Jewelry Casting Solution
Efficient, Precise, and Reliable Casting Technology for Modern Jewelry Manufacturing
Introduction
Jewelry casting, also known as the lost wax casting process, is the most widely used method in modern jewelry manufacturing. It allows jewelers to create highly detailed rings, pendants, bracelets, and ornaments with precision and efficiency. Our Jewelry Casting Solution integrates advanced machines and systems to deliver consistent results, reduce material loss, and enhance production efficiency for jewelry factories and studios.
How Jewelry Casting Works
1. Wax Model Creation – Jewelry designs are carved or 3D printed in wax.
2. Tree Assembly – Wax models are attached to a central sprue to form a casting tree.
3. Investment & Dewaxing – The tree is encased in investment powder, then heated to remove the wax, leaving a mold cavity.
4. Metal Melting & Casting – Precious metals (gold, silver, platinum, alloys) are melted and poured into the mold under vacuum or centrifugal force.
5. Cooling & Removal – After cooling, the mold is broken to release cast jewelry.
6. Finishing – Cutting, polishing, and refining complete the final jewelry pieces.

The Workflow Of Jewelry Casting
Step 1: Wax Injection Machine
Principle: Wax is injected into a rubber mold / steel mold under pressure, forming wax models of jewelry with high detail accuracy.
Supporting Equipment: Rubber molds, chillers, wax recycling system.
Advantages:
• High precision and repeatability of wax patterns.
• Adjustable temperature and pressure for different wax materials.
• Essential for mass production of identical jewelry designs.
Step 2: Vacuum Powder Mixer (Investment Mixer)
Principle: Investment powder and water are mixed under vacuum to eliminate air bubbles, ensuring smooth and defect-free molds.
Supporting Equipment: Investment powder, mixing containers.
Advantages:
• Creates bubble-free molds for flawless casting results.
• Uniform mixing with adjustable vacuum pressure.
• Reduces casting defects and improves surface quality.
Step 3: Dewaxing Furnace (Wax Burnout Oven)
Principle: The furnace heats investment molds to remove wax and harden the plaster mold before metal casting.
Supporting Equipment: Wax collection system, exhaust system.
Advantages:
• Efficient dewaxing without damaging mold integrity.
• Precise temperature control for reliable burnout cycles.
• Compatible with different investment materials and mold sizes.
Step 4: Vacuum Jewelry Casting Machine
Principle: Precious metal is melted by induction under vacuum or inert gas and poured into preheated investment molds.
Supporting Equipment: Cooling system, inert gas supply, crucibles.
Advantages:
• Prevents oxidation and porosity during casting.
• Built-in electromagnetic stirring for uniform alloy composition.
• Precise PID temperature control for consistent results.
• Suitable for gold, silver, platinum, palladium, and alloys.
Step 5: Finishing Equipment (Optional)
Includes: Polishing machines, ultrasonic cleaners, laser marking machines.
Advantages:
• Enhances surface brightness and fine detailing.
• Enables logo engraving, serial number marking, and personalization.
• Supports high-end finishing for luxury jewelry brands.
