How it works
The unit uses medium frequency induction heating and is suitable for melting steel, iron, copper, aluminum, brass, bronze, stainless steel and various alloy metals.
Commonly used in small foundries, metal recycling factories, machinery processing workshops, laboratory research, jewelry smelting, hardware casting and small-batch metal smelting production. It perfectly meets the smelting demands of small-scale production, sample trial production and non-ferrous metal recycling processing.
An induction furnace melts by putting the metal inside the magnetic field of a coil. Alternating current in the coil induces currents in the charge itself, so the metal heats from the inside out and the melt is stirred electromagnetically as it forms. There is no flame and no combustion gas in contact with the metal, which is why losses and gas pickup are lower than in a fuel-fired furnace.
Frequency sets the character of the melt. Medium frequency couples efficiently into a charge of mixed piece size and gives the stirring that homogenises alloy, while higher frequency concentrates power into smaller volumes. Power supply, coil, capacitor bank and cooling are designed as one system — changing furnace size without changing the power pack is what produces disappointing melt rates.
Key features

- High Melting Efficiency & Energy Saving:
- Adopts IGBT intelligent power module, high electrothermal conversion rate, fast heating and melting speed, effectively reducing power consumption and production cost
- Stable Performance & Precise Control:
- Equipped with intelligent PLC control system, adjustable heating power and melting temperature. Electromagnetic stirring function ensures uniform metal liquid composition and stable casting quality
How to choose induction melting
- Start from the pour weight and the melt time you need, then work back to installed power; furnace capacity alone tells you the crucible volume, not the melting rate.
- Check the transformer and the supply you have. A furnace that needs more kVA than the site can deliver is a site upgrade, not an equipment purchase.
- Decide on tilt arrangement (hydraulic or manual), because it determines the pouring layout and the ladle handling around the furnace.
- Plan cooling as part of the package. Closed-loop cooling is what allows the power supply to run continuously without depending on the local water quality.

Frequently asked questions
What capacity does the Small Medium Frequency Induction Furnace handle?
20-100kg. Throughput depends on the material, its bulk density and how evenly the machine is fed, so the figure is confirmed against your material in the quotation.
Which models of the small medium frequency induction furnace are available?
4 configurations are listed on this page: TG-30KG, TG-50KG, TG-80KG, TG-100KG. The right one is set by the throughput you need and the largest piece you will feed.
How do I get a price for the Small Medium Frequency Induction Furnace?
There is no list price — every unit is configured to the material first, because the drive, chamber or coil changes with it. Send the material you process, the throughput you need per hour and the destination port, and the quotation is built on those three.
How long does an induction furnace take to melt a charge?
Installed power sets the melt rate, not the crucible size. A given crucible can be paired with different power packs and will melt at different rates, so the figure to specify is the melt rate you need in tonnes per hour and the power supply follows from it. Charge weight then sets the batch time on top of that.
Why choose induction melting over a gas or oil furnace?
Induction heats the metal directly, so there is no combustion gas in the melt, no flame impingement and far less oxidation of the charge. It also stirs the melt electromagnetically, which helps alloy homogeneity. The trade-off is a higher electrical demand and a cooling requirement that a fuel-fired furnace does not have.
