wire drawing machinery
Covering all the production steps
Wire drawing machines and lines
developed by Niehoff cover all
production steps from wire rod drawing
to fine and super fine wire drawing.
The machines and lines are being used
worldwide to produce wire made of
copper and copper alloys, aluminium and
aluminium alloys, plated copper wire, as
well as superconducting wire, bi-metals
wire eg copper clad aluminium and steel
wire and other kinds of composite wire
and wire made of special non-ferrous
materials.
The multi-draft rod breakdown machine
type M85 is by far the most popular
machine of its kind in the world.
The experiences gained with these
conventionally driven machines have
been the basis of the electronically
controlled rod breakdown machines type
MSM85 which are in industrial operation
since 1998.
As each capstan is individually driven, for
each draft different wire elongations can
be realised in a wide range. In the same
way slip on the drawing capstans can be
reduced to a minimum resulting in wires
with an especially high surface quality.
The MMH multi-wire drawing machine
with an integrated RM continuous
annealing system can simultaneously
manufacture up to 42 wires. All wires
have highly homogeneous characteristics
and a high surface quality and meet or
exceed the highest specifications and
processing requirements.
Niehoff has introduced the latest
electronic control and drive technology
from the MSM85 rod breakdown
machine into the MMH multi-wire
drawing machines for plated wires and
special applications. Besides the multi-
wire drawing machines for copper,
8-and 16-wire drawing machines for
aluminium and aluminium alloy wires
are also available.

Kieselstein’s multiple wire drawing machines
Kieselstein Group, Germany, consists of several wire related
companies, including Kieselstein GmbH which has the knowledge
and the sales rights for the former Herborn+Breitenbach and
SKET wire drawing products.
Kieselstein is internationally known as a partner in the development
and manufacturing of innovative wire drawing equipment,
and offers comprehensive service, spare parts and retrofitting of
second-hand drawing machines (Herborn+Breitenbach and SKET).
The company’s product range includes the Rubin multiple wire
drawing machine for the manufacturing of high-carbon steel wire,
stainless steel wire, low-carbon material and non-ferrous metals.
Using the company’s modular system it is possible to combine individual blocks, sections with different dimensions of the drawing
capstans, to machines suitable for any drawing task. The machine operates torsion-free and features an intensive water-cooling
system. Kieselstein also specialises in bull blocks for applications including spring wire and cold-heading wires.
Kieselstein International GmbH is another main company of the group, and produces draw-peeling machines focussed on superior
wire surface quality. The draw-peeling process enables the removal of marginally decarburised layers, rolling cracks, score marks and
pores. The result is a faultless, very smooth surface and a nearly homogenous structure.
