1、GRAPHITE: Graphite mold is made of graphite material, which does not affect the purity of the metal, and the hot and cold conditions are fast to create a delicate refining effect. 2、WITHSTAND HIGH TEMPERATURE: Graphite mould has high thermal stability and can withstand a maximum temperature of 2000℃, enabling you to work in more situations. 3、HIGH USAGE: Graphite ingot mould has a high performance, can do shortening melting timing and saving energy, so that you can put limited material to more use. 4、IMPACT RESISTANT: Rectangular graphite mold has high impact resistance, acid and alkali corrosion resistance. Excellent performance, safe and reliable. 5、WIDELY USED: Graphite mould is suitable for experiment or melting of gold, silver, brass, copper, aluminum, zinc and other metals, and can also be applied as an aid for making pendants or other analytical tools.
