focus is on demanding applications,
such as barrier
films or packaging with an
increased percentage of PIR/
PCR, the company said. Automation
and digital systems
for improving eff iciency, such
as the RUBY IoT- system will
also be highlighted, with live
demonstrations run on the
VAREX II blown film line on
the stand (hall 17, stand A57).
W&H is also inviting visitors
to the four-day EXPO at its
headquarters in Lengerich.
More than ten machines covering
extrusion, printing, and
converting will be running live
demonstrations several times
a day. Visitors can register at
the W&H booth at K to join.
KraussMaff ei (hall 15, stand
C15/C24-D24) will be showing
its DCIM (Direct Compounding
Injection Molding) system that
enables diff erent recycled materials,
with diff erent viscosities,
to be economically processed
- using a single-screw extruderinto
a homogeneous melt that
can subsequently be injected
moulded into products. At K,
five-piece polyolefin collapsible
crates will be produced from PP
staple fibre fleece from FFP2
masks, shredded HDPE from
logistics packaging goods and
HDPE blow moulding scraps
from toy production, with masterbatch,
stabilizer additives
and micaceous iron oxide added
as fillers.
The extruder, equipped with
a specially developed, elongated
screw with a ratio of length
to diameter of 30 L/D (instead
of the normal 17-23 L/D) is installed
in a space-saving piggyback
position directly over
the injection unit of a standard
hydraulic machine. The compounded
melt is conveyed into
the plasticising unit in a single
heating process, which reduces
degradation of the polymer,
conserves energy and reduces
the CO2 footprint. The extruder
and injection moulding machine
produce in intermittent
operation, which means that
when the injection volume
for the next cycle has been
reached, the extruder stops.
The system complements the

for cylinder induction heating,
which helps to significantly
reduce energy consumption
tremely accurate temperature
control thanks to reduced thermal
inertia. It will be on display
at the stand on a twin screw
extruder from the Nextmover
range, demonstrating that with
this technology, an overall productivity
of 2,000 kg/h can be
achieved for PVC pipe diameters
from 63 mm to 160 mm,
while saving 35% energy.

on Bausano's new single screw
extruder E-GO R, purpose-designed
for recycling highly
contaminated plastics, which
the company is debuting at K.
Bausano claims the E-GO R
can handle challenges such as
HDPE waste from containers
for milk, motor oil, shampoos
and conditioners, soap, detergents,
and bleach. Other applications
include PP waste from
lunch boxes, yoghurt pots, syrup
and medicine bottles, caps
and LDPE waste from cling film,
shopping bags, and squeezable
bottles.
company's well-known IMC
technology and, says KraussMaff
ei, enables material cost
savings of up to 50 percent.
Bausano (hall 16, stand B70),
specialised in the design and
production of customised
plastics extrusion lines will be
showcasing its Smart Energy
System for cylinder induction
heating, which helps to significantly
reduce energy consumption.
The system features
forced-cooled induction coils
with special openings that allow
air to pass through and
the temperature sensor to be
installed. The coil is wrapped
in highly insulating materials
to minimise heat loss from the
cylinder to the outside. The
cooling airflow is channelled
directly onto the plasticising
cylinder for faster cooling. The
system allows for an even heat
distribution and a lower coil

heating up to 250 °C and exThermoformed

Promix Solutions in hall 9,
stand E18 is presenting solutions
for the mixing, foaming
and cooling of polymer melts
that can save raw material
costs, reduce the carbon footprint
and increase production
capacity. Promix Microcell
Technology creates a microcellular
foam structure in the polymer
by adding environmentally
friendly atmospheric gases (N2
and CO2). This reduces the
product weight by 20 - 50 %,
yielding substantial savings in
raw materials.
Promix has spent the past
two years on the further development
of physical foam extrusion,
achieving an important
milestone in terms of cell size.
The company has successfully
halved the size of its foam cells
from 100 microns to, on average,
50 microns. The extremely
fine-celled structure yields
mechanical values comparable
to those of non-foamed trays
of the same thickness but with
weight savings of around 20%.
The technology is suitable for
use in packaging films, sheets,
foam core and corrugated
pipes as well as profiles, cable
sheathing, blow moulding and
blown films.
The technology can be used
