How to Choose a Gold Melting Furnace for Precious Metals
A Gold Melting Furnace is an essential machine for jewelry workshops, precious metal refiners, laboratories, casting businesses, and metal recycling companies.
The right furnace should match your metal type, batch size, power supply, melting speed, and production frequency. A furnace that is too small may reduce output, while an oversized machine may increase investment and energy use.

What Is a Gold Melting Furnace?
A gold melting furnace is a compact induction heating machine used to convert solid precious metals into molten metal.
The molten material can then be poured into molds, cast into ingots, used for jewelry production, or prepared for refining.
Unlike fuel-fired equipment, induction heating transfers energy directly into the metal charge. This improves heating speed, reduces unnecessary heat loss, and supports more accurate temperature control.

How the Furnace Works
Step 1: Prepare the Metal
The operator cleans and weighs the gold, silver, copper, tin, alloy, or precious metal scrap before loading.
Step 2: Load the Crucible
The prepared metal is placed inside a suitable crucible. The crucible should match the metal type and operating temperature.
Step 3: Start Induction Heating
The induction system generates electromagnetic heat and melts the metal quickly.
Step 4: Control the Temperature
The digital control system allows the operator to monitor and adjust the melting temperature.
Step 5: Pour the Molten Metal
After melting, the metal can be poured into jewelry molds, ingot molds, or downstream refining equipment.
Available Furnace Models
| Model | Power | Voltage | Packing Weight |
|---|---|---|---|
| 1KG | 3–5kW | 220V | 20kg |
| 2KG | 3–5kW | 220V | 26kg |
| 3KG | 7–10kW | 380V | 32kg |
| 5KG | 10kW | 380V | 38kg |
| 10KG | 20kW | 380V | 48kg |
