What Is Metal Casting Services

How to produce metal jewelry according to a design? Though there are a number of methods available for constructing a metal jewelry, more than likely, you would need to use a method called casting to produce the finished jewelry product.

In this process, a wax mold is used to create a piece of jewelry. This wax mold, called a pattern, is first weighed so the amount of metal required to fill the mold (stainless steel, gold, silver, etc.) can be determined. Then the mold is attached to a base, and a flask is fit over the base. Once the mold is in the flask, a kind of plaster that looks like pan cake batter called investment is mixed up, put in a vacuum to get all the air bubbles out of it, and then poured into the flask. It is then left to dry and harden. This takes a minimum of two hours.

Once the investment is dried, the base and flask are removed. Now the piece is put into a kiln to burn out the wax. Next a centrifuge is used to force the melted metal into the investment mold. Finally, the piece is cleaned up by filing and polishing it.

Sounds like a lot of work! Actually, once you learn the process, its not that difficult; however, along with some expertise, it does require some specialized equipment, so not everyone wants to go so far as to make her own cast jewelry pieces.

What, then, is the alternative? You can pay a casting service to make them for you. A casting service takes your mold and can duplicate it as many times as you'd like using a similar casting process to what I just described. Cost depends on a number of variables such as type of metal, size of the item, number of jewelry pieces you want cast, and whether you want them to be completely finished - file, cleaned, and polished -  if you plan to do that yourself.
