Leading 3D Jewelry Mold Manufacturing Techniques
The craftsman carves the wax plate by hand with reference to the design drawings. It is the most demanding process in the jewelry making process. The wax plate must be smooth and clean, the structure of each part must be reasonable.
Mold making is a particularly delicate process, and Cobaco attributes it to a science. The rubber used to make the mold will significantly affect your finished product. We can offer many types of rubber mold.
Each wax ring is individually hand-welded to a wax rod, resulting in a wax tree shaped like a large tree, ready to be cast. The wax rod must not be overfilled with wax trees, and there must be enough space between the top and bottom rows.

The wax tree is set on a stainless steel cylinder, and the plaster slurry is slowly injected along the inner wall of the cylinder, left naturally for 6-12 hours to solidify the plaster. Then, the plaster mold is baked.
Take out the baked plaster mold and prepare the metal solution for casting simultaneously. Next, the molten and prepared gold water is injected through the water spout.
According to the jewelry design drawing, diamonds or gemstones are hand sorted and picked to match the color, cut, and size, ready for setting.
Our experienced craftspeople set each diamond and gemstone by hand. Sometimes micro-setting is required, which is a skilled job, setting stones under dozens of times magnification!
