Gold Melting Furnace for Precious Metal Casting
A Gold Melting Furnace is an essential machine for jewelry workshops, precious metal refining plants, metal casting factories, laboratories, and recycling businesses. Gold, silver, copper, tin, and precious metal alloys require accurate heating, clean melting, fast operation, and stable temperature control.
For small and medium-scale precious metal processing, traditional melting methods may be slow, inconsistent, or difficult to control. Operators need a machine that can heat quickly, save energy, reduce manual work, and support repeatable melting results.
The WOLFU Gold Melting Furnace is a compact induction melting system designed for 1–10kg precious metal melting. It can melt gold, silver, copper, aluminum, tin, and precious metal alloys within minutes while maintaining precise digital temperature control.
What Is a Gold Melting Furnace?
A gold melting furnace is a metal melting machine used to heat solid gold or precious metal scrap until it becomes molten metal. The molten metal can then be poured into molds, cast into ingots, refined, or used for jewelry production.
The WOLFU gold melting furnace uses induction heating technology. Instead of heating the metal only from the outside, induction heating generates electromagnetic energy that heats the metal charge quickly and efficiently.
This makes the machine suitable for users who need fast melting speed, compact equipment size, simple operation, and stable thermal performance. It is especially useful for jewelry manufacturers, small foundries, precious metal recycling companies, and laboratory metal testing applications.
Depending on the model, the furnace capacity can range from 1kg to 10kg. This allows customers to choose a suitable machine based on batch size, workshop space, power supply, and production frequency.
Why Induction Heating Is Suitable for Precious Metal Melting
Precious metal melting requires speed and precision. Gold, silver, and precious metal alloys are valuable materials, so operators need to reduce material loss and avoid unstable melting conditions.
Induction heating provides several practical advantages. It can heat metal rapidly, reduce waiting time, improve energy efficiency, and support better temperature control compared with many conventional heating methods.
For jewelry workshops, fast melting helps improve production efficiency. For refining plants, stable melting helps prepare materials for downstream refining or casting. For laboratories, digital temperature control helps improve repeatability in testing and sample preparation.
Because induction melting equipment is compact and relatively easy to operate, it is also suitable for businesses that need flexible production without a large furnace installation.
How the WOLFU Gold Melting Furnace Works
Step 1: Preparing the Metal Material
The process begins by preparing the metal charge. Suitable materials include gold, silver, copper, aluminum, tin, precious metal alloys, and precious metal scrap.
Before melting, operators should remove visible impurities, non-metallic materials, and unsuitable foreign objects. Cleaner feed material helps improve melting quality and protects the crucible.
Step 2: Loading the Crucible
The prepared metal is placed into the crucible. The crucible holds the metal during heating and melting. The correct crucible type should be selected according to the metal material and operating temperature.
Proper loading is important. Overloading the crucible may cause safety risks or reduce melting efficiency. Underloading may reduce production efficiency for larger batches.
Step 3: Induction Heating
After loading, the induction system begins heating. Electromagnetic induction generates heat in the metal charge, allowing the material to melt quickly.
The WOLFU furnace can melt metals in approximately 3–5 minutes depending on the model, metal type, batch size, and operating conditions.
Step 4: Digital Temperature Control
The furnace is equipped with a digital control system. Operators can adjust and monitor the melting temperature more easily, which helps maintain process consistency.
The maximum working temperature can reach 1450°C, making the machine suitable for melting common precious metals and selected non-ferrous metals.
Step 5: Pouring and Casting
After the metal is fully molten, it can be poured into molds, cast into ingots, or used for downstream processing. Careful pouring helps reduce material loss and improves casting quality.
For jewelry production, molten metal may be used for rings, ornaments, pendants, and custom parts. For recycling and refining, molten metal may be cast into bars or prepared for further purification.
Key Advantages of the WOLFU Gold Melting Furnace
Fast 3–5 Minute Melting Speed
One major advantage of the WOLFU induction furnace is fast melting. The machine can melt metal within 3–5 minutes under suitable operating conditions.
Fast melting helps reduce waiting time and improves workshop productivity. This is useful for businesses that process multiple small batches each day.
1–10kg Capacity Options
WOLFU provides several capacity options, including 1kg, 2kg, 3kg, 5kg, and 10kg models. This allows customers to select the right machine for their actual production needs.
A jewelry workshop may only need a 1kg or 2kg unit. A precious metal recycling or casting business may prefer a 5kg or 10kg model for larger batches.
High Temperature Capability
The maximum working temperature can reach 1450°C. This temperature range is suitable for melting gold, silver, copper, aluminum, tin, and many precious metal alloys.
High temperature capability gives users more flexibility when handling different metal materials.
Digital Temperature Control
Digital temperature control allows operators to manage the melting process more accurately. Better temperature control helps improve repeatability and reduces unnecessary overheating.
For valuable precious metals, stable temperature management is important because it helps protect material quality and improve casting consistency.
Compact and Portable Structure
The WOLFU gold melting furnace has a compact machine structure. The listed machine dimension is 870 × 355 × 400 mm, with model weights ranging from 20kg to 48kg.
This makes the equipment suitable for jewelry workshops, laboratories, small casting rooms, repair shops, and small-scale precious metal processing businesses.
Energy-Efficient Induction Design
Induction heating transfers energy efficiently to the metal charge. This can reduce unnecessary heat loss and support stable operation during melting.
For users who melt metals frequently, energy-efficient equipment can help reduce long-term operating cost.

Digital temperature control helps improve process repeatability for experimental use.
Precious Metal Recycling
Recycling businesses can use the furnace to melt precious metal scrap into ingots or molten material for easier storage, transportation, and downstream refining.
How to Choose the Right Gold Melting Furnace
The first factor is melting capacity. If you process very small jewelry batches, a 1kg or 2kg model may be enough. If you handle larger batches of precious metal scrap, a 5kg or 10kg model may be more practical.
The second factor is power supply. Smaller models can use 220V, while larger models usually require 380V. Buyers should confirm local voltage before ordering.
The third factor is metal type. Gold, silver, copper, aluminum, tin, and alloys may have different melting temperatures and operating requirements. The furnace model should match the material you process most often.
The fourth factor is working frequency. Occasional laboratory use is different from daily workshop production. Frequent use may require stronger configuration and better cooling support.
The fifth factor is downstream process. Jewelry casting, ingot casting, refining, and recycling may require different crucibles, molds, accessories, and workflow layouts.
