How Does It work Murua electro-finisher delivers an easier, faster and more effective finishing result for Gold, Silver and Brass. Inside the finisher, workpieces are immersed in a special solution that coats the metal surfaces. The finisher, based on mechanicalgalvanic principles, uses mechanical agitation to bombard the piece with tiny particles of plastic media. As they bump against the workpiece, the particles temporarily disturb the coating, allowing the charged bath to cause electrolytic depletion to smooth and polish the metal surface - even the finest details and crevices of the design in the fraction of a second before the coating is restored.
