needs in your daily production routine.
I am very proud of the fact that we consistently succeed in achieving the ambitious
targets set by our customers. Extrusion systems for profiles and sheets that meet
the most exacting standards in terms of quality and appearance despite increased
proportions of natural fillers (such as rice husks and wood flour) are only one
example. Another worth highlighting in this context is that of our pipe extrusion
heads for the production of plastics pipes, composed of up to seven layers, in a single cycle. This solution has been developed in response to the industryʼs demand
for ever-more sophisticated pipe designs. And, last but not least, our microwave
channel that vulcanizes rubber sealing profiles with closed hot-air circulation for
maximum energy savings is certainly worthy of mention.
We are highly dedicated to enhancing cost effectiveness and maximizing application efficiency in order to hone your competitive edge. The newly developed ZE
BluePower twin-screw extruder series clearly demonstrates this commitment. It

REVOLUTION IN COMPOUNDING:
THE ZE BLUEPOWER SERIES
ZE BluePower is a future-proof twin-screw extruder series with numerous innovative features.
Major highlights are a Do/Di ratio of 1.65 and a torque density of 16.0 Nm/cm3. Moreover, the
hydraulic screw preloading system, oval liners for high wear protection, improved side feeders,
degassing systems and energy management tool provide substantial benefits.

he outstanding performance profile of the ZE BluePower will
satisfy the ever-more challenging demands of processors in
terms of energy efficiency, cost effectiveness, easy handling,
ease of maintenance and operational reliability on a long-term
basis,” proclaims Dr. Thomas Winkelmann, Head of Plastics
Technology Development at KraussMaffei Berstorff, adding, “An optimum compounder rating additionally involves numerous features that
contribute to high cost effectiveness combined with energy-efficient
operation and excellent reliability.”
T
Increasing the output rate is one way of achieving enhanced cost effectiveness in plastics compounding on co-rotating twin-screw extruders, provided neither quality consistency nor process reliability are
affected. However, the output rate can only be increased up to a certain
maximum value as either torque or volume will reach its limits. Both
factors are inversely related to each other in engineering terms. Extruders with a relatively small outside/inside screw diameter ratio (Do/
Di) can be designed for high torques, but then have a small free volume.
Extruders with a higher Do/Di ratio offer greater free volume but lower
installed torques.
“In the last few years, all manufacturers of co-rotating twin-screw extruders have continuously optimized their compounding systems to
meet the growing market demand for higher output rates,” reports
Gerhard Scheel, Development Engineer at KraussMaffei Berstorff.
“This is why extruders of identical size have been equipped with drive
units rated for higher speeds and torques or why screw geometries
with a larger free volume have been selected.” KraussMaffei Berstorff
GmbH has adopted a similar approach and has continuously improved
its extruder series over recent decades by increasing the Md/a3 torque
density, which is defined by the ratio between screw torque Md and
center-to-center distance “a”.
New development instead of adaptations
The ZE BluePower series impresses with increased torque density
combined with an enlarged volume. Compared with the previous generation of extruders of identical size, the KraussMaffei Berstorff engineers have increased the torque density by over 30 percent for
torque-limited processes and the volume by more than 23 percent for
volume-limited applications in order to enhance the output rate.
Test results confirm simulation
In the development of the new extruder series, KraussMaffei Berstorff
used various simulation and calculation methods to determine an initial
optimum Do/Di ratio. The specific free volume and the torque density
were calculated as a function of the diameter ratio for the most commonly used range. Company engineers then verified the calculated results in various practical tests.
Both the theoretical calculations and the trials revealed that the best
results are achieved at a Do/Di ratio of 1.65 and a torque density of
16.0 Nm/cm3. So the characteristic features of the new series have
been determined on the basis of computer simulation and field tests.
The result of all these efforts is the new ZE BluePower series, which
is currently available with screw diameters of 42, 52, 65, and 80 mm. It
will replace the well-known ZE-UTX twin-screw extruder series in the
medium term.
Preloading system offers increased operational reliability
Powerful drive units, high-resistance screw shaft materials, and optimum tooth profiles at the screw shafts are indispensable for the
safe transmission of the high torques to the screws. In addition,
KraussMaffei Berstorff has developed a preloading system that ensures reproducible screw installation and preloading. This system subjects the screw shafts to a defined tensile stress only, without exerting
any torsion load.
To define the hydraulic pressures, the geometrical lengths and sizes
were rated on the basis of a cold screw considering the material characteristics and the resulting expansion coefficient. The machine operator simply selects the appropriate pressure specified in the machine
documentation and clamps the extracted screw in the preloading system. At the push of a button, the combination composed of screw shaft,
screw element and screw tip is safely preloaded in the elastic range
and in this state can be easily inserted into the processing section.

Cover story
Owing to their well-conceived series concept, all extruder sizes in the
ZE BluePower and ZE-UTX series can be preloaded with just three preloading systems. The defined preloading forces prevent the melt from
penetrating between the screw element and the shaft and thus help to
avoid time- and cost-consuming dismantling and cleaning operations.
All components put to the test
The development of a future-proof machine generation saw all technical components of the twin-screw extruder being put to the test.
Whereas proven features have remained unchanged, numerous elements have been modified and optimized. As with the preceding series,
the new twin-screw extruder generation still comprises the 4D or 6D
long barrel elements. The rectangular shape of the housing elements –
which are easily fixed and loosened by means of a clamping ring connection – has not been changed either. This ensures a pressure-tight
connection up to 350 bar.
AHEAD Issue 02.2014
The new ZE BluePower generation also comprises a modular range of
screw elements and supplementary equipment. One special highlight
is the enlarged feed opening on the side feeder – satisfying the general
trend toward higher filling levels. The option for easy conversion of the
side feeder into a side degassing system is also a novelty. Each extruder
includes a control unit that can be equipped with an optional energy
management tool designed to display all consumers on the screen.
Oval liners as a unique selling point
In addition to the hydraulic screw preloading system, the new elliptical
wear protection liners in the barrel count among the unique features
of the new extruder generation. These optional liners are an ideal and
cost-effective solution for wear-intensive compounding processes. If
required, only the liner – and not the entire barrel – has to be replaced. The new elliptical shape of the liners ensures a minimum distance to the cooling bores and cartridge heater bores, provided the

EDELWEISS DAYS
On the occasion of
the “Edelweiss Days,”
the line was used to
process post-industrial
film scrap with different degrees of
contamination.
About 60 representatives from plastics recycling and compounding
companies around the globe participated in the “Edelweiss Days”
on the KraussMaffei Berstorff premises in Hanover from June 24
to June 26, 2014. On this occasion, they were able to witness a live
demonstration of how HDPE and LDPE film scraps with different degrees of contamination are converted into high-quality compounds.
Plastics recycling helps to save natural resources
The new “Edelweiss” extrusion and recycling process was presented in production mode for the first time. Conversion of reclaim
material into high-quality compounds in a single heat is the main
benefit of this trendsetting solution. Thanks to the integrated process, repeated heating of the starting materials is not required. This
saves energy and minimizes the shear stress affecting the polymer
structure.
During the demonstration, the line was used to process HDPE and
LDPE post-industrial film scrap with different degrees of contamination to create a PE compound with a 70 percent calcium carbonate
loading. Used for this application, the line achieves an output rate
of 1,000 kg/h.
Customized solutions
Visitors to the event benefited from this unique opportunity to discuss in detail the innovative technology and the extensive service offers with the experts from Artec, Ettlinger, Nordson Kreyenborg and
KraussMaffei Berstorff. “The numerous personal discussions with
our customers have provided us with in-depth knowledge about their
individual requirements and expectations. This enables us to tailor the
optimum solution to any specific application,” explains Ralf J. Dahl,
pleased with the positive feedback the “Edelweiss Days” received.

The extruder is designed to produce complex compounds that contain high mineral filler proportions, for instance, and require excellent mixing efficiency. With its characteristic configuration, this
machine is an ideal complement to SKZʼs existing technical equipment. As virtually all compounding concepts are now available at
one location, this will allow SKZ to strengthen its leading position
in the field of plastics compounding yet further. Interested companies in this sector can use the equipment for tests and materials
development.
Flexible laboratory extruder
The KraussMaffei Berstorff ZE 25 UTXi laboratory extruder can be
equipped with a short processing section for different compounding
tasks. If needed for special applications, a longer processing section
configuration can be used and side feeders, degassing openings and
injection nozzles can be added. The high number of different barrel
and screw elements allows the machine to be tailored to very specific
process requirements.
Based in Würzburg, SKZ has been a competent partner to the plastics
industry for more than 50 years. About 270 staff members work in the

OPTIMIZED PROCESS ENGINEERING FEATURES OF TWIN-SCREW EXTRUDERS
TAILORED TO SHEAR- AND
TEMPERATURE-SENSITIVE WPCs
ZE co-rotating twin-screw extruders offer convincing engineering advantages – not only in
direct WPC profile extrusion, but also in the production of WPC compounds for two-stage extrusion processes. Apart from the modular screw and barrel system, KraussMaffei Berstorff
twin-screw extruders are characterized by various custom features that make them the ideal
solution for WPC processing.
TEXT: ANDREAS WESELER

“Owing to their favorable properties profile,
low price and high environmental compatibility, wood-plastic composites are being used
to an increasing extent for a wide variety of
products for indoor and outdoor applications.
Recent annual growth rates amount to about
25 percent,” reports Kai Schwedthelm, responsible for process engineering development in compounding and processing of bioplastics at KraussMaffei Berstorff. “WPC
decking profiles in particular are in real demand in Europe.”
process benefits are achieved by the 6D long
combined barrel elements, which are unique
on the market and a typical feature of ZE extruders. These elements allow the wood proportions to be efficiently incorporated and
the air trapped during the process to be removed at an adequate distance in process
engineering terms. For the degassing of residual moisture and volatile matter in particular, the degassing openings, 6D long,
ensure high process reliability at low gas velocities. The hold-down systems that are frequently needed to prevent the melt from rising in the degassing opening are not required
with this configuration.
When producing WPC products, however,
the special processing characteristics of this
material must be taken into consideration.
On the one hand, optimum dispersion of the
wood and plastic components must be ensured. On the other, the material needs to be
treated gently and must be plasticized at relatively low shear loads and low temperatures
in order not to affect the wood component.
Technical features for process optimization
In view of their specific process technology,
co-rotating twin-screw extruders of the ZE
series have firmly established themselves in
WPC processing. Recent technical improvements have been made to meet the specific
material requirements to an even greater extent. The plasticizing zone, for instance, has
been adapted along the processing section.
Through an innovative combination of kneading and multi-process elements, the melt
temperature can be reduced by about 10 percent while the melting efficiency remains
identical with that of standard screws. In addition, the KraussMaffei Berstorff engineers

The extruder is equipped with a ZSFE side
feeder based on Ultra Feed technology – a
special vacuum technology that gives higher
output rates through increases in the apparent density of light filler materials. With this
side feeder design, the total output rate in
WPC processing can be increased by a factor of 2.5 compared with conventional lines.
Finally, the screw geometry in the mixing
zone has been optimized, too. Here again,

have succeeded in improving the fiber feed
area. Here again, a well-tuned screw configuration gives optimum results. Further
Kai Schwedthelm sums up the benefits of
this tailored solution for us: “Together, all
optimizations ensure low-shear WPC processing at adequate temperatures. This
gives higher total output rates and products
with identical or even slightly improved mechanical properties.”

KRAUSSMAFFEI BERSTORFF SYNERGIES HONE COMPETITIVE EDGE
WPC DECKING PROFILES: TWO-STAGE EXTRUSION FOR ENHANCED COST EFFECTIVENESS
Direct extrusion processes that combine compounding and shaping into a single production cycle offer
clear benefits: the material is exposed to mechanical/thermal stresses only once, which gives the final
product improved physical properties and reduced energy consumption. This is true for many applications, but does not apply in general. In the extrusion of wood-plastic composite decking profiles, twostage processes provide substantially higher cost-effectiveness.

downstream equipment. Using three ZE 60 R x 46 D UTXi twinscrew extruders with an output rate of 350 kg/h for the planks
and a ZE 50 R x 46 D UTXi twin-screw extruder to produce the substructure profiles and edging strips, a highly efficient output rate of
1,200 kg/h is reached. The capital expenditure required for the singlestage line is about €3.47 million. According to KraussMaffei Berstorff
calculations, the annual energy costs amount to approx. €123,000.
WPC DECKING PROFILES
WPC decking profiles produced on a counter-rotating
twin-screw extruder.
WPC decking profile systems consist of the plank profiles for the substructure and edging strips. They are available in various colors and
with different profiles. The single-stage production process comprises
all steps involved starting with compounding, then shaping and finally
cutting to size on a single line. The core component of such a line is a
co-rotating twin-screw extruder. The benefits of this line concept are
low energy consumption, the minor thermal loads on the material and
the fact that the material is melted only once.
A cost comparison with a two-stage process was performed on the
basis of four complete compounding lines including upstream and
Two extrusion steps to a WPC decking system
In the cost-comparison example, the decking is produced on counterrotating twin-screw extruders with a performance of 350 kg/h in the
conventional two-stage manufacturing process. Three KMD 114-32/
WPC extrusion lines are usually employed for decking planks with different colors and profiles. A KMD 75-32/WPC extruder with an output
rate of 150 kg/h generally produces the two smaller profiles. A highperformance compounding line with a ZE 90 R x 48 D UTi twin-screw
extruder rated for 1,200 kg/h is used for compounding the WPC material. The investment costs for the complete line configuration amount
to approx. €3.08 million, the calculated annual energy consumption is
€214,200.
Comparing both process variants used in this sector reveals the clear
benefit of the two-stage extrusion process. Although direct extrusion
leads to annual power cost-savings of about €91,000, the amount invested is about €390,000 higher. This means that amortization of investment costs by power cost-savings will take at least four years.
Two-stage extrusion offers the additional benefits of higher flexibility
in terms of color and compound changes or the use of the WPC pellets
produced on the twin-screw extruder. And last but not least – compound and profile producers who already own some of the equipment
only need to purchase a few additional machines in order to enter into
the promising WPC profile market.

ustomers benefit from a successful mixture of the newest
software components and proven functional features, developed with current market demands clearly in view. As
you will see, the focus lies in the optimization of operating
convenience and the scalability of function.
A
Integration of new, innovative components
The development of the new C6 control system began with the implementation of new hardware and software components to build upon
state-of-the-art PC technology (such as the dual-core processor, SSD,
USB 3.0). In this way, the processor enjoys all the advantages of a secure, high-performance program platform (Windows 7, .NET Framework 4.0). The core functions of the previous, advanced C5 control system will continue to be used. Where necessary, limits were broken
and structures were modified to achieve more security and expandability in the software. With this new generation, KraussMaffei Berstorff also managed to combine state-of-the-art and innovative operating concepts using the proven and simple operating philosophy of the
C5. The C6 version is a state-of-the-art, flexible control system with
a solid, tried-and-tested functional basis. A large, capacitive 24-inch
16:9 full HD touchscreen (also available as a 21-inch model) provides a
clear picture and intuitive operation. The multi-touch capable display
is more sensitive and robust than on the C5 model, and features a flat,
edgeless surface.
The touch function simplifies operation in many positions. The machine buttons are now integrated into the user interface, allowing
them to be hidden or moved to other positions. Various button colors
display current statuses clearly and understandably; button symbols
are now automatically administered. An additional substantial advantage it is no longer necessary to replace symbol strips during retrofitting. In addition, the developers completely redesigned the layout of the screen pages. There is now a distinct separation between

parameter screens, which the machine operator requires, and setting screens, which are used for servicing and setting up the system.
Now, the user can use the settings dialog to quickly, and easily switch
between both operating worlds. The result is a clearly structured,
function-oriented screen layout and a noticeably reduced number of
screens without limiting functionality.
Several new operating elements support the user in operating the extrusion system. In addition to the sof tkeys, there is now a second level
for screen switching in the form of tabs. Multi-touch gestures, such
as rotating and zooming, can be used where appropriate without impairing reliability or accuracy. Of course, the screen division was also
developed further. The motto here is plenty of information, shown in a
compact and understandable manner, without excess. The new, userconfigurable cockpit pages are an excellent example of this. On these
pages, the processor can select the important parameters and display the sequences of its production conditions in graphical form – via
a trend diagram, for example (either analog or digital).
Even more uses for the processor
Ultimately, it is the new features and additions that set apart the C6
generation from the previous control system and from the competition. With this new generation, up to seven extruders can now be directly controlled. If multiple extruders are combined into one machine
(such as a main extruder and three co-extruders), almost any system
complexity can be displayed. The diagnostic functions have been further expanded to guarantee the fastest-possible assistance in case of
service. In addition to the passwords, non-contact chip cards (RFID)
can now also be used for access management via operating levels.
E-value curves provide the operator with valuable support for optimizing the production process in terms of energy and thus ensuring
low-wear use of the extruder. Listed actual values are now retrievable
for up to seven days.
OPTIONAL VERSION
Freely movable variants.
Proven technology implemented correctly
In keeping with the motto “One control system – everything in hand,”
proven elements were retained. Of course, the C6 control system
completely monitors and controls the entire extrusion system, and
does so from a single position. The strict separation of the visualization system and sequence control system has also proven to be useful.
KraussMaffei Berstorff implements separate hardware components
for this purpose. Therefore, an error on the PC or the control panel
does not necessarily lead to a system stop.
Upgrading made easy
Everyone familiar with the C5 control system will be impressed by the
new C6 generation. Each system equipped with the C5 control system
can be upgraded to the C6 version with minimal effort. Essentially,
only the main components of the control system (the PC, the PLC
and the control panel) need to be replaced. Furthermore, Berstorff
continues to guarantee uninterrupted, ongoing support and a supply
of spare parts for the C5 control system on existing machines and
systems.

and finally, a thin PE outer layer. The extruded
product is of the highest quality. This design –
consisting of a combination of an axial, three
radial and a conical spiral distributor, which
are optimally implemented according to their
functions – provides a number of advantages
related to process technology. The axial spiral ensures low pressure consumption in the
KraussMaffei Berstorff
inner layer (pressure loss) and high throughputs with a uniform wall thickness spread of
the thicker inner layer. The proven KraussMaffei Berstorff central feed concept makes
the system flexible during both normal use
and modifications. The radial spiral with a
lower throughput is ideal for the production of bonding agent layers and barrier layers. It guarantees an optimum wall thickness
spread, is easy to clean thanks to the low residence time and is space-saving.
Processes & products
from PE-RT at a speed of more than 40 m/
min. with a total output of 270 kg/h; and all
this with a minimum layer thickness of 50 μm
for bonding agent and EVOH layers.
This model is specifically designed for producing the following pipe dimensions:
• PE-RT: 8 – 32 mm
• PE-Xb: 8 – 40 mm
• PE-Xc: 8 – 40 mm
The conical distributor applies the PO outer
layer and, as a combination of axial and radial, ideally combines the advantages of
both. It offers high throughputs in a compact
design.
Typical market applications
With this sophisticated system, high-quality pipes with smaller diameters are typically produced for household water installations
such as hot water applications or for floor
heating systems with high line speeds, which
also contributes to the cost efficiency of the
processing industry. As an example, a complete system, equipped with a KME 45-36
B/R single-screw extruder as the main extruder and the KM 5L-RKW 01-40 pipe head,
can produce dimensions of 20 mm x 2.0 mm
system from a single position – in keeping
with the motto: “One control system – everything in hand.” In addition to fast and secure
access management, the C6 control system
provides the operator of complex systems
with the highest flexibility. This enables parameter pages to be combined and display and parameter texts to be individually
adapted. In addition, individual system components can be activated or switched off if
necessary.
Space-saving coextrusion solutions –
for the highest product quality
KraussMaffei Berstorff coextrusion concepts feature an extremely space-saving
machine arrangement. The intelligent piggyback version requires only a little more
space to manufacture five-layer pipes than a
system that produces monopipes.
Processors benefit from the great flexibility that enables them to produce even threelayer pipes with little adaptation effort as
well as many other excellent advantages: the
melt flow is optimally arranged through the
multi-dimensional, computer-supported design of the spiral geometry and melt channels. This enables processors to create a
finished product of the highest quality that
features optimum wall thickness with the
lowest tolerances.
This greatly reduces the effort required for
obtaining costly raw materials, particularly bonding agent and barrier materials. As
a result, cost effectiveness increases. This
KraussMaffei Berstorff concept also enables the processor to reduce changeover
and cleaning times to a minimum. Valuable
production time is saved, allowing the processor to manufacture smaller series. This
is an enormous competitive advantage because it enables the processor to respond
to market demands flexibly. The system
also provides an extremely flexible infeed,
which enables an individual, customer-specific system setup.

The KME 30-30 B/R coextruder, with an output of up to 50 kg/h and which was introduced
for the first time at K 2013, rounds out the
product line for our coextruders series with
moderate to low output ranges. In combination with the spiral distributor concept, it ensures excellent product quality. The grooved
bush integrated into the extruder provides consistent throughput independent of
counter pressure. In addition, the coextruder
guarantees an excellent blending capacity at
a high plastification capacity. The advantages
for the processor are plain to see: Excellent
thermal homogeneity, the best melt quality,
the perfect finished product.

C6 control system for perfect regulation,
monitoring and control
An additional unique selling proposition on
the market is the integration and monitoring of the system via the C6 control system.
This system allows the coextruders integrated into one system to be controlled and
regulated via the main extruder (maximum
of seven extruders); almost all system complexities can be mapped. The control system
monitors, regulates and controls the entire
Spiral distributor concept for a
seven-layer pipe head
In addition to the five-layer concept,
KraussMaffei Berstorff has expanded its
product portfolio since K 2013 to include
the series for manufacturing seven-layer
pipes. These pipes can be, for example, constructed from a three-layer inner pipe made
of two layers of PP-R and one layer of PP-R
with glass fiber. Similar to the five-layer
pipe, the bonding agent positions, oxygen
barriers, the bonding agent again and finally, the outer layer, are made of PP-R. Here,
we have also placed emphasis on a modular
design consisting of two to seven radial distributors with various spiral inflows. In addition to all the advantages, it is also worth
mentioning that the system – much like the
five-layer design – is optimally engineered
for saving space, in spite of the extensive
system arrangement.

hough regions such as Europe
and America have experienced a
significant upswing in traditional
PVC sheet extrusion, mechanical
engineering companies sense a
strong trend towards the processing of alternative materials, particularly those from renewable resources. The Resysta compound
already fulfills the technical and ecological
demands of tomorrow. The fiber-reinforced
hybrid material primarily consists of rice
husks, an agricultural raw material that had
been rarely used until now, combined with a
PVC substrate. This construction makes the
material environmentally friendly and highly resistant to weathering. It features excellent environmental performance, setting new
standards for sustainable production.

perform Resysta processing is high-quality wear resistance. Therefore, the screws
at KraussMaffei Berstorff are exceptionally
thoroughly armored to be highly wear-resistant, and the barrels must be similarly protected. This combination ensures maximum
protection of the processing unit against corrosive and adhesive wear during processing
of the Resysta compound.
Successful live demonstration for more
than 60 interested customers
A recent live demonstration at KraussMaffei
Berstorff attests to the large amount of interest surrounding this innovative product. Andreas Kessler, General Sales Manager at the

ECOLINE
EcoLine microwave channel gives minimized energy
consumption thanks to low waste gas losses and
energy-optimized switched-mode power supplies.
IMPROVED COST EFFECTIVENESS AND ENERGY SAVINGS
ECOLINE MICROWAVE CHANNELS MAKE
TRELLEBORG FIT FOR THE FUTURE
At the beginning of May, Trelleborg AB, a Swedish producer of sealing profiles for the automotive and building industries, started to operate two EcoLine microwave channels, which had been
ordered from KraussMaffei Berstorff during K 2013 in Düsseldorf.
TEXT: ANDREAS WESELER
PHOTO: KRAUSSMAFFEI BERSTORFF
Good things take time – particularly true
when it comes to well-founded investment
decisions geared toward sustainability. After
having convinced themselves of the pioneering benefits of the EcoLine profile production
line during the Technology Day, held at the
KraussMaffei Berstorff premises in Hanover
last summer, Trelleborg signed the purchase
contract at K 2013.
Explaining the company’s investment decision, Trelleborg’s Purchasing Manager
Joakim Hansson says, “In view of the excellent
results in terms of productivity and quality obtained during extensive tests, we decided to
opt for two lines to increase our vulcanization
productivity further.”
“The special features of the EcoLine microwave channel are reduced waste gas losses and the energy-optimized switched-mode
power supplies,” explains Helmut Lüders,
Product Manager for Rubber Profile Production Lines at KraussMaffei Berstorff. Mr.
Lüders also praised the closed air circulation, which provides maximum cost-savings
as 90 percent of the energy-intensive process air remains in the system, and the other
new feature – the improved thermal insulation to the process chambers.
Time-tested technology for
maximum reliability
Each of the four microwave channel modules
is equipped with one generator with 6 kW of
magnetron power. A circulator integrated
into the energy supply transfers the energy
not absorbed by the product to the connected
water load, thus improving the magnetron’s
service life. The channel has a total installed
magnetron power of 24 kW.
The microwave generators are arranged
above and below the conveyor belt. The
specific design of the microwave coupling
system ensures an extremely homogeneous
field distribution. Both the microwave power
and the conveyor belt speed can be continuously adjusted. The microwave channel has
an effective cross-section 280 mm wide and
150 mm high.
The central control panel ensures that system settings can be selected with maximum
ease. And the innovative process-oriented
user interface helps to reduce set-up times
during changes of material. Trelleborg intends to use the new microwave channels to
reduce operating costs in vulcanization and
hone the company’s competitive edge. “The
EcoLine microwave channels are the ideal
solution for our specific requirements. This
well-tuned combination of time-tested technology plus technical innovations is a sound
investment in our future,” explains Joakim
Hansson.

PERSPECTIVES IN THE LAND OF
SAMBA AND SOCCER
Everyone is talking about the BRICS countries (Brazil, Russia, India, China and South Africa) as growth markets, and they are also strategic target areas for the KraussMaffei Group. With its 30 employees, the sales
and service subsidiary in Cotia, São Paulo, is gaining special significance as a support point for all activities
in South America. The head of this subsidiary, Klaus Jell, provided AHEAD with an insight into the market.
TEXT: DR. SABINE KOB, CLAUDIA STADLER
PHOTO: SHUTTERSTOCK
IMPORTANT MARKET WITH A
PROMISING FUTURE
Brazil is more than samba and soccer: The South
American country is the most important market in
South America for the KraussMaffei Group.
Some 3.5 million vehicles per year make the host of the World Cup in
2014 the seventh-largest manufacturer of automobiles now, and by
2020 this number should rise to 4.5 million. The VW Golf has been the
best-selling vehicle for a long time, and the premium brands BMW
and Audi are also currently erecting plants where best-selling models like the Series 1 and 3 or the A3 will be developed in the future. For
injection molding and reaction technology applications from KraussMaffei, the focal point of sales is the automotive industry, but the requirements here often differ from those in Europe. While high-tech
solutions such as processing of carbon fibers can be marketed here
in Europe, the automotive sector in Brazil is extremely price-driven.
As the standard of living rises, however, standards are also growing,
for example, for the design of surfaces, and even more complex production plants will be required. Then the competitive edge of expertise
from the collaboration with OEMs and suppliers is of great benefit.
Opportunities for growth in the consumer goods
and medical industry
In addition to cars, which are classified as durable goods, the consumer sector in South America also offers many opportunities; foremost here are the beverage, packaging and medical industries. The
KraussMaffei Group has tried-and-tested
clean-room concepts of the KraussMaffei
and Netstal brands with high output quantities, for example, for blood-drawing tubes
and cannulas for injections. Future development is being ranked in the same way as the
high demand in China, where the production
location in Haiyan has opened its doors for
its own showroom. This is because the ever-more mobile lifestyle around the globe
coupled with higher purchasing power is leading to the demand for
packaging for water and carbonated soft drinks. In South America,
the market for filled and packaged beverages amounts to an estimated 160 billion liters – and market researchers predict annual growth
of four percent by 2016.
Constant demand from the construction industry
Activity in the field of extrusion is benefiting from the continuous population growth in Brazil, a country with 200 million inhabitants and a
growing need for infrastructure for building construction and underground construction. At the same time, the production of PVC pipes
for transporting drinking water or for drainage has a long tradition
there, and the KraussMaffei Berstorff brand is established among
all large pipe manufacturers. Of course, the country also poses challenges – such as pronounced bureaucracy, unequal education opportunities and infrastructure that needs improvement. Nevertheless,
Brazil is the most important market in South America for the KraussMaffei Group. Klaus Jell emphasizes, “We are glad that European and
American customers are settling here, which results in the level of
quality rising even more. We want to use the opportunities in growing
business units such as medical technology for the long term.”

SWISS SYSTEM EXPERTISE FOR THE WORLD
NETSTAL MEANS SUPPORT FROM A TO Z
The path from a customerʼs idea for a product up to the complete production line is often shorter and
more efficient than one thinks – if the customer makes use of the expertise and experience of Netstal
as a general contractor and system integrator.
Netstal not only builds high-tech injection molding
machines, but also provides turnkey systems that
have all the system parts integrated. Their scope
extends from material processing and feeding, to
the injection molding process with subsequent quality inspection, all
the way to packaging of the finished product and the hall layout.
Thanks to the close cooperation of Netstal with the suppliers of
molds, automation or logistics, all elements are perfectly coordinated from the outset. The customer does not lose any time with either
rough or fine tuning of the system. To the extent necessary, all of that
is already done at Netstal. Before delivery, the entire line is set up in
Näfels, commissioned and released.
This is followed by function, quality and performance tests in real
operation, and finally by training of the customer at his or her plant.
But cooperation does not end with the delivery. Extensive after-sales
