Juyi Automatic Vacuum Casting Machine – Precision Casting for Precious Metals

The Juyi Automatic Vacuum Casting Machine, also known as the Gold and Silver Vacuum Casting Machine or Precious Metal Automatic Vacuum Casting Machine, is specially designed for high-quality lost wax casting of gold, silver, copper, and other precious metals. It is widely used in jewelry foundries, Buddha statue foundries, and metal handicraft manufacturing, meeting the stringent requirements of the lost wax casting process.

Key Features & Advantages:

1. Integrated Melting and Casting for Superior Quality
Unlike traditional systems that separate melting and casting processes, the Juyi machine combines both in one unit. This integrated design avoids metal oxidation during transfer, shortens processing time, and ensures casting is performed in a completely vacuum environment, significantly improving the density, surface smoothness, and overall quality of the final product.

2. Large Casting Chamber in a Compact Design
Thanks to an efficient structural layout, the machine offers a larger casting space within a compact footprint. This allows more metal to be cast per cycle, increasing production output without taking up more factory space.

3. Independent Melting and Casting Chambers
While melting and casting occur within the same machine, the melting and casting chambers are physically separated. Once melting is complete, the bottom seal of the melting chamber opens automatically, allowing the molten metal to flow into the casting chamber. This separation eliminates cross-contamination and ensures consistent casting results.

4. Powerful Magnetic Stirring System
Equipped with induction stirring technology, the machine stirs the molten metal using electromagnetic force during the melting process, ensuring the alloy is completely uniform and enhancing the quality of the casted product.

5. User-Friendly PLC Touchscreen Operation
The machine features a PLC touchscreen control panel, which supports customizable language options based on client needs. Operators can switch between manual and fully automatic modes. In automatic mode, once the parameters (melting time, vacuum time, casting time) are set, the system can start with one click and proceed through the entire cycle automatically — improving operational efficiency and reducing the chance of human error.

6. High Efficiency with Energy-Saving Design
Using advanced IGBT induction heating technology, the furnace can reach 1600°C within minutes, achieving melting times of 3–5 minutes per batch. Compared to traditional methods, it can reduce energy consumption by 15–30%, helping lower overall casting costs.

7. Precision PID Temperature Control
The system uses a PID temperature control unit, maintaining temperature tolerance within ±2°C. This ensures precise heating, which is critical for alloy stability and casting accuracy.

8. Full Safety Monitoring System
Built-in safety protections include alarms for overheating, overcurrent, short circuit, water shortage, and frequency anomalies. The system automatically shuts down in case of abnormalities, protecting both operators and equipment.

9. Customizable Configurations
The Juyi casting machine is equipped with a 15kW induction power supply, supporting metal capacities from 1kg to 6kg (gold equivalent).

• Automatic and semi-automatic modes are available.

• Melting and casting chamber sizes can be customized to suit your specific product dimensions and production capacity.

• We also support custom automation levels and interface languages depending on your factory’s workflow.

Whether you are a jewelry manufacturer, alloy developer, or artisan crafts producer, the Juyi Automatic Vacuum Casting Machine is a powerful solution to improve product quality, enhance efficiency, and reduce production costs — all while supporting a cleaner and safer working environment.
