1-2kg Mini Gold Melting Furnace

This compact machine requires a small water pump and a water tank to operate. Please ensure sufficient water flow and pressure are supplied to the cooling system. For clients with higher performance needs, we recommend adding a compact chiller unit (approx. $800 USD) for optimal temperature control

1kg-2kg Induction melting furnaces are highly efficient, typically requiring only 2-3  minutes to melt a full batch. In contrast, traditional resistance wire heating furnaces may take over 40 minutes to reach the same melting temperature

This Small Furnaces of this class typically reach a maximum temperature of 1250°C. In addition to gold, they are well-suited for melting non-ferrous metals such as silver, copper, and aluminum, and are also applicable for small sample testing in laboratory settings

A: Yes. High-quality 1-2kg induction furnaces are equipped with an advanced cooling system designed specifically for 24/7 continuous operation, making them ideal for demanding, high-intensity production environments.

Yes, it's a true desktop solution. With a main unit weight of around 20kg and a compact footprint, it saves significant space. Running on a standard single-phase 220V outlet, it's the perfect, versatile power source for small jewelry shops, on-site gold sampling, or even home studios.

The operation is quite straightforward. The equipment is typically equipped with a digital control panel and temperature monitoring devices (such as thermocouples), allowing users to observe temperature changes in real time. It can be operated with minimal technical training

None. Our mini induction furnaces feature contamination-free heating and graphite crucibles to protect your metal. Plus, automatic electromagnetic stirring ensures perfectly uniform alloys.

Absolutely. Induction heating is much safer—no open flames, and the heat is focused inside the metal, so the outside stays relatively cool. Plus, it comes with built-in safety alarms for issues like power surges, low coolant, or overheating, giving you peace of mind.

This is typically related to the cooling water system. In over 90% of cases, the cause is blocked water pipes (due to scale buildup from poor water quality) or insufficient water pressure. When the outlet water temperature exceeds approximately 79°C, the safety switch will automatically cut power to protect the induction coil from damage

Under normal operating conditions, the service life of a graphite crucible is typically 30 to 50 melts. For maintenance, it is recommended to preheat the crucible to between 300°C and 400°C before its first use to remove moisture, and to avoid subjecting it to severe mechanical shock when it is in a hot state

Yes, water quality is critical to the longevity of the induction furnace. To prevent calcium deposits from building up inside the induction coil or heat exchanger—which would reduce cooling efficiency—it is strongly recommended to use clean, circulated water or deionized water

A: The choice depends on your needs:
Choose an mini induction furnace if: You prioritize speed, require long-term continuous operation, and have the budget. It offers far superior energy efficiency and a longer operational lifespan.
Consider a resistance gold melting furnace if: You only perform very small, infrequent melts occasionally and are highly cost-sensitive. It can be a suitable entry-level option under these specific conditions.
