The PWC-S system simultaneously
performs drawn wire cleaning and
polishing, in-line with wire drawing
machines at up to 12m/s (2,400ft/min), in
a totally green application.
Exceptional cleanliness obtained permits
wire direct brass coating, copper coating,
galvanising and wire cleaning prior to
heat treatment and coating applications
including patenting, annealing, painting,
plastic coating, etc.
The PWC-S cleaning system incorporates
new technology which enables normal
plant cold water to be converted into a
unique multi-action cleaner including
wetting/extreme pressure extrusion/
contaminants displace and flushing out
used to clean drawn wire at high-speed,
providing wire glossy finish in plating
quality.
For a clean mirror reflective wire finish, for
decorative applications, the system can
be used with emulsion including a new
rust preventive additive diluted at 3-5%
concentration.
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 burned lubricant tightly
bound to the wire surface and
embedded in micro-cavities.
These are further smoothly polished
under high pressure separating
lubricant residue from base
material, washing away dispersed
contaminants, enabling wire
exiting the unit to be very clean
of white-metal appearance with a
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, no foam.
Economical and environmentally
friendly, the system provides significant
process savings in 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.

Advantages of the new Inotec™ generation
Ask Chemicals has succeeded in further enhancing its inorganic Inotec™ technology
through its new TC 5000 and HS 3000 products. The new developments lead, in
particular, to improved shakeout and higher moisture stability of the cores.
The newly developed promoter TC 5000 complements the positive qualities of the
previous generation in regard to penetration-free and sand-adhesion-free casting
surfaces, and in terms of improved collapsibility properties in light metal casting,
improved immediate strength levels, as well as increased storage life of the cores.
Likewise, the storage life of cores manufactured using inorganic binders previously
posed a challenge, especially on hot summer days with high humidity and a high
ambient temperature. The new binder HS 3000 significantly improves the moisture
stability of the inorganically bound cores. This, in turn, makes it possible to manufacture
stable cores coated with a water-based coating, which also makes the binder system
interesting for iron casting.
