dies, extruders can realise cost savings due to the elimination of secondary processes, cosmetic enhancement of the end product with the elimination of weld or parting lines, plus 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.
