Welcome to Consarc

We Are Specialists in Vacuum Engineering

The first Consarc specialty furnace was developed over 60 years ago. Today, over half the vacuum or controlled-atmosphere melting furnaces around the globe bear the Consarc name.

Consarc is an Inductotherm Group company, a strategic part of one of the world’s largest groups developing technologies for the melting and processing of high-performance metals and alloys. ISO 9001 certified and with operations worldwide, Consarc is well equipped to tackle furnace projects on a global basis.

Consarc makes furnaces and related systems for vacuum induction melting (VIM), vacuum arc remelting (VAR), electroslag remelting (ESR), vacuum precision investment casting (VPIC), induction skull melting (ISM), solar silicon melting furnaces, as well as specialty furnaces for proprietary processes. All these products are distinguished by the flexibility Consarc offers in tailoring designs to customer needs.

What is


Inductotherm Group companies use electromagnetic induction for melting, heating and welding applications across multiple industries. But what exactly is induction? And how does it differ from other heating methods?

To the typical engineer, induction is a fascinating method of heating. Watching a piece of metal in a coil turn cherry red in a matter of seconds can be surprising to those unfamiliar with induction heating. Induction heating equipment requires an understanding of physics, electromagnetism, power electronics and process control, but the basic concepts behind induction heating are simple to understand.
