Mold Making

When creating multiple pieces, jewelry molds become an essential ingredient in the production process. Numerous wax or plastic replicas of a model can be created from a mold in order to cast multiple pieces.

In addition, your model remains protected once the mold has been made. For added security, Au stores all jewelery molds in a fireproof, bank-quality vault.

In order to best serve your needs, the team at Au will work with you to determine the most effective and economical mold material for your project. Au offers three types of jewelry mold material:

1) Natural Rubber
Our Standard Vulcanized rubber mold is used in conjunction with metal models since the model must be able to resist both heat (greater than 300 degrees Fahrenheit) and pressure. Castaldo White Label rubber is the material used in production and this process is most economical when the production run is relatively large.

2) Silicone
Our Room Temperature Vulcanized (RTV) material can be used with any model made of a material that cannot withstand the heat and pressure required with Standard Vulcanized rubber molds. This would include clay, putty, and wax, as well as metal.  RTV is also a good option when production volumes are relatively low.

3) Metal
Metal molds offer more accuracy, precision, and consistency in the production process, but are also the most expensive option. Au will often recommend the use of a metal mold when a production run is quite large or if a smaller volume is extremely valuable. Our Computer Numerical Control (CNC) machine will create an aluminum mold with instructions provided by a CAD file. The pattern is produced using an injectable plastic.
