Sikora measuring technology
COLMEC SpA, developer and
manufacturer of extrusion lines for
rubber and silicone, has recently
opened up a new technology centre
at its headquarters in Busto Arsizio,
Italy. The new centre allows for
internal technical tests as well as the
development of new projects in a fully
equipped production environment.
On an area of 3,000m2 there are in
total four extrusion lines with the latest
technologies as well as devices and
machinery for mixing of rubber and
silicone. In addition, there are several
innovative measuring and control devices
from Sikora integrated in the extrusion
lines that are used during production for
monitoring quality and cost reduction. In
a research area, specially equipped for
tests, customers have the possibility to
test these new technologies and devices.
The lines cover diverse application
areas. One extrusion line is used for
the production of rubber profiles with a
combined vulcanisation system (hot air/
molten salt curing system). An additional
line, with high-speed hot air curing, is
suitable for the production of rubber
and/or silicone profiles. There is a third
extrusion line available for silicone cable
sheathing. In this line Sikora’s 3-axis
diameter gauge head, 3-axis lump
detector, spark tester as well as the
Centreview 8025 for the measurement
of the wall thickness, eccentricity,
diameter and ovality assure the highest
product quality.
The fourth line is a testing line for the
production and vulcanisation of rubber
hoses, in particular for the automotive
sector. Especially, radiator hoses are
manufactured at this line. Due to the
specific demands on the hoses, quality
has to be assured during extrusion.
For this reason, measuring and control
technologies that continuously monitor
and control product parameters are
directly installed in the line.
