testing and production, Guill built its
own rheology lab in their facility in West
Warwick, Rhode Island, USA. The lab
features several key machines that en-
sure optimum results, when testing ma-
terials, especially new compounds to be
extruded. The testing equipment in-
Guill Tool, manufacturers of extrusion
tooling for the global market, has
opened an in-house rheology laboratory,
making it the only extrusion tooling ma-
nufacturer in the industry with such a ca-
pability. Seeking to obtain better results
and minimize the time it takes between
In-House Rheology Lab launched
cludes a Hybrid Rotational Rheometer, a
Differential Scanning Calorimeter, and a
Thermal Conductivity Meter.

Main features and improvements:
The hot/cold mixing combination got as
beating heart a five stages high intensity
mixing tool in stainless steel with tungs-
ten carbide coating for wear protection.
It also has inclined blades to ensure the
best mixing vortex: 20° of inclination for
the upper stage and 30° the lower stage.
Both Heating Mixer and Cooler are with
all surfaces in contact with the process
material mirror polished in order to re-
duce cleaning and maintenance times
and to avoid residues at the end of mix-
ing cycle in order to eliminate any conta-
mination issues when changing formula-
tion and process conditions batch to
batch. Giving the mixing plant the neces-
sary versatility, allowing our customer to
develop new products and explore the
use of new raw materials.
Promixon improved also the water circuit
in the cooling jacket, optimizing the flow
of coolant water in the double jacket
with a coil real and reducing by 30% the
cooling times. Finally, the software has
been customized to the specific request
of the customer with a S.C.A.D.A. (Su-
pervisory Control And data Acquisition)
solution interfaced with the customer
ERP system for data exchange, statistics,
traceability of production lots, cost eva-
luation and much more.
