Beautifully sculpted pendants, earrings, jewelry designs, and even small sculptures wouldn’t exist if not for intricate metal casting techniques. These methods of manufacturing involve pouring a liquid metal alloy into a mold to create a jewelry piece.
There are several different types of casting methods. All involve forcing a material into a mold. The resulting part must then be polished and finished to evolve into a piece of wearable or useable jewelry.
These are some common forms of metal casting used by jewelry manufacturers:
- Lost Wax Casting: This common method of jewelry casting involves coating a waxen object with investment powder mixture. The plaster-like mixture is then fired so the wax melts, creating a hollow impression that is then filled with a molten metal.
- Sand Casting: One of the oldest methods of jewelry casting, sand casting uses natural or green sand to fill a wooden or metallized pattern. The sand is then removed, leaving a cavity that can be filled with a liquid metal.
- Continuous Casting: If you need to create casts that are identical in composition to one another, continuous casting does the job easily. A liquid alloy fills a mold on one end, solidifies instantly, and is ejected from the other end as a metal cast.
The most common method of jewelry casting is the lost wax method. Casting materials such as gold or platinum, requires specialized equipment that is designed to properly handle such precious metals at the appropriate temperatures and for the right amount of time.
Jewelry manufacturers typically rely on lost wax casting to produce silver, gold, and other precious materials within an investment powder mold. As unique as jewelry itself, different methods of metal casting yield different types of jewelry from a wide range of materials.
