for this application. Compared
to classic injection molding, this
process requires signifi cantly less
injection pressure. "
As for the Next Cycle IML-brand
label, it is printed with nonbleeding
inks on a PP label that can be
completely separated from the PP
of the cup during recycling. This
keeps apart printed label fl akes
from container fl akes.
contrast with thermoforming, no
pre-produced foils are used and
no stamping waste is produced.
Dolphins from
A production cell featuring an
Allrounder 470 E press and a Yaskawa
six-axis robot will process
post-consumer recyclate in the
form of old fi shing nets into dolphin
fi gurines. The dolphins are
made from material based on high
density polyethylene in the electric
press with a clamping force of
1,000 kN and a 1+1-cavity mold in
a cycle time of about 30 seconds.
The two curved upper and lower
shells of the dolphin are removed
by the robot.
The parts are then welded using
ultrasound. Arburg's partner,
Herrmann Ultraschalltechnik,
developed a special sonotrode
contour for the sophisticated 3D
geometries to ensure that both
halves fi t together exactly. The
technology selects the right gating
point to reduce shrinkage and
distortion for repeatability.
In the next step, the dolphin
gets a face in a multicolor printing
system from partner ITW Morlock.
The surface is pre-treated so
that the ink adheres well. The fi nished
product then is deposited
on a conveyor belt.
Industrial 3D printing
Arburg is out with a new
high-temperature version of its
recently released Freeformer
750-3X, which will process Ultem
9085 plastic granules - an aerospace-approved
material - into
ventilation ducts with complex
geometries. To achieve this, the
temperature of the build chamber
can be raised to 200° C for the
granules, which are plasticized at
up to 450° C.
The machine has three discharge
units and a large part carrier
especially suitable for the
medical, automotive and aerospace
Arburg offi cials said the compact
3D printers in the TiQ series
provide a good entry level for processors
to begin additive manufacturing
because they have open
material systems.
At Fakuma, a TiQ2 will process
fi ber-reinforced fi laments based
on PA and PP into suction pads
and mechanical grippers to be
mounted on robot arms with individualized
fi ngers for picking up
Two-component parts
Arburg offi cials said they have
a clever way for injection molding
two-components parts cost-effectively
with the Allrounder More
machine series, which is available
with a horizontal and vertical injection
unit as standard.
The two injection units are easily
accessible, which makes it easier
to maintain and incorporate
peripheral equipment, such as a
mixing unit or coloring device.
At Fakuma, an Allrounder More
2000 with a 2,000 kN clamping
force and with two electric injection
units in sizes 200 and 400 will
produce a two-component box
made of thermoplastic (PBT with
30 percent glass bead content)
and self-adhesive liquid silicone.
The two components are injected
directly via a cold or hot runner
system for waste-free production.
A fl uorescent marker added
to the thermoplastic box, which
isn't identifi able by the end user,
allows products to be traced,
distinguished from counterfeits
and sorted by material with a laser
Digital fi ngerprints
Arburg also is demonstrating
how digitalization and automation
work together by producing
a bicycle tool with traceability.
The two-part tire levers, which
are used to remove bicycle tires
and inner tubes from the rim and
mount them again, incorporate
tracing technology by Detagto.
The levers are produced on an
Allrounder 375 V with a 1+1-cavity
family mold from glass-fi ber-reinforced
nylon 66/6 in a cycle time
of about 45 seconds.
A Kuka six-axis robot, which is
suspended to save fl oor space,
feeds parts for camera inspection
and inserts them into the
mold. The removed molded
parts then are given a barcode in
a laser station. The part-specifi c
data can be retrieved by scanning
the barcode.
Arburg is in the top 5 percent of
the world's most sustainable industrial
companies, according to
a rating platform for global supply
chains called Ecovadis.
The rating takes into account
the environmental impact, sustainable
procurement, and labor
and human rights of more than
100,000 companies.
Arburg earned 73 points, giving
it gold medal status despite more
stringent criteria in 2023.
The grassroots family business
supports regions, family and people
and adopted a brand promise
of " Wir sind da " ( " We are here for
you " ), said Gerhard Böhm, Arburg
managing director of sales
and after sales.
" This is something we don't
compromise on: We have a fi rm
commitment not only to technological
excellence but also to the
environment and the concerns of
all our stakeholders, " Böhm said.
For example, decades ago, company
offi cials decided to produce
centrally with short, fl exible and
transparent supply chains. Seventy-two
percent of supplies come
from Germany, and 66 percent of
them from Baden-Württemberg.
" Arburg uses quantifi able measures
to distance itself from greenwashing
and plans to be compliant
with the 1.5° C target in
scopes 1 and 2, " Böhm said.
" To achieve this, we will reA

density polyethylene,

duce our CO2 emissions in those
areas by 42 percent by 2030 compared
to 2021. For scope 3, we
are aiming for what is known as
a 'sub-2° C' target, where the reduction
in the same period is 25
percent, " he said.
Scope 1 includes all direct greenhouse
gas emissions, such as primary
energy sources consumed
in corporate real estate, while
scope 2 covers indirect emissions
resulting from the generation of
the procured energy. Scope 3 addresses
indirect emissions primarily
associated with the company's
activities, for example, due to purchased
The operation of injection
molding machines at customers'
sites is also accounted for
in scope 3. This is because the
operating phase of the machine
causes 95 percent of the CO2
emissions and thus represents
the greatest lever for reducing
these along the value chain.
Arburg's Action Plan: Energy
involves working with customers
on effi cient, sustainable production
processes in order to save
CO2 together.

Talent pipeline full
On Sept. 1, 104 new trainees
started their careers at Arburg,
and the talent pipeline remains
full. In all, 327 trainees and students
from the Baden-Württemberg
Cooperative State University
(DHBW) are currently taking
advantage of the opportunity to
train for positions with the machine
" Even and especially in economically
diffi cult times, we are
sticking to our high training quota
of around 10 percent, because
it will be our qualifi ed junior staff
who will continue to move our
company forward with their expertise, "
Managing Partner Renate
Keinath said.
The prospective employees
are a diverse group with some
trainees older than 30 and having
initial work experience and more
young women pursuing technical
training as mechatronics, machining
and electronics technicians.
Arburg has a 2,000-square-meter
vocational training center that
offers a comprehensive program
led by training manager Michael
Vieth and his staff of 20.
The family business continues
to train apprentices at a steady
pace and hires almost everyone
into permanent technical
and commercial positions every
year, such as industrial mechanic,
technical product designer,
plastics and rubber technologist,
or industrial clerk. The courses
cover industrial engineering,
computer science, mechatronics,
electrical engineering and
mechanical engineering.
Arburg works closely with vocational
schools and state universities
and became the fi rst company
in Baden-Württemberg to be
awarded triple certifi cation since
2018 for quality management in
training, learner-oriented quality
testing in further education and
the seal of approval of the Chamber
of Industry and Commerce.
Since Arburg's training programs
began in 1949, the company
has trained almost 2,300
young people who have chosen
from 12 training and eight DHBW
degree programs.
