Our services



We utilize clear silicone molds which are in a high viscosity, liquid state at room temperature. We believe that silicone molds are the best option for fine jewelry and heavily deal with silicone molds. It is unsurpassed in the ability to pick up finite details while minimizing shrinkage.

Our silicone molds are vacuum sealed to ensure the absence of air pockets that may result in wax injections. We allow settling and curing of molds for approximately 8 hours to ensure proper setting. Our heavily experienced mold cutter then cuts the mold to ensure ease of wax injection and longevity of the mold.

Mold shrinkage is estimated as less than 1% for models.

Layered rubber molds available upon request.



Golden Century Inc has been servicing the fine jewelry industry with high quality casting for over three decades. We can cast from several different materials:

All injection waxes and hand carved waxes
3D resins from printers. We specialize in casting with Envisiontec printer resins.
Wax models from CNC Milling machines
Making molds and injecting waxes for casting

*Some 3D printer resins are subject to imperfect casts. An independent 3D printer company’s disclaimer that states their resin is “castable” differs from acceptable casting in fine jewelry standards. Individuals who submit resins that do not have an industry acknowledgement of the ability of good quality casting, submit their resins at their own risk.


Platinum? Casts Beautifully.
