New scanners for wall thickness measurement Zumbach Electronic has introduced two new ultrasonic wall thickness scanners. With a completely new design – patents pending – the transducers can be synchronously adjusted to the best possible measuring position within seconds. This process can even be motorised. The scanners cover an outside diameter range from 5-100mm (0.2-4"), depending on the model. They represent a smart and simple solution for fully non-contact, in-line wall thickness measurement of cable jackets, tube and hose. In combination with the proven Wallmaster data acquisition, processing and display system from Zumbach, a full process control can additionally be accomplished.

UMAC Z50 Scanner with 6 measuring points. The same model is also available for 4 point measurement

Tungsten carbide products from India Kay Pee Dies & Tools, India, manufactures tungsten carbide products for applications including drawing, heading, extrusion, forming and wear resistance, for use in wire drawing, profile extrusion, and the production of bright bar, fasteners, and conductors. Rough cored dies in a variety of pellet sizes, carbide grades, hole sizes, approach angles and cases are available from stock, or custom design dies with special angles, bearings and grades can be made. They also offer advice on all aspects of die management, including selection of proper pellet sizes, repair and re-cutting of dies, and inventory management/die history record.

They are all manufactured according to DIN specification – as well as to customers’ specifications. For almost a year OML has produced reels on cardboard and packings of all kinds in both cardboard and wood. Production, regulated by CAD-CAM proceedings, allows the control of all machines and guarantees the parameters of the process and quality.

Frictionless drawing of High-Carbon wire

The new PDH lubrication system is used in the most demanding drawing applications, allowing the highest drawing speeds, with all carbon steel rods/wires, mechanically descaled or acid cleaned, bare or pre-coated, bright or galvanised, and in production of high quality wires, including spring, rope, bead, PC strand, stainless steel spring and alloys, galvanised H/C wire, AL-clad wire, plating wire, reflective bright wire, CO 2 welding wire and colleted nail wire. The PDH lubrication system benefits from the unique fully controlled 3-way interaction between the pressure, temperature and lubricant viscosity, completely eliminating traditional wet pre-coatings for all drawing applications form rod to wire, including mechanically descaled 0.90 per cent C rod drawn without pre-coating chemicals. The system permits ‘frictionless’ drawing with the full lubricant film at wire-die interface (physical separation of metal-to- metal contact), automatically controlled, thanks to the innovative PDH rod/wire dry coating/lubrication technology enabling automatically controlled fusion of the lubrication compound. Such a liquefied substance, with controlled viscosity, performs an exceptionally consistent and hard residual coat, adjustable in weight at all speeds, eliminating the need for phosphate and borax pre-coating chemicals and their substitutes. This new wire coating/lubrication system allows a wide range of residual coats, strongly adherent for high-tensile wire, and light water soluble coat for plating wire. One of the typical applications of the PDH system includes drawing from

5.5mm (0.218") diameter, 0.83/0.88 per cent, mechanically descaled rod, directly, without pre-coating, with an output of 2.2 tonne/hour, and with a die life of 200 tonnes/die in the first draft and a die wear of 0.30 micron/tonne of wire drawn in the last draft.

In other multi-draft H/C applications, the finishing die produces 40 to 60 tonnes of wire drawn without pre-coating chemicals, with wire properties (ductility, cast and torsion test) improved and exceptionally consistent. The PDH lubrication system features ‘zero’ energy consumption, self generating processing heat and pressure. It is easy to install on any wire drawing machine and it can be operational within 2-3 hours. Decalub – France Fax : +33 1 60 20 20 21 Email : info@decalub.com Website : www.decalub.com
