Sumitomo Chemical launches
new Meguri brand
Meguri, the Japanese word for circularity, is
the name chosen by Sumitomo Chemical to
introduce its new range of products derived
from recycled feedstocks.
The Meguri brand comprises a wide
range of recycled plastic products, including
PMMA, polyethylene and polypropylene
produced by advanced recycling technologies.
The PMMA will be obtained from
a pilot facility for chemical recycling, which
is to be constructed at the Ehime Works in
Japan; the company is developing a facility
jointly with Sekisui Chemical to produce
polyethylene based on municipal waste.
The portfolio will also include polypropylene
compounds for automotive parts made
from recycled
used plastics.
Ac c or ding
to the company,
the Meguri
brand will
continue to
be expanded
and promoted,
through building
alliances with
customers, other companies in the industry,
local governments and other stakeholders
towards creating the infrastructure to help
develop a circular economy.
With the new brand, Sumitomo Chemical
aims to make a contribution towards reducing
environmental impact. The company said that
'efforts towards a circular economy for plastic
resources' are one of the material issues to be
addressed as management priorities.
Equipment
Clean and quiet granulators
CMG is introducing for a new series of
low-speed screen-less granulators highly
technical injection moulding. The new
product line produces outstanding regrind
quality and offers efficient operation, ease
of cleaning and good application flexibility.
The rotor cutters cut the parts to regrind
finely and precisely, rather than fracturing
or crushing the materials, producing the
most homogeneous regrind shape and dimensions,
without any dust.
The new SL range consists of four models,
in capacities ranging from 5 kg/h up to
30 kg/h.
A high intensity magnetic plate positioned
at the feeding point of the unit
serves as a metal trap to capture any metal
that could potentially contaminate the regrind
or damage the granulator or the injection
moulding machine. In addition, the
SL granulators are equipped with sound
insulated feeding hoppers, achieving noise

into an existing process and are perfectly
suited as a retrofit solution, e.g. for demanding
recycling applications. Other Gneuss
offerings at the show are its assortment of
available sensors that match regional or
application-specific requirements such as
Atex, Hart Communication or EAC and are
also available with digital IO-Link communication.
For special process conditions or
difficult places of installation, Gneuss offers
individual sensor solutions; new here
are the rotatable sensor shaft and a flange
mounting solution.
levels well below those industrially acceptable
(EN12012-1). All hoppers are equipped
with sight glass for visual inspection of the
grinding operations
The entire SL unit can be accessed,
cleaned and put back into operation in a matter
of minutes. All parts are accessible with no
need for tools and can be cleaned by vacuum.
Also, all SL models are designed to be accessible
from one side and do not require to
be moved away from the injection moulding
machine to perform maintenance or cleaning.
CMG provides technologies and solutions
designed for the recycling industry,
all certified for Industry 4.0 compliance. Its
solution will be on show at the upcoming
PRSE in Amsterdam.
Continuous filtration
Also at the PRSE, Gneuss will be showcasing
a compact MRSjump Extruder featuring
a high decontamination performance and
a viscosity boost in one single extrusion
step. The company is also introducing an
additional size across its line of Rotary Filtration
Systems. Its RSFgenius, SFXmagnus,
SFneos and CSFprimus models are now all
available in a size 110, filling the gap between
the the currently available size 90 and the
next size up, which was was the size 150.
Rotary Filtration Systems operate continuous,
automatic, process and pressure constant.
They are characterized by a filter disk
on which the screen cavities are located in
a ring pattern. Screens can be changed on
the part of the filter disk that is not active
in the melt channel, while the production
process continues to run without any interruptions
or disturbances. Gneuss Melt
Filtration Systems can be easily integrated
Control
system
Gestica control system
improved
Arburg's flagship Gestica injection moulding
machine control system has undergone
detailed improvements, mainly to the system's
navigation and the sequence editor,
The Gestica
monitor with
multi-touch
technology
so that machine operators save time and
reach their goal with just a few clicks. Multilift
and six-axis robotic systems can be
fully integrated into the system, retaining
the Gestica look and feel during operation,
making the cycles faster and more efficient
and improving reliability through the mutual
interlocking of functions. The range of
functions in the control system is far greater
than that of the previous Selogica system.
Among others, 'assistance functions' are
available that further increase ease of use
and efficiency
The control unit has two separate computers
for operation and process control,
including Multicore technology. As well as
operational reliability, this also provides the
best possible protection against unauthorised
external access. In addition, because
Gestica has a closed operating system, no
security updates are needed. Also, it is easy
to integrate printers, USB memory units
and browsers.
Gestica is also " digitally ready " . Thanks to
Gneuss Melt Filtration Systems are suitable as a
retrofit solution
its OPC UA-based connectivity, the control
system allows entire production cells to be
managed and enables simple communication
with higher-level systems.
