Arburg combines sustainability with
new technology for Fakuma 2023

Arburg is tackling issues to conserve
resources, reduce carbon
footprints and return recyclable
plastics to the circular economy
at Fakuma 2023.
With nine exhibits at Hall A3,
Booth 3101, plus 10 machines
on partner stands, the Lossburg,
Germany-based machine builder
addresses topics of sustainability,
digitalization and automation,
which company offi cials say must
go hand in hand to solve issues
related to plastic processing, including
the labor shortage.
" We will show our customers
how they can benefi t not only
from our products, solutions and
services, but also from our decades
of experience, " said Juliane
Hehl, managing partner of marketing
and business development.
The company continues to promote
its products and solutions
under the theme: " There is only a
Plan A. "
The 100-year history of the
company also will be presented in
a special exhibition area. The longevity
and success of the business
is further proof that environmental
protection and the responsible
use of resources are fi rmly rooted
in Arburg's DNA, Hehl added.
At its own facilities, Arburg
has taken many eco-driven steps
over the decades, incorporating
use of rainwater in 1997, wind
power in 2001 and geothermal
energy in 2009.
During a recent project by the
regional utility to bury power
lines, Arburg offi cials were able
to limit the costs of connecting
their wind turbines to their inhouse
power grid. The company
paid for a long cable connection
to feed its generated wind energy
to the grid.
Today, wind turbines supply
the company's electricity. Arburg
produces enough wind energy
to power the equivalent of 340
households.
" The cost of the power line to
the wind turbines will have paid
for itself in less than fi ve years, "
said Florian Schmitz, head of
building services, said of the project
completed in January 2023.
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.
Some of the highlights of Arburg's
exhibits at Fakuma follow:
Hybrid series grows
Arburg introduced the Allrounder
520 H with a 1,500 kN clamping
force as the latest machine in the
new hybrid Hidrive series that
launched in the spring with the
470 H machine unveiled to mark
the company's 100th anniversary
of Hehl family ownership. The Hidrive
series combines an electric
clamping unit designed for energy
effi ciency and precision with a
powerful hydraulic injection unit.
At Fakuma, an Allrounder 520H
" premium " will use a 1+1+1-cavity
mold to produce three different
ABS parts in a cycle time of
around 50 seconds. The parts
- a machine base, feed hopper
and controller - will then be
separated in a cutting station to
round off a set of 15 parts for a
model Allrounder, which will be
on a scale of 1:18.
The machines incorporate
valve technology (Varan) to split
the main pump's available fl ow
volume when required. This eliminates
the need for multipump
technology.
" This enables simultaneous
movements of hydraulic auxiliary
axes with programmable control,
such as the ejector and core
pull, without technology stages
or multipump technology, " an
Arburg news release said. " This
saves energy, costs and space on
the machine and increases production
effi ciency. "
In the demonstration, a Moldlife
Sense-brand computer system
enables sensor-controlled mold
monitoring over the complete life
cycle. The data is recorded, and
the control system displays malfunctions
and performance-dependent
information for predictive
maintenance.
A Multilift Select 8-brand linear
robotic system with an 8-kilogram
load removes the molded parts
and places them in a box.
The hybrid Hidrive series machines
cost less to purchase and
operate compared with all-electric
and hydraulic machines, and
they contribute to a reduced carbon
footprint, according to Arburg
offi cials.
For example, compared with
corresponding hydraulic machines,
the machine builder said
the energy footprint of the new
Allrounder H is up to 50 percent
better, while a new oil management
concept requires up to 35
percent less oil. Also, the required
cooling water capacity can be reduced
by up to 70 percent and
the dry cycle time drops about 40
percent, the release said.
Alternative to
thermoforming
Injection compression molding
can be an energy-effi cient alternative
to thermoforming as demonstrated
by an electric Allrounder
720 A " ultimate " machine that
produces thin-wall, in-mold label
cups that are recyclable. The machine,
which has a clamping force
of 290 tons and is equipped with a
size 1300 injection unit, can handle
very high injection volume
fl ows and injection speeds of up
to 400 millimeters per second.
In the demonstration,
a
four-cavity mold from Brink is
used to produce the round cups
made of polypropylene. The mold
is equipped with six sensors for
position measuring and embossing.
The four molded parts, which
each weigh 10.8 grams and have
a wall thickness of 0.37 millimeters,
are produced in a cycle time
of 3.95 seconds. A side-entry robot
from Brink inserts the labels,
removes the fi nished cups and
stacks them on a conveyor belt.
The combination of an all-electric
packaging machine and injection
compression molding
improves the energy footprint 20
percent while reducing the part
weight from 13 to 10.8 grams.
" Meanwhile, the fl owpath/
wall thickness ratio is 380:1, " a
news release said. " Normally, this
would require a very high level
of injection pressure - at the
expense of energy requirements
and mold wear. This is why injection
compression molding is used
