Vacuum Induction Melting Furnace

In May 2013, US customers enquired for a vacuum induction melting furnace for precision alloy melting and established a business partnership in August.

In December 2013, the customer factory was installed and commissioned.
At present, the equipment is running well, there have been no quality problems, and a long-term relationship with customers has been established.

Vacuum Induction Melting Furnace

Model:VIM-25
Usage & Features
RVI – 25 vacuum induction melting furnace is a equipment uses the heating principle of alternating electromagnetic field produce eddy current molten metal in the metal material.
It is widely used in metallurgical industry and scientific research departments the melting and pouring of the iron-based, nickel-based, and other precision alloy, steel, special steel, high temperature alloy, non-ferrous metals, etc. under the vacuum or protective under state. The device can be realized temperature measurement, smelting, casting, cooling without destroying the vacuum state. It is a modern metallurgical equipment can produce the mold automatically.
