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.

Steel Mold 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)
