Understanding Induction Furnaces

Amelt is a company based in Toronto, Canada, specializing in the design, fabrication, and manufacturing of induction melting furnaces. With a focus on custom solutions, Amelt offers a range of furnaces, including copper melting furnaces, iron casting furnaces, and aluminum melting furnaces for sale. By leveraging advanced technology and expertise, Amelt aims to meet the diverse needs of industries requiring efficient and reliable melting processes [1].


Understanding Induction Furnaces

Induction furnaces are widely used for melting various metals while minimizing melt loss. These furnaces operate by transferring heat energy through a high-voltage primary coil that induces a high current or low voltage in a secondary coil. There are two main types of induction furnaces: coreless and channel [2].

Coreless induction furnaces have a refractory-lined crucible surrounded by a coil. The absence of a core allows for easy removal of the molten metal. These furnaces are commonly used for melting non-ferrous metals such as aluminum, copper, and gold. Coreless induction furnaces offer excellent temperature control and energy efficiency, making them suitable for applications that require precise melting conditions.

Channel induction furnaces, on the other hand, have a refractory-lined channel or trough that holds the molten metal. The channel is surrounded by a coil, which induces currents in the metal. Channel induction furnaces are often used for melting ferrous metals like steel and iron. They offer advantages such as high melting capacity and the ability to handle large quantities of metal.

Applications of Induction Furnaces

Induction furnaces find applications in various industries due to their versatility and efficiency. Here are five popular applications where induction furnaces excel:

1. Metal Casting: Induction furnaces are widely used in foundries for melting metals like iron, steel, and aluminum. Their ability to provide precise temperature control and quick melting cycles makes them ideal for casting applications. Amelt offers steel frame induction furnaces with a melting capacity ranging from 1 t/h to 25 t/h, catering to the needs of iron foundries [3].

2. Jewelry Making: Induction furnaces are commonly used in the jewelry industry for melting precious metals like gold, silver, and platinum. The precise temperature control and clean melting process of induction furnaces ensure high-quality metal alloys for jewelry production. Amelt provides gold melting furnaces and spare parts for induction heating equipment, catering to the specific needs of jewelry manufacturers [4].

3. Automotive Industry: Induction furnaces play a crucial role in the automotive industry, particularly in the production of cast iron and aluminum components. These furnaces enable efficient melting of metals, ensuring the production of high-quality automotive parts. The ability to achieve precise temperature control and maintain consistent melt quality is essential in automotive manufacturing.

4. Aerospace Industry: The aerospace industry relies on induction furnaces for melting and casting various metals used in aircraft components. The high melting capacity and energy efficiency of induction furnaces make them suitable for producing critical aerospace parts with stringent quality requirements.


Amelt offers a range of induction melting furnaces designed to meet the specific needs of different industries. Whether it’s copper melting furnaces, iron casting furnaces, or aluminum melting furnaces for sale, Amelt leverages advanced technology to provide efficient and reliable solutions. With applications spanning metal casting, jewelry making, automotive manufacturing, and aerospace industries, induction furnaces continue to play a vital role in various sectors where precise temperature control and efficient melting processes are essential [1][2][3][4].
