The Arcast Inc Mini Vacuum Arc Melter offers the ability to melt, cast and rapidly solidify metal alloys of nominal 200 gram mass using a clean ceramic free cold crucible process. It offers the ability to melt and alloy metals at over 3000 Deg. C, such as titanium alloys, memory alloys and bulk amorphous glass alloys. The furnace is enclosed in a stainless steel vacuum chamber and offers many standard options. The standard options include:

There are also two vacuum options: medium (1E-2 mbar) and high (5E-6 mbar). All options are designed for quick cycle times and user friendly operation.

The intended use for the Vacuum Arc Melter is to allow metallurgists and technicians to alloy reactive or nonreactive metals, and cast or atomize these alloys with the least running cost and capital cost, while maintaining a high engineering standard.

Our Arc200 is highly flexible and configurable

Below are some of the options available (select the schematic drawings to see larger views)

Electromagnetic stirring

We have added a highly effective electromagnetic stirrer to our range of options for our arc melters. This allows complete alloying in one heat cycle without the need to flip and re-melt multiple times. It works with any alloy system and comes in many different specifications to modulate the amount and type of stirring as required.
