OVERVIEW

What is Murua?


- Grinding + Polishing in one short step.
- Fully automated, high performance.
- Perfect finishing for gold, silver & brass alloys

Murua is a grinding and polishing systems for gold, silver and brass alloys. It can process various pieces at same time in one only fully automated step. It is specially designed for goldsmiths, as it allows more time to design, by reducing the time spent on surface finishing work.

How does it work?

The Murua Gold electro-finisher delivers an easier, faster and more effective finishing option.

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.

Why choose Murua?

1. GRINDING AND POLISHING IN ONE STEP?

From cast to mirror-finishing polishing in just one step. Completely automated process.

2. BIG TIME SAVINGS

An optimal performance is achieved, due to a high energy extraction process. At same time, the whole process is carried out using the same machine, reducing the waiting and preparation time. It is even possible to process 3 pieces simultaneously.

3. POLISH COMPLEX PARTS WITHOUT DISASSEMBLING THEM

The polishing action reaches every corner of the piece, so it can process articulated pieces, such as necklaces, or interior walls which can not be accessed mechanically.

4. GEMSTONES AND NON CONDUCTIVE MATERIALS WILL NOT BE AFFECTED

Pieces can be processed without removing embedded gems, which will not be affected and will maintain their original properties. The dielectric parts are also unaffected by the process.

5. MAINTAINS THE GEOMETRY OF THE PIECE

The process, unlike mechanical ones, does not rounds edges, and can penetrate in all dead zones. These attributes, along with the extraction performance, allows for the creation of new designs, which would not have been feasible until now.

6. LOW LOSS RATE FULLY RECOVERABLE

The process achieves the highest polishing quality with minimal removal of material. All the extracted material is deposited on the cathode, from where it can be completely recovered.

7. EXPERTISE IS NOT REQUIRED

The process, being fully automated, does not require any specialized labor. It also enables the industrialization of pieces by removing the differences between them.

8. LOW MAINTENANCE AND CONSUMABLES COST


The treatment process does not require any abrasive items, which prevents a constant expenditure on consumables.

9. ENVIRONMENTALLY FRIENDLY

No environmentally harmful materials are used during the polishing process or on recovery of the extracted material.
