Graphite molds have been widely used in the following areas:

1、 Sintering mold
By utilizing the characteristic of minimal thermal deformation of artificial graphite materials, sintered molds and supports for transistors can be manufactured. They are now widely used and have become an indispensable material for the development of the semiconductor industry. In addition, graphite molds are also used for casting iron, durability molds for various non-ferrous metals, molds for casting steel, molds for heat-resistant metals (titanium, zirconium, molybdenum, etc.), and molds for aluminothermic welding of steel rails.
2、 Graphite molds for continuous and semi continuous casting of non-ferrous metals
In recent years, advanced production methods such as directly continuous (or semi continuous) manufacturing of bars or pipes from the molten metal state are being promoted both domestically and internationally. This method has been adopted in copper, copper alloys, aluminum, aluminum alloys, and other fields in China. Artificial graphite is considered a suitable material for continuous or semi continuous casting molds of non-ferrous metals. Production practice has proven that due to the use of graphite molds, their good thermal conductivity (which determines the solidification rate of metals or alloys) and good self-lubricating performance of the molds not only improve the casting speed, but also due to the precise size, smooth surface, and uniform crystal structure of the ingots, they can be directly processed in the next process. This not only greatly improves the yield and reduces waste losses, but also significantly improves product quality.
3、 Mold for glass forming
Due to the chemical stability of graphite material, which is not easily soaked by molten glass, does not change the composition of the glass, has good heat resistance and impact resistance, and has small size changes with temperature, it has become an indispensable mold material in glass manufacturing in recent years. It can be used to manufacture molds for glass tubes, bends, funnels, and various other shaped glass bottles.
4、 Mold for pressure casting
Artificial graphite materials have been successfully used in pressure casting of non-ferrous metals. For example, zinc alloy and copper alloy castings produced by pressure casting molds made of artificial graphite materials have been used in automotive parts and other fields.
5、 Graphite molds for centrifugal casting: Graphite molds have been successfully applied to centrifugal casting. After casting a certain number of castings, if damage is found to the inner surface of the mold, the size of the inner hole of the mold can be expanded for the casting of large shells.
6、 Hot pressing mold: Make a hot pressing mold.
The above are some areas where graphite molds are widely used, hoping to be helpful to everyone!
