Production of
dip forming wire
Dip-forming process is the type of continual
casting process based on passing of the core
wire through the melted copper in the casting crucible. Cold core wire absorbs the
heat from the melted copper and cools the
copper around the wire surface which crystallizes and sticks on the core wire surface.
After casting in the casting crucible wire
is hot rolled. By hot rolling process is produced round copper rod, dimension of 8,12,
14,16,17.5mm in diameter. All dimensions
obtained by hot rolling process is also produced with the silver content of 0.03 to 0.1 %.
Advantageof dip-forming process compared
with other processes are:
-Superior quality and possibility of further processing;
-Less breaks in the drawing process which
leads to the decreasing of the waste in
the cable and enameled wire production;
-Working conditions in dip forming plants are
much better than for other production procedures;
-Electrical energy used for melting makes this
process friendly to the environment protection.

Production of profiled
copper wire & trolley wire
Copper wire factory production program includes production of
round and profiled copper wire.These types of wire are produced
by cold rolling and drawing process. Round and profiled wire is
produced in quality types F20;F25 and F30 , depending of tension
strenght value.Trolley wire is according EN50149 standard.
Production according to the customer demands is also possible
as well as according to the standards.
Wire is packed on the coils with inner diameter of 350mm and
outer diameter of 620 to 650mm.Coils are wrapped by plastic foil
and packed on wooden pallet dimensions of 620x620mm or
900 x 900mm.
Each shippment is accompanied by Quality Certificate as guarantee of quality demands fulfillment.
Mechanical equipment of plant, together with clasical tool machi
nery ( lathes; grinding machines for flat grinding to the diameter
of 600mm and height up to 450mm) consist of PeTeWe grinding
machine for profiled grinding and EDM machines based on principles of electric erosion in metal processing used mostly for
production of tools and rolls for production of round and profiled wire.
Profiled copper wire and
trolley wire is used for :
• Production of transformers
• Production of electric motors
• In automobile industry
• For further isolation by:
-paper
-silk
-enamel
• As trolley wire

Powder metalurgy products
Technology for production of powder metallurgy
semi products or final products includes pressing of
different powder mixtures (mostly by mechanical
pressing) , than heating – sintering on temperature
which is slightly below the melting temperature of
powder or powder mixture.
Advantages of powder metallurgy products are:
-Possibility or production of extremely complicated
parts precise in dimensions
-Possibility of obtaining alloys with high and different melting temperatures which can not be obtained
by traditional casting methods
-Low production costs
-Quality of alloys obtained by powder metallurgy
technology is superior in comparison with casted
alloys with the same content
Assortment of the powder metallurgy products produced in Copper wire factory includes:
- Sintered friction dry and oil plates used in power
transmission gears (oil) and for breaking elements
(dry)
- Bi-metal elements based on sintered brass used
in oil systems of axial-piston pumps of high pres
sure
- Sintered electric contact elements, i.e. coppergraphite blocks used for making electric motor’s
brushes .
Powder metallurgy
products are used for :
- Civil engineering
machines
- Agriculture machines
- Mining machines
- Heavy vehicles
