engineering
division
The Arthur Habermann company
was founded in 1927 and is a big
name in many branches of industry. Today we present ourselves
as a medium-sized company
which offers a diversified product
range in the business sectors of
plastic engineering, suction dredgers and armoured pumps.
The developments in our special
field of polyurethane chemistry
originated from the material-specific experience gained in the former core business of pump manufacture for the transfer of abrasive
solids.
Since 1967 Habermann has manufactured mouldings and coatings with high demands of functionality, accuracy in fitting and

of experience
®
service life for application cases
in practically the entire industry.
We have used the experience formerly gained in implementing state-of-the-art wear-reducing polyurethane technologies for pump
manufacture and concentrated on
the development and production
of formulas and special formulations at our Witten location.
As in the past, the increasing requirements of our customers are
always the reason for permanently further developing our special
formulas, in order to meet the demands of prominent machine
parts made of polyurethane.
We attach particular importance
to target-oriented new developments. Dynamic synergies result
from tests in the contiguous business sectors of the Habermann
company. The possibility of carrying out a sufficient number of
test phases in our own installations and setting up regular test
monitoring arises here. Our objective is to test new products under conditions which are as close
to practice as possible, so that our
customers benefit from the highest level of product safety.
In our plastics processing department, the relevant advantages of
Hawiflex®, such as cut resistance,
wear resistance and oil resistance,
are optimally brought to the point
in our formulations.
Our polyurethane engineering division is a major division in the
company nowadays. The main investment areas lie in expanding
the technically possible manufacturing technologies.
Our long-standing loyal customers include well-known customers from a large number of branches
of
industry.
Special
formulations with the trade name
Hawiflex® have established themselves in the market and offer significant long-term advantages.

as a solution
in wear
protection
Increases in service life of 3-7 times in comparison with rubberlike materials are frequently obtained with mouldings and
coatings of Hawiflex®. This is
done by inserting special additives
to the formulation of the raw
materials. The Habermann-knowhow enables us to process highquality systems that are only
suitable for hot cast machinery.
Our plants and machines comply
to the formulations precisely by
computer-controlled processes.

Hawiflex® sheeting is extremely
versatile. Apart from further processing by punching it to produce
seals, spacers, slip rings or similar,
its use for wearing protection tasks
should be emphasized in particular.
Hawiflex® has a noise-absorbing
effect and protects bunkers, silos,
mixers, slides, chutes, loading
equipment, walls and bottom components. As a rule, the combination
of hardness and wear-resistance
cushions the bulk material.

Planning
First piece
As a specialist for the development and processing of high-tech
plastics, we have been working
successfully on the production of
the high performance elastomer
Hawiflex® since 1967.
After completion of the mould, we
make the first casting. Our customers can now satisfy themselves
that the planning discussions with
regard to the dimensional accuracy and functionality have been
correctly implemented.
Individually tailored solutions are
designed in close cooperation
with our customers.
We select the optimum solution
for you from our formula portfolio. The following are considered
when making the decision:
Service conditions, physical and
chemical demands and the possible process.
Production
Our modern machinery allows us
to provide our products with a
consistently high level of quality.
Our plants can be used to process
castings with piece weights from
a few grammes up to piece
weights of 450 kg. Production takes place precisely to our specifications and requirements.
Mould construction
Quality
The first step in the implementation of the planning discussions is
the preparation of the mould layout. Modern design and manufacturing processes enable low-cost
mould construction, especially for
small and medium-sized batches.
We use state-of-the-art products
and methods. Trained personnel
monitor, check and log our processes at the crucial points.
Our quality management system
complies with EN ISO 9001:

Hawiflex®
four decades
of experience
Hawiflex® our
materials
Hawiflex® is our name for materials belonging to the group of the
elastomers on the basis of various
polyurethane raw material systems. They are the result of 40
years of experience in the development of formulas and the requisite process engineering.
In order to be able to ensure that
our formulations are used at a
high level of quality in as many
customer sectors as possible, we
concentrate on the production and
processing of hot-moulded polyurethane systems. Significant service life advantages are obtained
through hot-moulded polyurethane materials.
Hawiflex®
four decades of
material development
For quality reasons, our raw materials are only processed by machine. We thereby guarantee a
constant property profile of our
products.
Physical characteristics
Hawiflex® material systems have
been created for use under the
roughest operating conditions.
High abrasion resistance with excellent tear and tear propagation
resistance are attributes of our series of materials. Materials with
exceptionally high demands of
dynamic loadability are available.
Hardness
35 Shore A – 95 Shore A
58 Shore D – 80 Shore D
Temperature characteristics
Chemical properties
As is the case with other plastics,
the characteristics of our Hawiflex® standard systems are not
constant but temperature-dependent. In the case of dynamic loading, the balanced temperature
must be a maximum of 80° C, in
order to prevent material fracture
and cracking. Short-term peak loads up to 120° C are permissible.
Special formulations for permanent loads above 80° C are available from our company.
We have materials with extremely good chemical resistance
against neutral oils and greases,
petrol and various solvents. General effects of the weather, such
as solar radiation, oxygen and
ozone, do not alter appropriately
selected systems. We even have
standard products available which
resist strong hydrolytic and microbial attacks.
Hawiflex® becomes less elastic as
the temperature decreases. Applications down to - 40° C without
the materials becoming brittle are
normally possible without any
problems.
Hawiflex®
Production
processes
Casting
The raw materials are prepared in
modern dosing installations and
made available for the casting process. The actual casting process
takes place in casting moulds in a
virtually unpressurized environment. Significantly cheaper tool
costs in comparison with the injection moulding thereby arise. A
pressure-resistant tool structure is
not required. Materials in the
hardness range of 35 Shore A to
80 Shore D are available for the
processing operation.
Hawiflex®
puts ideas into shape
All the important processes for the
manufacture of high-grade articles
are available in-house.
Rotational moulding
Spray application
Here the workpiece to be coated is
inserted in a suitable rotating mechanism.
Sprayed-on coatings provide an
alternative to rubberizing. The coating is applied in a spraying process similar to the airless process.
The coatings are seamless and do
not form any weak points for detachment. The material can be
applied more thickly in the wear
area. In comparison with lining
with sheets, significant service
life advantages with identical materials can be obtained through
material concentration in the active wear area.
The molten plastic is introduced
into the component under rotation. The material is distributed in
the workpiece through the effect
of centrifugal force. The advantage of this process is the significantly lower moulding costs.
Compared with the casting process, the inner core of the mould
is not required. Only considerably cheaper flange rings are normally required. Several installations are available for coating
rotationally symmetrical components.
