The PWC-S system performs drawn wire cleaning and polishing, in-line with wire drawing machine at 6 to 12m/s (1,200 to 2,400ft/min).

Exceptional cleanliness is obtained in a glossy finish in plating quality permits wire direct brass coating, copper coating, and wire cleaning prior to heat treatment including patenting, annealing, painting, plastic coating, etc.

In demanding applications, including production of highly reflective wire, the system revolutionises the wire cleaning, enabling considerably higher surface quality of the end product.

The PWC-S cleaning system incorporates new technology which enables plant cold water to be converted into a unique multi-action high pressure wetting/displace/flush cleaning liquid used to clean drawn wire at high-speed, providing the wire with a smooth glossy finish in plating quality.

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 burned lubricant tightly bound to the wire surface and embedded in micro-cavities.

These cavities are further smoothly polished under extreme pressure generated by the unit all around the wire circumference, separating lubricant residue from base material, washing away dispersed contaminants, enabling wire exiting the unit very clean of white-metal appearance with bright finish and completely dry.

For wire decorative applications, the system can be used with emulsion including a new rust preventive additive diluted at 5 per cent concentration.

The PWC-S system provides the ultimate combination of simplicity and effectiveness in a completely green process: acid-free, caustic-free, without ultrasonic, without chemicals, hermetically sealed zero-emission system, no fumes, no foam.

Economical and environmentally friendly, the system provides significant process savings in 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.
