Production Process
Design and Mold Making
sdf
Original ideas are meticulously designed and hand sketched by our professional designers. These designs are then printed with a 3D wax printing machine and converted into silver molds for rubber mold making. The wax piece is then duplicated by injecting wax into the rubber molds to produce more copies of the wax jewelry.
Casting
sdf
The wax pieces are soldered onto a wax tree. Investment plaster is then poured over the wax tree and allowed to set,before being placed into a high temperature oven to create a plaster mold. Finally, the metals, which could be gold or silver, are melted into its liquid form and poured into the plaster mold. After the metal tree cools, the plaster is washed away by high-pressured water and the metal pieces are cut from the trees to prepare for the tumbling process.
Stamping and Tubing
sdf
We also carry stamping and tubing products. With sophisticated stamping and tubing molds and machines, we have the ability to produce light weight and detailed designs at a competitive price and premium quality. All of our molds are progressive molds. This allows our products to be completed within one station, ensuring high quality.
Grinding
sdf
Once the raw metal castings are clipped off from the casting tree, a small nub from the sprue that use to connect each piece with the tree will be leftover. The polisher grinds off this nub using a motorized grinding machine, which acts as an abrasive to smoothen the surface of the jewelry piece. A final polishing is then done by holding the piece against a spinning grinding wheel to achieve a smooth surface.
Tumbling
sdf
The pieces then go through the tumbling process to wash away dirt and residues.This procedure creates a smooth surface,which facilitates the sanding process later on. In order to achieve a smooth surface, we use different kinds of tumbling media inside the tumbling tank.
Stone setting
sdf
There are different types of stone settings we can produce. Different tools are used in the process of stone setting to create the desired overall effect of the piece. Stone settings vary from simple prong settings to micro pave settings, all of which are done in house.
Polishing
sdf
In the polishing process different sizes of cotton polishing wheels are used to polish the jewelries to achieve a bright shine. Our experienced workers ensure that the pieces would be left with a shine to the tiny details.
Plating
sdf
We have a selection of plating tanks that are internationally standardized. Jewelry products that require plating will be sent to this section to be plated to the customer’s needs by our professional technicians. Finished products will be tested by an X-ray machine to insure the thickness of the precious metal contents.
Packaging
sdf
A selection of packaging types are available for the finished jewelries. These packaging types include: boxes, pouches, bags, barcode stickers, stickers, care instructions, and tags. Each jewelry product will be packed as the customers requested to allow the product go from the hands of the sales to the consumers smoothly.
Final
sdf
Final QC is the last checkpoint of the factory maintained by our careful experts to inspect for any of the flaws. Our experienced staff members will check every detail as the customer requested and specifications before the products leave the factory.
