COMPACT INDUCTION MELTING FURNACE

Features of compact induction melting furnace (for melting up to 5 kg of metal)

Designed for safety. The melting furnace, tilting device, and casting mold are all contained inside the unit’s box, eliminating the risk of molten metal splattering outside.
The combination of induction heating and graphite crucible enables rapid melting operation.
Our double-crucible system is designed to contain all molten metal even if one crucible is damaged and leaks. The graphite crucible can be easily replaced.
DHF high-frequency power supply unit is built with an overheating prevention timer, eliminating the risk of human error.
By using readily available standard-type graphite crucibles (commercial products), the cost of replacing crucibles is reduced.

Meltable materials: Copper, zinc, gold, silver, iron, etc.
Sample melting times: ・0.5 kg brass: about 9 mins; ・3 kg copper: about 16 mins; *The times above apply to continuous melting operation.

Features of compact induction melting furnace (for melting 10 to 30 kg of metal)

Designed for safety. The coil protection sensor is contained, ensuring safety even if molten metal leaks.
The high-frequency power supply unit is simple to operate and requires no specialized skills.
By using readily available standard-type graphite crucibles (commercial products), the cost of replacing crucibles is reduced.

Meltable materials: Copper, zinc, gold, silver, iron, etc.
Sample melting times: ・30 kg cast iron: about 40 mins; *The time above applies to continuous melting operation.
