Sulzer Chemtech
Mixers for the Plastics Processing Industry
Welcome to the Global Market and Technology Leader
Sulzer Chemtech is the world‘s leading supplier of static mixers
and mixing systems. And for very good reason! We provide our
customers with innovative and tailored solutions, enabling them to
secure clear competitive advantage - as we have been doing for
more than 35 years!
Homogeneity leads to quality
In polymer processing, perfectly homo-
genized melt plays a decisive role in achiev-
ing high-quality end products. Faults such
as colour streaks, uneven wall-thickness
or low lines inevitably result in higher pro-
duction costs and higher rejection rates.
Continuous development of our products in close cooperation with customers helps us
to be always one step ahead. Research and development work of the highest standard,
backed up by tests and studies, own worldwide manufacturing facilities, excellent spe-
cialist advisory support and outstanding after-sales service - a sound basis for being able
to maintain our No. 1 position in the market.
This is where the static mixers from Sulzer
Chemtech come into their own. High mix-
ing eficiency in the shortest overall length,
low shear attributes, and a zero main-
tenance requirement, predestine these
mixers for wider use in the polymer pro-
cessing industry. Both in injection mould-
ing and extrusion processes, they ensure
the degree of homogenization neces-
sary to guarantee consistent high-quality
plastic end products. One thing is certain,
quality pays off. Take advantage of our
know-how to shape your success.

What is static mixing?
Static mixing is mixing without the use of moving parts. What does move are the com-
ponents to be mixed. In plastics processing, the components are propelled through the
mixer by means of pumps or screws. The mixing elements remain in a ixed position
and effect continuous split-off, expansion and redistribution of the melt low across the
full cross-section of the low path. The result is a fully homogeneous melt.
Sulzer Chemtech maintains a compre-
hensive range of mixers suitable for spe-
cial applications. Contact us for further
advice, and do not hesitate to ask about
possibilities for testing. Exploit the know-
how of the best in this ield!

Injection Moulding
Injection moulding - we identify solutions
Processing problems such as the formation of colour streaks are frequently solved by
modifying the process parameters. In cases involving self-colouring of products, this
approach is often only partially sucessful. Masterbatch concentration and screw back
pressure have to be increased in such cases, inevitably leading to a substantial inlation
of production costs.
Tackling the problem at the root
Through installation of a mixer, Sulzer Chemtech offers a simple but ingenious solu-
tion to completely rule out reoccurrence of such problems. In businesses aiming to
produce qualitatively high-grade plastic workpieces at reasonable cost, a static mixer
from Sulzer Chemtech quickly becomes an essential component of an injection mould-
ing process.
Our mixers assure you of a consistently homogeneous melt, a privilege guaranteed by
their patented geometry. The beneits are obvious: better quality of the formed work-
piece, reduced colorant consumption, fewer rejects, lower costs, greater return.

The most suitable product for each application
Sulzer Mixing Heads SMK-X and SMK-R
The Sulzer Mixing Head type SMK-X or SMK-R is itted directly
in the nozzle of the injection moulding machine. It incorporates
four to six mixing elements which serve to homogenize the melt
during the injection phase. Colour and temperature distribution
improve by a previously clearly predeined and exactly calculated
factor in relation to the number of mixing elements employed.
The SMK-R is a modular system, an assembly of mixing ele-
ments, a middle sleeve and end sleeves. In the case of the SMK-
X head, the mixing elements are brazed in a sleeve unit.
Applications
• Colouring of polymers
• Reduction of distortion problems
• Processing of recycled material (regrind)
Your beneits
• Reduced colorant costs of up to 30 %
• Improved cycle times
• Enhanced product quality
• Fewer rejects
• Short pay-back period
• Excellent self-cleaning properties
