EXTRUSION: Rotary extrusion dies offer two-fold increase in speed

摘要

Guill Tool & Engineering Co.Inc.announces a new design for its high-production rotary extrusion dies-both inline and crosshead style-that offer 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.A two-fold increase in speed,with models running to 1,000 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 the material flow,a rotary head increases the wall strength of an extrusion,which allows 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.
