EXTRUSION: Rotary Dies Run At Higher Speeds

New tool also said to improve wall strength of extruded tubing.

Guill Tool, West Warwick, R.I., has introduced a new design for its high-production rotary dies in both inline and crosshead style that reportedly offer a twofold increase in speed. Models are available with running speeds to 1000 RPM, depending on the application. By rotating the tooling in relation to the material flow, a rotary head increases the wall strength of the extrudate, allowing a thinner wall with less material and the corresponding cost savings for the processor.   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; and optional quick-change cartridges that minimize cleaning downtime.  

By using rotary dies, processors can realize a 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 offers its new high-speed rotary models as turnkey packages, complete with die cart, tools and all accessories for installation and maintenance.
