Mold is a the key component when creating multiple pieces of jewelry. Correctly made and cut mold is the first step in jewelry production manufacturing process. At Foxus Jewellery, meticulous attention is paid to each and every stage of manufacturing. Mold-making is a particularly delicate process, and Foxus as it down to a science.
Wax Model, or sometimes called Cast or Pattern, is a replica of the final product generally produced using a preliminary material. In other terms, it is the positive of the final product where as a mold would be the negative. In jewelry applications, the preliminary material is usually wax; although, with newer rapid prototyping methods, it can be many different types of resin.
Depending on the application multiple wax patterns are created so that they can all be cast at once. In other applications, multiple different wax patterns may be created and then assembled into one complex pattern. In the first case the multiple patterns are attached to a wax sprue, with the result known as a pattern cluster, or tree; as many as several hundred patterns may be assembled into a tree.
The ceramic mould, known as the investment, is produced by three repeating steps: coating, stuccoing, and hardening. The first step involves dipping the cluster into a slurry of fine refractory material and then letting any excess drain off, so a uniform surface is produced.
The ceramic tree is then baked (stoked) at high temperatures and reaches its final strength through the sintering process. Any wax remains are burned out during this process. Before burning the investment is allowed to completely dry, which can take 16 to 48 hours. Drying can be enhanced by applying a vacuum or minimizing the environmental humidity.
