METAL CASTING involves the creation of jewelry items through the melting and casting of metals.
WHAT WE DO
Our metal casters create a variety of items, ranging from rings and jewelry settings, to complete pendants, charms etc. Metals used are gold, silver and bronze.
The process of metal casting involves four (4) basic steps:
1. The process begins with the creation of a vulcanized rubber mould. This is made by taking an existing item (a ring, pendant, charm, or a blank created by carving especially for the purpose.) A rubber mould is made by setting the item in rubber and applying a vulcanizing process. This step is only required if a brand new mould is required. The club has a collection of moulds for the use of members.
2. Using a mould and hot wax, a wax casting blank is made, by injecting wax into the mould and allowing it to set. The mould is then removed and the casting cleaned and trimmed.
3. The blank is then used to create the actual metal mold by setting it in a special casting plaster called ‘investment’. Once the mould is set, the wax is baked out to clear the mold.
4. Molten metal is then used to fill the mold, either by injection of centrifugal force, and the filled mold is allowed to cool.
Once the completed casting is removed from the mold, it is then cleaned and trimmed for use as, or inclusion in, an item of jewelry.
THE CASTING WORKSHOP
Our casting workshop is well equipped, however because of the involvement of molten metal, its use is limited to club members who have been properly trained under supervision. Casting is a lengthy and involved process, and generally, casting sessions are arranged between those members who have completed training, and items are produced in batches per session.
