Feature Wire cleaning, treatments & finishes

A unique partner for wire cleaning Candor Sweden AB, founded in 1946, specialises in advanced wire cleaning and plating plants for various applications. The company was founded as a chemical supplier and it uses this know-how and experience in chemical processes with the advanced equipment for cleaning and plating of wire. Candor has a wide selection of wire cleaning plants to offer, such as hot water spray cleaning, ultrasonic cleaning and electrolytic cleaning. Which technology to use is a balance between wire speed, cleaning requirements, type of lubricant used and environmental aspects. In many cases, especially for high speed applications, the processes can be combined as separate steps after each other in a plant. This way a hot water cleaning unit can be dedicated to remove sodium-based lubricants and an acid ultrasonic or electrolytic process can make the fine tuning of the already pre-cleaned wire if required.

Candor also offers single- and multi-wire plating lines for ferrous and non-ferrous materials, and all plants are tailor made to the customer’s specification.

Wire green cleaning for plating and decorative bright finish

The simultaneously performs drawn wire cleaning and polishing, in-line with the wire drawing machine in a totally green application. Exceptional cleanliness obtained in a glossy finish and the plating quality permits wire direct brass coating, copper coating, galvanising, plating, Al and Cu cladding and wire cleaning prior to heat treatment. For a clean mirror reflective wire finish, for decorative applications, the system can be used with a conventional emulsion diluted with water at 3-5 per cent concentration. The PWC incorporates new technology that enables normal plant cold water to be converted into a unique cleaning medium generating pressure wetting/ contaminants extreme pressure extrusion/ PWC system

polished under high pressure generated by the unit, enabling wire exiting the unit to be very clean, of white-metal appearance with reflective finish and totally dry. the ultimate combination of simplicity and effectiveness: acid-free, caustic-free, without ultrasonic, without chemicals, hermetically sealed zero-emission system, no fumes and no foam. Economical and environmentally friendly, the system provides significant process savings in the 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. Decalub – France Website : www.decalub.com The PWC-S system provides

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 burnt lubricant tightly bound to the wire surface and embedded in micro-cavities which are further smoothly
