On-line range for accuracy and control

measurement and control on high-speed extrusion lines with one gauge (ODEX®) X-ray measuring systems for

Zumbach's range of non-contact on-line measuring and control instruments is in use worldwide for dimensional parameters including diameter, thickness and eccentricity, out-of-round and for physical or electrical parameters including expansion, capacitance and dielectric strength. Zumbach technology, such as lasers/ optics, ultrasonics, x-ray, high-voltage technology, computer hardware and software, is used in the cable and wire industry for telecommunication wire, data wire, power cable, electronic and control cable, fibre optic cable, on extrusion lines of singles and jackets, CV-lines and rewinding stations. Zumbach’s patents for measuring and control instruments include: Highly accurate diameter and ovality measurement with 1-axis, 2-axis and 3-axis laser scanners (ODAC®) Non-contact measurement of coating thickness with ultrasonic wall thickness scanners (UMAC®) Eccentricity/concentricity and diameter and true minimum wall • • • In-line Pressure Wet Cleaning (PWC) system cleans drawn wire of residual lubricant to obtain a smooth and glossy finish of ‘ plating ’ quality, at up to 14m/sec (2,800 ft/min) depending on wire size. The system simultaneously performs in-line surface cleaning and polishing with drawing, and uses standard cleaning media including cold water or oil for the most demanding wire cleaning and polishing applications. The wire leaves the cleaning unit completely dry, ultra-clean, with a highly reflective appearance. particularly recommended for cleaning applications in which a traditional process is inappropriate, especially with wire drawn in severe conditions resulting in increased heat and burnt lubricant tightly bound to the wire surface and embedded in micro-cracks and longitudinal scratches. The exceptional cleanliness of the glossy finish permits direct coating, in brass or copper for example. Wire cleaning prior to heat treatment applications include patenting and annealing.

Wire with ‘ new-coat ’ in bright finish for plating quality Advertorial on behalf of Decalub

In demanding applications, such as pro- duction of highly reflective wire, the PWC system enables considerably higher surface quality of the end product, benefiting from the Decalub ‘ new-coat ’ process with controlled nano-film lubrication. This permits wire polishing and smooth and frictionless drawing with water soluble sodium lubricants in all drafts, easy to clean in-line at high speed with ‘ rust preventive ’ additives.
