The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about percent purity. The Wohlwill process increases purity to about percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution

MOULDING AND CASTING. The manufacturing process in aluminium high pressure casting takes place in two stages. These stages are called melting and casting and every single component, carrying Torun signiture on it, is manufactured by the most professional hands with expertise in the most advanced technological facility.

#0183;#32;When the liquid cools, chip off the glass which will have floated to the top during the cooling process and there is your gold, smelted to perfection. Mold the Gold. When you pour the liquid gold out of the crucible you probably don''t want it to end up in some misshapen glob on the ground so you need to have a casting dish.

Once the raw casting is clipped off from the casting tree, it has a tiny nub leftover at a place where the gold piece was attached to the sprue. The polisher grinds off this nub using the motorized grinding machine, which acts as an abrasive to smooth the surface of the gold piece/jewellery.
Centrifugal jewelry casting uses the force of a centrifuge to create the inertia necessary to throw gold into the hollow cavity left behind. After burn out, the flask is placed in a cradle on a swing arm in direct alignment with a crucible in which gold or platinum will be melted.
frequency melting and a host of other technologies, jewelry casting is more dynamic than ever. Most jewelry casting is done through the lost wax process, whereby models created through wax carving, growing, or are encased in a plaster like medium known as investment.
