ment system that significantly reduces
pressure on the tooling, allowing easier
and more precise concentricity adjust-
ments without loosening the face bolts.
Easy-Out inserts for the adjusting bolts
also allow simple replacement of locked
or damaged adjusting bolts, which fur-
ther saves on repair and downtime.
Another innovative feature of this new
rubber/silicone crosshead is a cast alumi-
num liquid-fed cooling sleeve that allows
the user to switch out the cooling jacket
in the event of a line obstruction, again
reducing downtime compared to tradi-
tional integrated cooling systems.
The new 500 Series crosshead with
MAGS gum space adjustment is a drop-
in replacement on most existing NRM
n Guill Tool introduces the new 500 Se-
ries crosshead with MAGS gum space
adjustment. The 500 Series is designed
specifically for the flow characteristics
and unique processing challenges of
elastomeric compounds. One of the key
features on this new crosshead design is
the mechanically assisted gum space
(MAGS) adjustment system. This new
method of gum space adjustment allows
the operator to make an effortless ad-
justment from a single point using a
common socket wrench. No more need
to struggle with multiple nuts and bolts
in order to adjust gum space, which
leads to faster adjustments. The visual in-
dicator on the core tube allows the ope-
rator to see how far the gum space has
been moved, making those adjustments
much more accurate and repeatable.
The hardware-free and patented cam
lock design of the new 500 Series means
no time is wasted unbolting and re-se-
curing fasteners for disassembly and re-
assembly. Only half of a rotation of the
cam nut is required to loosen and auto-
matically extract the deflector from the
head body, which is another time saver.
Also, with no undercuts on the deflector,
there are no material hang-ups when ex-
tracting the deflector, allowing for faster
and easier cleaning and changeover.
The new 500 Series also features the la-
test Center-Stage concentricity adjust-
New 500 Series Rubber/Silicone Extrusion Crosshead
lines, however this crosshead design can
also be adapted to fit any extruder de-
sign or line layout.
The addition of a newly designed flow
inlet channel reduces the shear and heat
that is generated as the materials are
being processed. This leads to lower
head pressures allowing the material to
move through the head in a much more
balanced and even flow.
All crossheads supplied by Guill are fur-
nished with a tool kit for assembly and
disassembly as well as a detailed opera-
tor’s instruction manual.
