Why Partner with HarperCrown
Manufacturing Process A-Z
Collaboration & Design
To get started, please fill out our Custom Jewelry Manufacturing Form below. Once submitted, one of our representatives will reach out. During your consultation with our team, we will ask several questions and ask for a drawing/sketch of your design. We will cover all aspects of your design from material, measurements, quantity, and any finish requirements. Once we have all the pertinent information we will begin the CAD design process. We will design your item and send a photo of the master for your approval. Once we have your approval we can move on to the production process.
If you already have a CAD or 3D print that's great. We can head directly to the production process.
Mold, Wax, & Investment
There are several ways of creating a mold but the most common are rubber and metal molds. The mold will ensure the intricacies of your design are kept throughout the casting process.
Once we have the mold we will shoot wax into the mold and attach to a tree which will placed into an investment. Once the investment material has settled, the flask will be then placed into a burning kiln which helps burn away the wax leaving behind a cavity that works as the final mold for the jewelry piece. The wax melts out through a couple of sprues that are attached to the bottom of the mold before placing it in the kiln. The number of sprues depend on the size of the piece of jewelry. This is also called the burn out cycle in which wax models are connected to each other using a sprue forming a tree-like formation. This formation is then put into a metal flask which is filled with a slurry of plaster. The flask is then debubblized to get rid of any air bubbles or air pockets in the mold. Once the wax has melted away and the mold has been invested leaving behind no remaining wax residue and only a hollow impression to serve as a mold for jewelry, it is time to pour in the metal of your choice.
Casting
Your choice of metal is melted at a high temperature and poured into a flask for it to funnel through intricate cavities before it cools. Once the metal has been poured, it is allowed to cool down for a few minutes before being dunked into cold water to retain its final shape. The amount of time required for the cooling process depends on the type of metal that is being used and its melting point.
Next, the jewelry is polished by using a buffing wheel to give the piece a shiny, complete finish. Buffing machines, enamel clothes, polishes and filers can be used to the give the final piece the desired shape and style.
Inspection & Shipping
Finally, if required, your piece will go into plating. We offer several different color finishes: yellow, rose, silver, and black rhodium. Our plating is nickel free which avoids any allergic reactions.
All of our jewelry are quality inspected for imperfections. This is to ensure we give you our best work. Once the pieces pass our inspection the pieces are ready to ship.
