The models can be created from scratch or through enhancements and adaptations, in order to meet every client’s specific need.
Then we move on to the creation of the 3D model on software, in order to have the detailed 3D printing in resin or wax.
Once obtained the model to reproduce, the rubber mould have to be formed.
The creation of the brass model, is then pressed into a rubber to ensure that the shape of the model to be reproduced, remains imprinted in the rubber shape.
With extreme delicacy, the prototype is released from the rubber cast; at this point we have a starting matrix, from where the serial reproduction can begin.
Melted wax is injected inside the rubber and once it’s solidified, the wax cast is extracted; it has now become an exact and accurate reproduction of the originally designed model.
This procedure is repeated as many times as the pieces to be replicated of that particular model.
The resulted wax pieces, are welded onto an pillar in order to obtain a wax shaft.
The upright wax is then fixed to the extremity of a cylinder, ready to be filled with liquid plaster.
The liquid chalk obtained as a result of water and powder, is poured inside the cylinder.
After the drying time has passed, the chalk is now solidified and inserted in the kiln, so that the wax can dissolve and it’s replaced by the chalk mould.
In the meantime, the metal melting process is started, so it can be used for the casting.
The liquid gold is streamed into the chalk cylinders (now totally wax-less); so we wait for the cooling stage.
As regards to steel metals, the melting and casting process are executed differently.
Once the metal is melted, it’s injected into the cylinder by using the gravitational force, in order for it to reach all spaces in depth.
The next step is the cleansing of the cylinders; the shaped chalk is removed and the gold or steel duplicated tree is ready for the cutting phase.
At this point, the pieces are cut off the small tree.
The second phase of cutting involves the severing of the tiny canals that were keeping the jewels welded onto the tree.
Thanks to the sanding process, all the cutting marks are smoothed out.
The polishing phase is the last step to remove all impurities left in the product; this stage is fundamental to bringing a smooth and shiny object to perfect finish.
