Precision Casting Technique
Lost Wax Casting — Bali Silver Jewelry
From wax model to molten silver — the lost wax casting process enables unlimited design complexity for custom and production jewelry.
Lost Wax Casting: Bali Silver Jewelry
Lost wax casting is the foundational production technique for complex silver jewelry designs. The process begins with creating a detailed wax model of the desired piece, either hand-carved by our artisans or 3D-printed from CAD files. This wax model is then invested in a plaster mold, heated to melt out the wax (the “lost wax”), and replaced with molten sterling silver cast under centrifugal force or vacuum pressure.
At Bali Silver Export, we operate one of the most advanced casting facilities in the Celuk Village area, combining traditional hand-carved wax models with modern 3D wax printing technology. This hybrid approach allows us to produce both organic, hand-sculpted designs that carry visible artisan character, and precision-engineered designs from CAD files with tolerances of 0.01mm.
Lost wax casting is the technique of choice for jewelry designs that require three-dimensional complexity, undercuts, hollow forms, or intricate surface detail that would be impossible to achieve through fabrication alone. It is also the most scalable handcraft technique — once a master mold is created, it can produce hundreds of identical pieces with consistent quality, making it ideal for wholesale production of custom collections.
Casting Process Steps
Wax Model Creation
Hand-carved or 3D-printed wax models serve as the master pattern. Hand carving preserves organic artisan character; 3D printing from CAD provides engineering precision. Both methods produce exceptional results.
Investment & Burnout
Wax models are attached to a wax tree, invested in plaster (investment material), and heated to 700°C to burn out the wax, leaving precise negative cavities in the plaster.
Silver Casting
Molten 925 sterling silver is poured or injected into the investment mold under centrifugal force or vacuum. The silver fills every microscopic detail of the original wax model.
Finishing & QC
Cast pieces are divested, cleaned, filed, and polished to final finish. Quality control checks casting integrity, dimensional accuracy, and surface quality before proceeding to assembly.
Why This Matters for Your Business
Lost wax casting offers the best balance of design freedom, production efficiency, and cost effectiveness for wholesale jewelry. Unlike filigree or granulation which are limited by hand labor capacity, casting scales efficiently — the same mold can produce 50+ identical pieces per casting cycle. This makes it ideal for brands building production collections.
For OEM and private label clients, our casting capability is particularly valuable. Your custom designs, whether created by our in-house team or provided as CAD files, can move from concept to production-ready pieces within 2–3 weeks. Master molds are stored for reorders, eliminating setup time for subsequent production runs.

Frequently Asked Questions
What is the minimum order for cast jewelry?
No minimum per design. However, casting becomes most cost-effective at 20+ pieces per design because the mold creation cost is amortized across more units. For 1–5 pieces, hand-fabrication may be more economical.
Can I provide my own CAD files for casting?
Yes. We accept STL, STEP, IGES, and 3DM file formats. Our team reviews files for manufacturability and advises on any adjustments needed for optimal casting results. CAD review is complimentary.
How accurate is the casting process?
Our casting process achieves dimensional accuracy of ±0.1mm for standard production and ±0.05mm for precision pieces. Surface detail reproduction is exceptional — fingerprint-level textures in the wax model are faithfully reproduced in silver.
What is the difference between centrifugal and vacuum casting?
Centrifugal casting uses spinning force to push silver into the mold and is ideal for heavy, solid pieces. Vacuum casting uses negative pressure and produces superior results for delicate, thin-walled, and intricate designs. We use both methods depending on the design.
How long are master molds kept?
We store master rubber molds indefinitely at no charge for active clients. This means reorders can skip the mold-making step entirely, reducing lead time by 5–7 days and eliminating the mold creation cost.
