When you are looking for a robust and
powerful timing belt drive that also is a
paradigm for successful industrial design,
you cannot help checking out the Joachim
Uhing KG portfolio.
The motorised AZ 1040 succeeds the tried
and tested AZ 2004 the company, based at
Mielkendorf, has been selling since 1991.
The AZ 1040 has the potential to quickly
take the place of its predecessor in the
Uhing product range and to become the
bestseller.
Even at first glance, it convinces by its
design, giving you an idea of optimal
applicability: the one-piece profile with
integrated carriage guide allows for greater
free stroke lengths than were possible with
AZ 2004.
Compared to the previous model, several
installation and attachment options were
added to the AZ 1040. For this purpose,
head pieces made of the same profile as
the drive itself were integrated.
The T-slots are an integral part of the
profile and facilitate mounting of
additional attachments. Slide blocks can be
inserted laterally.
Like all Uhing timing belt drives, the
AZ 1040 is made of a bend-proof and
torsion-proof aluminium profile. A belt
lock fastened to the roller-mounted load
carriage transmits the power from the
timing belt to the load carriage running
on round, corrosion-proof and hardened
guide bars mounted on the aluminium
profile.
Uhing offers the new timing belt drive
as a complete pre-assembled unit with
motor, making assembly and installation
fast and smooth. The AZ1040 proves to be
particularly practical because its motor can
be mounted in several positions.
This feature more or less excludes space
issues design engineers have often to deal
with when integrating such units.
During operation, the AZ 1040 proves to
be particularly robust and powerful. The
carriage covers a distance of 200mm per
shaft rotation.
The motorised drive features a maximum
traversing speed of 5/s and an idling
torque of 0.7Nm. The dead weight of the
drive for a stroke of 0mm is 9.1kg, the
weight per 100mm stroke is 0.9kg. The
carriage weighs 2.3kg.

Colorant Chromatics produces a
full range of high quality colour
concentrates, speciality compounds,
pigment dispersions and inks for
processors of fluoropolymers and high
performance plastics.
The company is promoting a new range
of reinforced fluoropolymer compounds,
in particular its compounds for foaming
of PVdF; carbon fibre compounds
in PVdF, ETFE, ECTFE and PFA; glass
fibre compounds in ETFE and PFA;
cross-linkable ETFE (X-ETFE) and PVdF
(X-PVdF), and PEEK compounds.
Colorant Chromatics’ extensive
melt-processable product line includes
colour concentrates and compounds for
polymers including FEP, ETFE, PFA, PVdF,
ECTFE, MFA, THV, PEEK, and polysulfone
(PES, PSU and PPSU). The colour
concentrates are offered in various
pigment strengths and resin viscosities.
In addition to its standard line of
colours and compounds, the company
offers special services such as colour
matching, pre-colouring and custom
compounding, and supplies a full
range of pigment dispersions for PTFE
extrusion, as well as printing and
striping inks for FEP, ETFE, PFA, PVdF
and PTFE.

The PWC-S cleaning system incorporates
new technology which enables normal
plant water to be converted into a unique
multi-action high pressure wetting/
displace/flush cleaning liquid used to
clean drawn wire at high-speed, providing
a smooth and glossy wire finish in plating
quality.
The system simultaneously performs
surface cleaning and polishing, in-line
with wire drawing machines at 6 to 12
m/s (1,200 to 2,400ft/min).
Exceptional cleanliness obtained permits
wire direct brass coating, copper coating,
and wire cleaning prior to heat treatment
and coating applications including
patenting, annealing, painting, plastic
coating, etc.
The PWC-S system effectively loosens and
removes lubricant residue from the base
material and is particularly recommended
for cleaning applications with wires
drawn upon severe conditions resulting
in increased heat and burned lubricant
tightly bound to the wire surface and
embedded in microscopic cracks.
The system can be used with an emulsion
including a new rust preventive additive
diluted at 5% concentration.
The system provides the ultimate
combination of simplicity and
effectiveness: acid-free, caustic-free,
without ultrasonic, without chemicals,
hermetically sealed zero-emission system,
no fume, no foam.
Economical and environmentally friendly,
the system provides significant process
savings in production of clean wires.
The PWC-S unit is compact and can be
easily installed on the finishing/last block
of a wire dry drawing machine.
