Electroforming

The production experience, acquired through the cooperation with our customers, has enabled us to create the new, unparalleled automatic machine AUROFORM MONOLITH which represents the most advanced, automatic gold alloy electroforming system for jewellery and watch industry worldwide.

AUROFORM MONOLITH is the NEW automatic machine, with one sole working module for deposition and weighing, covered by an international industrial invention patent, developed and manufactured by LTC-Caoduro and distributed by NUTEC International.

To reach AUROFORM MONOLITH technological level, LTC-Caoduro and NUTEC technicians have been working, for a couple of years, in cooperation with the major worldwide expert in the production of electroformed semi-finished jewellery components.

The aim was further improving the exceptional results already achieved with the automatic machine AUROFORM PLUS, and the outcomes are:

  • outstanding weighing accuracy, by automatically measuring and introducing the electrolyte density value during the weighing step;
  • consistent reduction of the process time, by directly weighing in the electrolyte;
  • maximum protection of the electronic balance from the very aggressive vapours developed during working.

AUROFORM MONOLITH: a new milestone in gold alloy electroforming.

ABOUT AUROFORM MONOLITH

monolith_rear

Meanwhine keeping the advantages of the former one, AUROFORM MONOLITH is not only a high performance, fully automatic electroforming machine, but it has been conceived to further improve productivity, flexibility, compactness and maximum precision at all parameters control level.

AUROFORM MONOLITH enables:

  • to deposit from 250 up to 1500 grams of alloy in one process;
  • an unparalleled carat distribution through the pieces on the rack;
  • a weighing accuracy never achieved before in a automatic system;

AUROFORM MONOLITH ensures, with the highest production flexibility, that:

  • THE WEIGHT DEPOSITED IS EXACTLY THE REQUIRED ONE
  • THE DESIRED CARAT IS OBTAINED WITH THE MAXIMUM GOLD SAVING!

FOR THE SAKE OF THE OPERATOR

Once the rack with the mandrels is introduced into the machine drawer, the few process identifying data (carat, surface and weight) are inputed to the system and Start is clicked on, EVERYTHING is handled by the machine, until the re-positioning of the rack itself to the drawer and its rinsing (with deionised water, which is then recycled into the electrolyte – no gold drag-out loss!), before the extraction for the next production step.

Thanks to the extremely functional, improved operative software, the sophisticated handling system accepts up to a 50% error in surface calculation, correcting and driving automatically the process in order to reach anyway the planned weight and carat values,

AUROFORM MONOLITH – WOULD YOU EXPECT MORE FROM AN ELECTROFORMING MACHINE?

NUTEC can deliver to the customer a complete series of processes, with NUFORM trade mark, that can produce different gold alloy types, in various colours, from 14 to 24 carats.

NUFORM KDF

Is a new generation of processes, with an international patent pending, based on cyanide but cadmium-free, that produce gold/copper alloy deposits from 14 up to 22 Kt, with more yellow colours if compared with gold/copper layers of the same carat.

Deposits, bright and nodule-free up to 500 µm thickness, are hard and ductile after annealing and show good solderability and mechanical resistance. The basic electrolyte is extremely stable and can support a high number of metal turnovers.

NUFORM GC

These cyanide based electrolytes produce a bright gold/copper alloy deposit, ranging from a pink 14 Kt up to a yellow-pinkish 22 Kt.

The base electrolyte has a good performance stability and the deposits obtained show good solderability, high hardness after annealing, ductility and strong mechanical resistence.

NUFORM CNF

These electroforming processes, producing 22 and 24 carat gold deposits, are 100% free from cyanides, either free or complexed, and fully comply with all international specifications on safety and health (RoHS) related to environment and operators.

In particular, NUFORM CNF 24 carat, thanks to the hardness (180-220 Vickers) and high mechanical resistance of its deposit,
unusual for a pure gold process, can be used to electroform jewellery parts.

For these particular and innovative kinds of processes, based on a special sulphite gold complex, NUTEC can give the gold solution specifications and the functional control procedure for testing it before use. If needed, NUTEC can supply the gold sulphite complex solution too, at 100 g/l gold concentration.


GOLD ALLOY ELECTROFORMING – OUR RESULT GUARANTEE PACKAGE (RGP) TURNKEY PROPOSAL

Strongly relying in the competence and experience of its professional leading team, NUTEC is proud to introduce for the first time to the jewellery market a Result Guarantee Package (RGP) proposal.

In the past years, jewellers have been trying several time to have an industrial approach on gold alloy electroforming technique but, most of the time, failed due to the lack of result driven, turnkey proposals through which the customer could be guided and supported in obtaining consolidated and guaranteed production and quality results.

NUTEC team has seriously thought at this and has decided to take this challenge!

If, despite the bad situations directly or indirectly experienced in the past, you are still willing to ascertain, with ZERO risk, that gold jewellery electroforming can be a consistent hollow jewellery production technique, please, just mail us your references and give NUTEC a chance to prove it.

After a clear definition of your needs, you will get a Result Guarantee Package proposal and decide, then, if you want to make this experience.

key

With the sole commitment of purchasing the above Package only when the previously agreed product specifications are clearly achieved, you will realize how this is true!

In one of the most advanced decorative area, “bronze age” is back!Since years, the people involved in the fashion accessories finishing are looking for valid alternatives to the materials actually used to produce objects like, for example, shoe, bag and belt complements, eyewear inserts, clothing fasteners, etc.

Depending on quality level and type of application required, brass and zinc die-cast are the core materials generally employed for their realization.
But, unfortunately, with some limitations like, e.g., major cost and more difficult workability for lead-free brass, as well as surface aspect and welding issues as far as zinc die-cast is concerned.
Without considering the specific gravity of brass, that often compels the manufacturers to alternatively use aluminium alloys, widely known as “non-easy-to-plate materials”, when, for example, bag chains and handles are concerned.

Trying to overcome these drawbacks, NUTEC has developed NOBICOT, a zinc die-cast preparation process before finishing, and NOBIFORM electroforming system, both of them object of a patent application.
The first one, born to improve zinc die-cast aspect and make it solderable, the second, addressed to control the weight of the metal parts, as in the above mentioned case, avoiding at the same time to plate aluminium alloys.

The solution proposed by NUTEC are summarized in the presentation here below.

The cyanide-free silver electroforming is possible!

We have certainly not been the first to develop cyanide-free silver plating solutions, but we are surely among the first to propose an alkaline silver electroforming electrolyte that operates at current densities comparable to those of cyanide based baths, thus maintaining a good level of industrial applicability.Being dedicated to the jewellery, decorative objects and idol markets. NUAGFORM silver electroforming process takes into account their peculiar requirements: high deposit brightness, whiteness at low current density area, good ductility at very high thickness. NUAGFORM can be also supplied in the “SF” version, producing a satin deposit with an “opalescent glaze” effect, particularly required in the production of objects like furnishings, holy images, etc., besides jewellery components.
