Soiefleuri Jewelry Manufacturing

Every jewelry store owner wants to be successful and experience business growth. Unfortunately, the jewelry industry is such a limited and competitive industry that expansion can be difficult. Entering into a partnership with Soiefleuri Jewelry, a private label jewelry manufacturing company, allows you to gain the edge you need to succeed in such a highly competitive industry.

Wax Model

The sketched design is then carved into being, usually in special jeweler’s wax. This model must be perfect and flawless in every detail, since the final piece will only be as good as the model. The tricky thing is that during the process of turning this model into a final piece, the scale will shrink slightly, depending on the materials used. So the model maker needs to make sure that the original wax model is slightly larger than desired: but large just the right amount so that the setting and the ring, for example, will be the right size after shrinking for the stone and the finger it’s being made to fit. To help the model maker achieve perfection, there are lots of tools, including pens that precisely add wax where desired, tools that carve it away, and standard size wax molds for the band and setting basket, which can be used as is or modified.

The Rubber Mold

The original model is encased in plaster-like investment, which is specially created for jewelry making. After the investment sets, the encased wax model is burned away in an oven, leaving a jewelry shaped void in the hardened investment. That space is filled with silver, forming a slightly smaller duplicate of the original wax design, which is polished to perfection. The silver master model is then packed into a fat sandwich of special mold rubber and squeezed tight under high heat and pressure until it forms a solid block. The rubber forms itself around the master model, creating a perfect three-dimensional impression of the piece of jewelry. The rubber is cut in half to remove the silver master. Then the rubber is put back together and hot wax is injected through a hole in the rubber to fill the ring-shaped space inside, forming a wax reproduction of the master model (but a bit smaller.)

The Wax Tree

To finally turn wax into gold, a number of wax models, usually 10 or 20 are placed on a large branching wax tree. Positioning each piece on the tree must be done carefully, thicker pieces will go on the bottom, thinner on the top and the joint where the piece is joined to each branch must be positioned in a thick place in the design, where there is no detail, like the back of a ring. When the tree is complete, the whole wax structure is placed in a flask.

Pre - Polishing

First, the jewelry has to be removed from the branch, or sprue, that held it to the tree in the mold. It is then is tumbled into smoothness, sometimes sanded, lapped to make edges crisp, and then buffed by hand on a polishing wheel. Of course the final piece is checked again to make sure that no errors were introduced during the casting process. In particular, quality controllers check for any signs of porosity in the casting: little grains, voids, or bubbles that indicate that the hot gold didn’t properly fill the mold, creating a strong single unit of metal. Porosity can be an indication of weakness in the metal’s crystalline structure.
