Wire cleaning for plating quality

Decalub’s new in-line Pressure Wet Cleaning (PWC) system is used to clean drawn wire of lubricant residue to obtain a smooth and glossy finish to ‘plating’ quality, at a rate of 6 to 14 m/s (1,200 to 2,800 ft/min) dependent on the wire size. The system simultaneously performs surface cleaning and polishing, in-line with the wire drawing machine and is used for the most demanding wire cleaning and polishing applications using standard cleaning medium including cold water, water emulsions and oil. 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. Exceptional cleanliness obtained in smooth and glossy finish in ‘plating’ quality permits wire direct brass coating, zinc coating, copper coating or painting, and wire cleaning prior to heat treat- ment applications including patenting, annealing, welding and cladding. The PWC system is

In demanding applications, including production of highly ‘reflective’ wire, the PWC system revolutionises the wire cleaning, enabling considerably higher surface quality of the end product. The new Decalub wire intermediate dry re-coating process, permits a smooth and ‘frictionless’ drawing with completely water soluble sodium lubricants in all drafts, easy to clean in-line at high speed with ‘rust preventive’ additives. As a consequence, the PWC offers significant downstream benefits and process savings with the potential to replace acid and ultrasonic methods.

Programming made easy ... Simply programmed via touch-screen with animated icons and using CAD coordinate input, Pave Automation believes Panther X3 to be the easiest to programme machine the company has produced.

Simple, but not basic – this latest 13-axis wire bending machine is designed for sequential forming of three-dimensional components of 1.5mm to 6.35mm in diameter and up to 3m long. Six bending shafts offer the forming of multi radii – up to 12 differing selections can be programmed – and 13 programmable axes allow sequenced operations to be performed that were never previously possible. These include the use of a single forming mandrel to produce up to three different radii. Panther X3 offers carriage speeds up to 80m per minute, and ten bending speeds up to 0.05 seconds for 180º.

Three bending shafts per bending head ensure repeatability on angles of ±0.05º. For ease and reliability, Panther X3 is coil fed with a twist-free wire straightening system to maintain efficient throughput. X3’s clamp unit allows 360º rotation with ten programmable speeds up to 0.02 seconds for 90º.
