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.
