Unavoidable fines (abrasive particles)
generate the most destructive lubricant
contaminants in wire drawing. This is
no longer an alarming phenomenon
since the introduction of the Decalub
green and dry rod preparation and wire
lubrication including PDH coating system.
In the most demanding wire drawing
applications, the PDH die’s wear is
reduced to a unmeasurable level (about
0.2 micron per tonne), meaning that
three-body abrasive wear is virtually
eliminated. Generation of abrasive
particles (fines), the most destructive
lubricant contaminant, is continuously
liberated from the wire surface during
drawing and PDH captured, encapsulated
and transported with drawn wire from
block to block out of the machine.
The lubricant film created is of
such a configuration as to induce a
hydrodynamic lubricant activity causing
migration of all lubricant contaminants
without interference with the die,
meaning the removal of encapsulated
abrasive particles prevents die wear,
enabling wire frictionless drawing
at much higher speeds and lower
temperatures.
Applications include all plain carbon
wires up to one per cent carbon and
stainless steel alloy wires up to 26 per
cent chromium, coated or uncoated,
where the PDH high-performance specific
anti-friction coat is about 8 to 15 microns
thick, adjustable, largely sufficient to
retain liberated abrasive particles from
the wire surface.

HANNAY Reels recently introduced a new package of specialised fibre optic
reels to address the unique needs of the communications industry.
The reel packages are designed specifically for use with tactical and hybrid
fibre optic cable types, including Broadcast SMPTE, TAC and/or opticalCON.
A lightweight metal construction includes external and/or internal drum
storage with a protective grommet for easy access to cable, while also
providing protection from dirt and debris.
Featuring a non-reflective black matte finish to resist harsh outdoor
elements, the new Series AVF-14 and AVF-18 are well-suited for live events,
mobile broadcast units, mining operations, and military communication.
The new package includes:
Series AVF-14: A lightweight aluminium reel under 10lb designed for easy
transport and handling. Featuring a modular frame style, the handle and
leg can be easily replaced in the event of damage. Reel capacity ranges
from 350 feet of SMPTE cable and up to 3,500 feet of fibre optic cable.
Series AVF-18: A durable aluminium/steel reel weighing less than 25lb.
Featuring a unique frame style, the reel allows multiple reels to be stacked
on top of it for space saving. A strong 4" optional caster enables easy
transport with large capacities of camera cable. Reel capacity ranges from
1,000 feet of SMPTE cable and up to 9,250 feet of fibre optic cable.

There is direct/indirect impact on product
quality with tension variation beyond
certain limits in processes like extrusion,
stranding, bunching, twisting, rewinding,
coiling, weaving, coating, inspection,
drawing, enamelling or similar.
These processes have a direct impact
on the quality of the product, as well as
machine performance.
This results in the end product quality
being compromised in spite of the
willingness to give the best quality
product by the industry.
With the help of 25 years’ experience,
Puretronics is able to introduce a tension
measurement system, which is useful in
various applications.
In continuous production processes, the
quality of the finished products is directly
dependent on the accurate measurement
and control of the material tension, thus
improving finished product quality,
reducing waste, increasing processing
speeds and maximising efficiency and
low downtime.
