Standard vacuum furnaces are available for high temperature sintering, hot pressing for powder compaction or diffusion bonding, vacuum heat treating, precision vacuum brazing, and thermal heat treatment.

These designs are augmented by specialized, custom-designed vacuum furnaces for chemical vapor deposition, Graphitization, Graphite Purification, and induction melting. These techniques and processes are used worldwide for a wide range of metal and ceramic materials at various stages during conversion from raw materials to finished product.
