Extrusion is an ever-developing sector
whose figures increase year by year. This
sector processes about 40 percent of
plastic materials in almost all countries.

Among the solutions for extrusion world there are:
DISCOVERY 12T
: an innovative high-efficiency automatic mul-
tiflow cooling ring with thermal sectorial adjustment enabling
an exact and automatic thickness adjustment. The system dras-
tically reduces thickness tolerances along the whole circum-
ference balancing out melt flows. Discovery “gets its head to-
gether”, since it compensates possible misalignments through
a thermal modulations to obtain a constant bubble thickness
and save up to the 12 to 14 percent of raw material. Discovery
exploits two cooling flows to control material lengthening in
combination with the thermal factor.
EAGLE thickness control completes the equipment by constant-
ly reading the film gauge and drives the lengthening along the
whole circumference with less than one percent tolerance.
The NAVIGATOR 9000 supervises the integrated management
