Leading 3D Jewelry Mold Manufacturing Techniques

Nendine uses high-end production technologies and materials in sterling silver jewelry and brass jewerlry manufacturing to produce outstanding jewelry products.

Master Wax Carving

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.

Rubber Mould

Mold making is a particularly delicate process, and Nendine 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.

Tree Wax

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.

Casting the Wax Model into Metal

01

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.

Jewelry Stone Making & Setting

02

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!

Polishing

03

After the jewelry is shaped, the metal surface and detail parts need to be further polished, and some jewelry needs a second polishing process before plating to make its surface smoother! The polishing process should ensure that the goods can not be deformed and drop stone phenomenon.

Assembly & Packaging

04

A good laser weld is three times as strong as the virgin metal, or 260 times stronger than a solder joint. This precision heat source allows laser weld metal in close proximity of heat sensitive stones and materials such as enamel and pearls, without affecting the stone or material.

We take great pride in delivering the highest possible quality to our customers.
