the cold end of the line, where
our three different machines
draw the tubes, cutting them
inside, cutting them in a pre-
liminary length and carrying
out the final cutting and glaz-
ing operations, in order to have
the finished tubes ready for
packaging.
The two processes used to
form the tubes are:
1. the Danner process: with
all its advantages in closely
respecting the physical dimen-
sions tolerances, in particular
diameter and thickness of the
tube, and therefore being the
perfect process for the pro-
duction of tubes for ampoules
and vials; and
2. the Vello process: more flex-
ible in terms of tube shapes
and dimensions (in particular
thickness), perfect for the pro-
duction of tubes for cartridges
or for syringes.
OGT Tubing Lines produce
tubes with diameters from 5 to
50 millimetres (normally for
pharma packing the maximum
diameter is up to 40 millimetres),
with various thicknesses, accord-
ing the different uses of the tube,
which range from 0.1 up to 1,5
and more.
Here below a 3D representation
of a typical layout of a tubes form-
ing plant, made up of a Melting
Furnace (up to 22-24 tons per
day) and two Tubing Lines, each
with the maximum capacity of
10.5-11 tons per day. �
