Taking care of
small diameters
Increasing manufacturing efficiency
and product quality is ever-important in
these competitive times.
The cost and the quality of products
are essentially determined by the dies
used and demand resulting from this,
with regard to improved geometric
drawing parameters, presupposed
a sustained further development of
the drawing die processing machines
currently in use.
There are two new developments in
the wide range of tungsten carbide die
working machines from Bremer GmbH
in Germany.
The company has developed the
new KSP1 and EK2000F machines,
especially for small diameters in the
range of 0.12-1mm.
In the range of 0.40-6mm Bremer has
developed a fully automatic machine,
the KPM4AC.
Both types of machines are using
modern computerised technologies
and built-in electronic systems.
At first the dies are automatically
processed to the meeting point. After
the conical section is worked, the dies
are automatically transferred to the
calibration station, which calibrates
the bearing section of the die with an
accurate tolerance of 0.001mm.
The system continuously checks the
bore diameter and the whole cycle
which ensures very close tolerances for
radii angle and bore diameter.
These latest developments can elimi-
nate the human factor and produce
a perfectly controlled die quality.
To increase customer service, and to
provide optimum technical support to
all Asian customers, Bremer also has
two agent offices in Asia, in Osaka,
Japan, and Shanghai, China.

Handling fine wire applications
Huestis has introduced a compact fine wire pay-off for
strand annealing furnaces.
The FWP1000 is designed
to handle fine wire appli-
cations with very low
process tension.
The stand incor-
porates an AC
variable speed drive
and an integral dancer
utilising a dancer duty
potentiometer.
Combined with
an adjustable
counterweight,
the unit is
capable of
handling fine wire
as small as 0.005"
diameter.
Built for maintenance free
operation, the stand uses
lightweight aluminum sheaves with ball bearing and hard
coated v-grooves.
Quick lock arbor collars allow for spool changes without
tooling. The dog pin plate includes an adjustable dog pin.
Extremely compact, much less than two square feet, the
design allows for single or multiple station installation.

Experience is golden!
With more than 25 years’ experience, Pleuger is one of
the leaders for hot-drawing machines for noble materials
like gold, silver, platinum and compositions.
The drawing
process usually
starts with Ø
0.6mm – outlet
of the extrusion
line – and ends
at about 2mm
or below 1mm,
d e p e n d i n g
on customer
requirements.
The time-saving
drawing process
is very gentle
to the surface
of the material
and there are
a number of
advantages in comparison to the standard cold-drawing
machines.
Both the drawing temperature and speed are adjustable.
In addition to those drawing machines Pleuger, based
in Altena, Germany, also produces pay-offs, take-ups,
wet and dry-drawing machines, spooling machines and
hot-straightening machines for special materials.
