Mini Gold Melting Furnace Features
- High-Purity Graphite Crucible
The high-purity graphite crucible with high density and delicate surface can heat quickly and is usually used even at a high temperature. In addition, the crucible withstands heat, acids, and alkalis to ensure dependable long-term service without wear or corrosion.
- Quartz Cover
Its lid and inner tank are made of high-quality quartz for durability. And the quartz chamber with cooling holes facilitates heat dissipation after high-temperature usage to preserve heating components.
- Digital Temperature Control
Characterized by the PID module and digital control system, the furnace monitors the melting chamber’s temperature at 2-second intervals—besides, the K-type thermocouple and display panel work simultaneously to achieve accurate temperature measurement and precise display. - Fast & Efficient Heating
The metal melting furnace with high-temperature alloy heating wire features fast & efficient heating, reaching the maximum temperature of 2102 ℉ / 1150 ℃. It can melt metals with a melting point below 1100 ℃ in 45 minutes, such as gold, sterling silver, pure copper, and aluminum.
- Complete Accessories
This gold smelter furnace set includes a graphite crucible, crucible tongs, a power cable, and protective gloves. We provide everything you need to ensure your security.
Advantages
Graphite Crucible Mini Metal Melting Furnace Advantages
- Compact Size
Mini metal melting furnaces are small and portable, making them ideal for use in limited spaces, workshops, or even at home. Their compact size also allows for easy storage when not in use. - Easy to Use

- Versatility
Mini metal melting furnaces are capable of melting a variety of metals, such as gold, silver, copper, aluminum, and more. They can handle both ferrous and non-ferrous metals, providing flexibility for different projects. - Precise Temperature Control
Many mini furnaces come with temperature control features that allow users to accurately adjust and maintain the desired melting temperature. - Cost-Effective
Compared to large industrial furnaces, mini metal melting furnaces are generally more affordable, making them an economical choice for small businesses, artisans, and hobbyists.
Structures & Working Principle
Graphite Crucible Mini Gold Melting Furnace Structure
The portable gold melting furnace is primarily composed of an insulated top cover, a top cover armrest, a graphite crucible, an insulation net, a stainless steel handle, a temperature control meter valve, a switch, and other components.
Graphite Crucible Mini Gold Melting Furnace Working Principle
The gold melting furnace’s principle is the process of instantly melting, purifying, and casting precious metals through the crucible container. It uses frequency conversion electromagnetic induction heating or induction heating for short to heat molten metal. The principle of the gold melting furnace is to convert the industrial frequency power supply into a specific frequency band power supply to heat the metal material.
