Application of graphite mold


Release time:


【Summary description】The application of graphite mold is very wide, mainly including the following aspects

1. Mold for glass molding: As the graphite material has chemical stability, it is not easy to be infiltrated by molten glass, will not change the composition of the glass, the graphite material has good thermal shock performance, the size changes with the temperature, etc., so in recent years, it has become an indispensable mold material in glass manufacturing, and it can be used to make glass tubes, bending tubes, funnel and other kinds of shaped glass bottles.

2. Sintered mold and other diamond sintered mold: Using the characteristics of artificial graphite material with minimal thermal deformation, it can manufacture transistor sintered mold and bracket, has been widely used, it has become an indispensable material for the development of semiconductor industry.

3. Graphite mold for continuous casting and semi-continuous casting of non-ferrous metals: In recent years, advanced production methods such as direct continuous (or semi-continuous) manufacturing of rods or pipes are being promoted at home and abroad from the molten metal state. Domestic in copper, copper alloy, aluminum, aluminum alloy and other aspects have begun to use this method.

4. Cast iron mold: Graphite mold is also used in cast iron mold, durability cast mold for various non-ferrous metals, cast steel, heat-resistant metal (titanium, zirconium, molybdenum, etc.) cast mold and welding rail with thermite welding mold.

5. Wear-resistant graphite mold: This mold is mainly used for the production of wear-resistant materials, such as silicon carbide, silicon nitride, etc.

6. High temperature graphite mold: This mold is mainly used in the production of high temperature environment, such as titanium, zirconium, molybdenum and other metals melting and casting.

Graphite mold has been widely used in many fields because of its excellent thermal conductivity, thermal stability, chemical stability, wear resistance, easy processing and other character
