Jewelry Silicone Mold Making

Custom silicone and vulcanized rubber molds for wax injection — scale from prototype to mass production with consistent quality.

Production Molds for Jewelry Manufacturing

Once you have a finished master model — either a polished casting or a high-detail 3D print — we create a silicone or rubber mold around it. The mold lets you produce identical wax copies for casting, over and over. One mold can produce hundreds or thousands of wax injections before needing replacement.

This is the bridge between prototyping and production. Instead of 3D printing every wax model individually, you invest once in a mold and then produce waxes at a fraction of the cost and time. We cut the mold by hand along optimal parting lines to ensure clean wax extraction without damaging fine detail.

Mold Types

We match the mold type to your production needs and design complexity.

Vulcanized Rubber

Heat-cured rubber molds for high-volume production. Extremely durable — handles thousands of wax injections. Best for designs without heat-sensitive stones or delicate undercuts.

RTV Silicone

Room-temperature vulcanizing silicone for delicate masters. No heat involved, so safe for models with pre-set stones or temperature-sensitive materials. Excellent detail reproduction.

Multi-Cavity Molds

Multiple copies of the same design in a single mold frame. Speeds up wax injection for high-volume orders. Consistent sizing across all cavities.

Multi-Size Molds

Same ring design in multiple sizes within one mold. Common for production lines that need to stock a range of sizes from a single design.

Complex Parting Lines

Designs with deep undercuts, moving parts, or intricate geometry need expertly planned parting lines. We cut by hand to ensure clean wax release without tearing.

Mold Repair & Duplication

Worn out mold? We can duplicate it from an existing wax or casting. We also repair damaged molds when the master model is no longer available.

From Master to Mold to Wax

A straightforward process that turns one model into unlimited production copies.

1

Prepare the Master

Your master model is cleaned, polished, and inspected. Any surface imperfections on the master will transfer to every wax copy, so we make sure it's flawless before molding.

2

Make the Mold

The master is embedded in rubber or silicone, then cured (vulcanized or room-temperature depending on type). The mold is cut open along planned parting lines.

3

Wax Injection

Hot wax is injected into the mold under pressure, cooled, then carefully extracted. Each wax copy is inspected and ready for casting. The mold is reusable for thousands of injections.
