LASER AND MILLING CUTTER

 

Laser cutting is a process which, through Continuous high-precision energy propulsion, can cut silver. It is used to manufacture designs that require a high level of detail, a low thickness or very small cutting radii. It is absolutely crucial to stay abreast of the times, both in terms of quality and production speed, which is why our machines are ALWAYS ahead of their time! The simplest and least detailed items are manufactured using a milling cutter; it is a simpler process that allows us to cut down on production costs, resulting in lower prices for our customers!

ELECTROFORMING

 

Electroforming is a thick galvanic process; a characteristic of this process is that each item starts with a matrix. The matrix is the foundation of the electroforming process which takes shape through the electrodeposition of silver. A low melting point is used as a matrix to create the shape of the article and then it is dissolved by removing it from the item through the outlets.Through this process it is possible to produce empty and ultra-light items for their size.

MICROCASTING

 

Microcasting is one of the oldest techniques for making jewellery; it all starts with a 3d computer project or an existing model. A small tree is created where the “leaves” are the object to be reproduced by microcasting. Through the small tree a rubber matrix is created and when the molten silver is poured it takes the shape of the designed object. As a final step, the “leaves” are removed from the tree. Microcasting is used for small creations, for loops or spacers. It is advisable to use this technique to produce a single item that otherwise would have to be welded, again small in size.

SHEARING

 

Shearing is essentially a mechanical process. A silver plate is passed through a mould consisting of a punch and a die. The punch hits the sheet metal, enters the die and cuts the desired component through the die. It is a process that is used for mass production, has large initial costs that are easily amortized over time due to the very low unit cost.

TUBE PROCESSING

 

Tube processing is very diverse and comprehensive. Our machines allow us to cut it, corrugate it, diamond cut it, knurl it and roll it up. A tube is a basic component for the creation of other equally basic items such as beads, lugs. In many cases, tubes are used to create beads that are more durable than glass beads, and by shaping them to your liking, you can create fancy loops.

ENAMELLING

 

In order to keep up to date with the evolution of fashion, we have added enamelling to our range of manufacturing processes. Products need a fresh and colourful touch. We use the best enamels in the enamelling of our products and on top of that we apply the best protections to maximise the life of our creations.

FINISHING

 

Finishing is the process by which an item is completed. Items can be glossy, extra glossy, mirror-brushed and many other finishing options. An item that is not finished is deemed unfinished.

ELECTROPLATING

 

It’s the last manufacturing process for each item. The items are degreased by ultrasound, washed and then dipped in specific tanks to give them the desired colour. Through electroplating the metal particles are deposited on the surface of the silver giving the element colour, resistance over time and improved performance.
