Integrated Gold Melting Furnace
Gold Melting Furnace Description
The gold melting furnace is designed for melting 1g – 12kg gold. It is also suitable to melt other precious metal like silver, copper, palladium.
Based on the latest and most advanced IGBT induction technology, the top speedy melting could be realized within 2-4 minutes. The crucible is extractable by means of matched tong.
It is the better choice for lab, jewelry shop , research institute and mining company comparing with gas melting device and resistance melting type.
We will make testing videos for each machine to ensure quality. Superbmelt also provides warranty of full refund due to bad quality within one year.

| Heating principle | Induction heating | Resistance heating |
| Power | 3.5kw | 1.7kw |
| Melting time | 2kg gold is molten within 3mins nearly | 2kg gold is molten within 20mins nearly |
| Moten metal stirring | The magnetic field will stir the molten metal to realize mixing alloy abundantly based on induction heating | No stirring function. it is by resistance heating transferring |
| Power consumption | The induction heating furnace can save over 10 times power consumption per kilogram than the resistance heating furnace | |
| Cooling system | Need water cooling | No need water cooling |
| Protection alarm | Over voltage warning, Over current warning, lack of water warning, phase loss warning, improper frequency warning | Simple working |
| Working time | Theoretically, 24 hours continuous working | After 2-3 hours working, need 30 mins stop working for cooling |
| Remark | If you have requirement about melting time and long time working, the induction gold melting furnace is the best choice. The resistance furnace is more simple and cost saving. Generally, the life time of induction gold smelter is much longer than resistance one. | |
