How Levitation Melting Works with Induction Heating

Achieving minimal contamination of conductive material during manufacturing can prove to be a difficult task. One successful technique is known as levitation melting. This technique produces small quantities of electrically conductive material by suspending and then melting the material with induction heating, as induction creates a strong enough force within the coil to counter gravity. Once the material has melted, the induction power is shut off, and the molten mass can be dropped or forced into a mold for forming. With levitation not requiring a crucible, it offers a contaminant-free environment. This application is leveraged in the jewelry, dental, electronics, and aerospace research industries.

Modern induction levitation melting provides reliable, repeatable, non-contact and energy-efficient heat in a minimal amount of time. Solid state systems are capable of heating very small areas or parts within precise production tolerances, without disturbing individual metallurgical characteristics. Solid state RF induction power supplies are ideal candidates for levitation melting. Levitation melting relies on a complex balancing act involving three- dimensional forces. By using solid state equipment, consistent and reliable melting cycles are produced through accurate frequency tuning and power control.

Ambrell has offered cutting-edge levitation solutions since 1986. Our engineering expertise has been applied in many levitation melting applications worldwide.

About Induction Heating

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. The material may be a metal such as brass, aluminum, copper or steel or it can be a semiconductor such as silicon carbide,carbon or graphite. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.
