Professional 2000W induction jewelry casting vacuum and melting machine with digital display and plus or minus 5°C temperature precision — delivering clean, bubble-free castings of gold, silver, copper, and alloys up to 1250°C for jewelry studios and casting houses.
Key Selling Points
- 2000W Induction Heating to 1250°C (2282°F) — melts gold, silver, copper, brass, and alloys in approximately 30 minutes, with rapid and efficient heat-up for high-output casting workflows
- Plus or Minus 5°C Digital Temperature Precision — single-point digital display with LED on/off indicator maintains exact melt temperature throughout the casting process, reducing failed pours from overheating or underheating
- Vacuum Casting Ready — integrated vacuum hood and hose connections for bubble-free investment casting; requires an external approximately 2L vacuum pump (not included)
- Graphite Crucible Included — available in 1 kg, 2 kg, or 3 kg capacity; select the right size for your typical casting volume at the time of purchase
- Complete Accessory Set — vacuum hood, steel bell set, hose, rubber sole, pliers, gloves, and power cable all included; ready to connect and cast out of the box (vacuum pump excepted)
- Dual Voltage 110V and 220V — compatible with workshops worldwide, no external converter required
About This Product
The PHYHOO Digital Display Casting Vacuum and Melting Machine uses induction heating technology to deliver rapid, consistent melt temperatures with minimal oxidation. The vertical furnace design ensures even heat distribution across the graphite crucible, reducing hot spots that cause inconsistent alloy composition in the finished casting.
The integrated vacuum casting system draws air from the investment mold during the pour, eliminating porosity and surface bubbles that are common in gravity casting. Suitable for professional jewelry studios, casting houses, and small-batch custom jewelry manufacturers working with gold, silver, copper, brass, and non-ferrous alloys.
Crucible Size Selection Guide
| Crucible Capacity | Recommended For |
|---|---|
| 1 kg | Small-batch casting, individual jewelers, fine jewelry with limited metal volume per pour |
| 2 kg | Mid-volume studios, mixed alloy casting, standard production runs |
| 3 kg | High-volume casting houses, large flask casting, bulk alloy preparation |
Best For / Not For
| Best For | Not For |
|---|---|
| Professional jewelry studios and casting houses requiring precise vacuum investment casting of gold, silver, and alloys | Users without an external vacuum pump — vacuum casting cannot be performed without a separately purchased approximately 2L vacuum pump |
| Small-batch custom jewelry manufacturers working with non-ferrous metals and alloys | Ferrous metal melting — this machine is designed for non-ferrous metals only; steel and iron require significantly higher temperatures and different equipment |
| Jewelers seeking to eliminate casting porosity and surface bubbles through vacuum-assisted pouring | Environments outside 0–50°C operating temperature or above 85% relative humidity — performance and safety may be compromised outside these conditions |
| Precious metal alloying and refining requiring accurate temperature hold at specific melt points | Beginners with no prior casting experience — safe operation requires knowledge of induction melting, vacuum casting procedures, and metal handling at high temperatures |

Pro Tips
- Preheat the graphite crucible empty for 5 minutes before adding metal. This removes residual moisture and stabilizes the crucible temperature, reducing thermal shock that can crack the crucible and contaminate the melt.
- Set the target temperature 20–30°C above the liquidus point of your alloy to ensure full melt before pouring. For sterling silver, target approximately 920–940°C; for 18K yellow gold, target approximately 950–980°C. Adjust based on your specific alloy composition.
- Verify vacuum pump connection and seal integrity before every casting session. A loose hose fitting or worn rubber sole will cause vacuum loss during the pour, resulting in porosity in the finished casting. Test the vacuum hold before heating the metal.
- Inspect the graphite crucible before each use for cracks, chips, or thinning walls. A damaged crucible can fail during operation, causing molten metal spillage. Replace the crucible at the first sign of structural wear rather than waiting for complete failure.
- Ensure adequate ventilation — metal fumes generated during melting are hazardous. Operate in a well-ventilated space or under a fume extraction hood. Always wear heat-resistant gloves and appropriate eye protection throughout the melting and pouring process.
Frequently Asked Questions
Is a vacuum pump included with the machine?
No. A vacuum pump is not included and must be purchased separately. An external vacuum pump of approximately 2 liters capacity is required to perform vacuum casting. Without it, the machine can still be used for metal melting, but vacuum-assisted casting will not be possible.
Which metals can this machine melt?
This machine is designed for non-ferrous metals including gold, silver, copper, brass, and their alloys. It is not suitable for ferrous metals such as steel or iron, which require significantly higher temperatures and different equipment.
Which crucible size should I choose?
Select based on your typical casting volume: 1 kg for small-batch fine jewelry, 2 kg for mid-volume studio production, and 3 kg for high-volume casting houses or large flask work. The crucible size cannot be changed after purchase without ordering a replacement separately.
How long does it take to reach melting temperature?
The machine reaches 1250°C in approximately 30 minutes from a cold start. Actual melt time depends on the metal type, volume, and ambient temperature. Gold and silver typically reach full melt within 20–30 minutes under normal studio conditions.
Can the machine be used for metal melting only, without vacuum casting?
Yes. The vacuum casting system is optional. The machine functions as a standalone induction melting furnace without connecting the vacuum pump or hood. This makes it suitable for alloying, refining, and gravity casting workflows as well.
