Production Techniques

ELECTROFORMING

ELECTROFORMING

Electroforming is a technique that has been used by TOUS for more than 20 years, the result of a large investment into innovative new technologies. It allows for the creation of larger, lightweight, quality pieces without the need for soldering. Through a chemical electrolysis process, the particles of precious metal are deposited on a base, which is removed once the piece of jewelry is finished. Only 18 kt gold (750/000 gold) and sterling silver (925/000 silver) is used to create designs from 180 microns thick for gold and 300 microns for silver.
CASTING

CASTING

Casting is the most frequently used method in TOUS’ workshops and in the jewelry industry in general. A liquid wax is injected into a rubber mold and, once cold, is covered with plaster. Then, the plaster cast is placed in a centrifuge where metal, usually gold or silver, is injected to replace the wax, creating the desired piece of jewelry.

SINTERING

The sintering process is suitable for pieces with complex shapes. It consists of a laser that melts thin layers of metal powder to create a digitally designed figure. The programme divides the 3D design into layers and a moving arm lays a thin layer of atomised metal powder on a platform, while a laser melts the areas where the 3D marks what should be part of the piece. The arm then passes through again to deposit another layer of powder, and so on until the final piece is created. This technique is limited by metal. Only gold, titanium and platinum can be sintered. Collections such as Real Sissy and some Teddy Bear bears have been created using the sintering process.

MACHINING

There is a multitude of different machining processes and techniques that enable jewellery to be made quickly and easily, although they always require a skilled artisan for the perfect finish.

Stamping

This is one of the most-used techniques at TOUS. It consists of applying pressure to thin sheets of metal using dies marked with the desired design or shape. This is how the pieces in the Nenúfar collection were created.

Numerical control milling machine

Sometimes there are volumetric pieces that cannot be created by stamping because of their shape. In these cases, we use the numerical control milling machine, which sculpts the piece in two dimensions using a metal plate. The Camille collection is an example of pieces created using the CNC (Computer Numerical Control) process.

Waterjet cutting and laser cutting

To cut out shapes in thin sheets, waterjet and laser cutting techniques are used. While one uses a pressurised jet of water for cutting, the other is cut directly with a laser. These are common processes in our collections, such as the gold Minne and the Sketch Line bear.
