Cast-rolled wire, single and

OUR ASPIRATION
One for all.
Our cast-rolled wire.
M
KM wire rod is an essential primary material in
many sectors of industry. Solar engineering, wind
power, power engineering, heavy current engineering,
automotives – to name but a few – all require copper
wires, multiple wires, stranded wire and wire rope.
There are a large variety of manufacturers of copper
wire. The market requires so many different applications that demand for wire rod – and all of its finished
derivatives – is rising rapidly.
Not all copper processers have their own foundries.
Depending on demand, some specialise in processing single wires, some multiple wires. Others work
only with finished stranded wire by extruding it to
produce cables. MKM’s self-cast, wire rod is used as a
primary product for all of our drawn wire sizes. MKM
supplies standard wires as well as custom-made wires
such as special wires for very small industry niches.
But at the front end is our most important product:
cast-rolled wire.

Drawing on experience.
E
ver since it was founded in 1909, MKM has had a completely integrated and closed production cycle. That
way we keep our production cycle closed and in our hands.
After all, only with good quality wire rod can you make
something even better.
Our expertise – your gain
The Contirod® technology upstream of our wire production ensures that founding, casting, de-burring, pre-rolling,
finished rolling, cleaning and winding all take place in one
continuous process without interruption. It’s set standards
in the market and we pass the benefits on to our customers
directly. Years of experience allow us to keep full control
over the quality of our material. That means MKM always
achieves the appropriate quality for the application in
hand, at every stage and for every product.
Another advantage for our customers is that because every
coil is examined directly, inclusions such as tiny iron particles or rough surfaces can be detected and screened out
immediately. For customers this means no more time-consuming coordination with separate foundries; to us it
means direct everyday contact between colleagues.

■■ product- and order-specific packaging
Setting up a redrawing machine. Copper wire drawn to the required
thickness changes its mechanical properties – it becomes harder.
Heating it up again in a continuous annealing furnace re-establishes
its metallurgic structure.

This is where
we’re in our element.
B
y element we don’t mean water, we mean copper.
MKM can now draw up to 24 wires simultaneously –
from 0.50 mm to 0.05 mm.
We manufacture bare and tinned wires on over 100 machines. Tin protects copper against oxidation and against
chemical reactions during extrusion. It also facilitates improved soldering for certain applications. The maximum
tin coating thickness on pre-drawn wire is around 20 μm.
This allows tinned wires to be drawn down again to 0.05
mm, guaranteeing a final, fully covered tin coating of at
least 0.4 μm.

Tin coating
Tin coating as a total tin coating on pre-drawn wires to
customer specifications
Total tin coating on finished wires:
0.05 mm to 0.14 mm min. 0.4 μm
■■ Above 0.14 mm to 0.29 mm min. 0.6 μm
■■ Above 0.29 mm min. 0.8 μm

Wires as fine as hairs run almost invisibly around 16 parallel capstans and
drawing dies on a multiple wire drawing machine. The emulsion lubricates
and cools so that the wires do not break or overheat.

We always deliver.
Delivery
All of our products come in specially made, standard-compliant, secure packaging. Our packaging guarantees retention of shape, ensuring that a product’s
properties are preserved to the utmost after leaving the
factory. Sea-worthy packaging is also standard for our
overseas clients. We can also assess individual requirements provided they can be presented as a drawing.
