Use of graphite products----Used as casting mold and moulding die

The use of graphite products is much higher than we expected, so what are the uses of graphite products we know so far?

Used as a casting mold and moulding die.

Carbon and graphite materials have small thermal expansion coefficient and good resistance to rapid cooling and rapid heating, so they can be used as casting molds for glassware and casting molds for ferrous metals, non-ferrous metals or rare metals. The castings obtained by graphite molds have precise dimensions and smooth surfaces, and can be used directly without processing or with a little processing, thus saving a lot of metal. Production of cemented carbide (such as tungsten carbide) and other powder metallurgy processes, usually using graphite materials to process dies and boats for sintering.
