The Murua Gold electro-finisher delivers an easier, faster and more effective finishing option for gold jewelry pieces. Inside the finisher, workpieces are immersed in a special solution that coats the metal surfaces. The finisher, based on mechanical-galvanic 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.
This compact, innovative machine is specifically designed for gold workpieces and produces higher-quality results faster and more easily than traditional pre-finishing methods. It can accomplish the equivalent of six hours of cut-down tumbling or a complete finishing process in just minutes.
• Replace most pre-polish applications, both by hand and by machine; you can produce more quality work in less time and with fewer people.
• Load jewelry pieces onto the accessory hooks on the part holder (fixturing unit) that fits into the power head; choose from a variety of hook designs to best accommodate the size and shape of the pieces you want to finish.
• Gemstones and non-metal components need not be removed; they are left untouched and unchanged by this process.
• Protect the geometry of your workpiece--traditional mass-finishing methods don’t polish at an even rate, resulting in rounded edges and muted details. This revolutionary system polishes at an even rate, protecting your design.
• Easily recover the precious metal that is removed in this process. There are no abrasives mixed with the metal--just remove the cathode and send it to the refinery for metal recovery. No more trying to sweep up and collect dust filings--it’s all collected in the machine.
