wire cleaning
Candor Sweden AB, founded in 1946, specialises in advanced
wire cleaning and plating plants for various applications.
The company was founded as a chemical supplier and it uses
this know-how and experience in chemical processes with the
advanced equipment for cleaning and plating of wire.
Candor has a wide selection of wire cleaning plants to offer, such
as hot water spray cleaning, ultrasonic cleaning and electrolytic
cleaning. Which technology to use is a balance between wire
speed, cleaning requirements, type of lubricant used and
environmental aspects.
In many cases, especially for high speed applications, the
processes can be combined as separate steps after each other in
a plant.
This way a hot water cleaning unit can be dedicated to remove
sodium-based lubricants and an acid ultrasonic or electrolytic
process can make the fine tuning of the already pre-cleaned wire
if required.
Candor also offers single- and multi-wire plating lines for ferrous
and non-ferrous materials, and all plants are tailor made to the
customer’s specification.

PWC
system
simultaneously
performs drawn wire cleaning and
polishing, in-line with the wire drawing
machine in a totally green application.
Exceptional cleanliness obtained in a
glossy finish and the plating quality
permits wire direct brass coating, copper
coating, galvanising, plating, Al and Cu
cladding and wire cleaning prior to heat
treatment.
For a clean mirror reflective wire finish, for
decorative applications, the system can be
used with a conventional emulsion diluted
with water at 3-5 per cent concentration.
The PWC incorporates new technology
that enables normal plant cold water
to be converted into a unique cleaning
medium generating pressure wetting/

Wire cleaned for decorative finish by the PWC
system
Wire green cleaning for plating and decorative bright finish
hydrodynamic cavitations displacement
and contaminants flush out. The PWC-S
system effectively loosens and removes
lubricant residue from base material and
is particularly recommended for cleaning
applications with wires drawn upon
severe conditions resulting in increased
heat and burnt lubricant tightly bound
to the wire surface and embedded in
micro-cavities which are further smoothly
polished under high pressure generated
by the unit, enabling wire exiting the
unit to be very clean, of white-metal
appearance with reflective finish and
totally dry.
The
PWC-S
system
provides
the
ultimate combination of simplicity and
effectiveness:
acid-free,
caustic-free,
without ultrasonic, without chemicals,
hermetically
sealed
zero-emission
system, no fumes and no foam.
Economical and environmentally friendly,
the system provides significant process
savings in the production of clean wire.
The PWC-S unit is compact and can be
easily installed on the finishing (last
block) of a wire dry drawing machine.
