Five companies partner
for in-mold medical project

In-mold labeling has become
widely adopted in consumer
plastic packaging applications.
In June 2023 however, a toolmaker
and automation specialist
met at the Technology Days
open house at injection molding
machinery
producer
Arburg
GmbH + Co. KG and started
thinking about which type of
advanced and innovative molding
technology they could develop
together.
A precise label application is
essential, since the label has
to show the exact amount of
substances placed in the 15
milliliter tubes.

of polypropylene pharmaceutical
analysis tubes, resulting
in a line running on the
Arburg booth at Fakuma 2023,
developed in close cooperation
between fi ve companies.

the line was running based on

seconds cycle time, including
" print-to-cut " label alignment
to tolerance of 0.2 mm by fi rst

plates, with the associated label

Sesotec lets users to take full
control of regrind purity, quality
By Beatriz Santos

The 2023 edition of Fakuma opened its
doors to the world premiere of Sesotec
GmbH's new sorting platform, Pre-Sort.
Sesotec says the platform promises to
redefi ne precision, effi ciency
and sustainability in the plastics
recycling industry.
The Schönberg, Germany-based
company has been
manufacturing recycling sorting
systems for more than 40 years.
It wants to leverage intelligent
technology for an effective and
profi table circular economy and
has bet on combing the components of its
Varisort Compact sorter, dedusting, material
conveying, and central control into one platform
to achieve just that.
The Pre-Sort platform is designed to give
users full control over the quality and purity
of input material, minimizing dependency
on external suppliers.

form can be seen hard at work. Mixed
material fl ows are extracted from a bin,
although silos, bags or octabins can also
be used. The selection of sorting levels
is done using preconfi gured modes, with
input material being assigned to three
exemplary classes. Class one is for nearly
homogenous input material,
with low level of impurities, for
example 90 percent good material,
10 percent foreign matter.
This is the chosen class for the

foreign, regrinds.
Class two is for heterogenous
input material, with medium to
high degree of contamination, with 65 percent
good material, 35 percent foreign matter.
Finally, class three is for heterogenous
input material, with a mixture of colors.
Once the input material is assigned to
one of the three classes, it goes through
dedusting. A counterfl ow classifi er system
reliably separates dust and fi ne
