Graphite mold

Graphite is widely used as material for continuous casting molds. Ingot graphite molds are commonly used in copper casting, aluminum casting, gold casting, and silver casting.

Graphite mold casting technique is a modern affordable, quick and perfect casting methodology to produce graphite molds. Graphite mold is useful for continuous casting process. In a continuous casting process the pouring and solidification go non-stops with the casted product being continuously withdrawn from the open end of the mold.

Main application:

Application of hot bending graphite mold

The screen of intelligent terminal production has become one of the critical factors for consumers in choosing mobile phone. With the improvement of consumers’ requirements towards the product appearance and the performance of intelligent terminal production, the related product screen has been gradually transforming from flat touch screen to 2.5D surface and 3D touch surface. Curved glass has advantages such as thin and light, transparent and clean, fingerprint resistant, anti-glare, and good weather resistance. The curved glass can not only enhance the intelligent terminal product appearance’s innovation, but also bring out good touch feeling and excellent performance, which makes the curved glass become the first choice for smart phone, the vehicle instrument panel, smart watch and other devices.

Graphite hot bending mold is mainly used in the process of bending the plain glass into curved glass under high temperature condition. Because of the complicated processing and the high cost of the graphite molds for glass, high-end graphite with fine grain size, high density, and high strength must be purchased in order to ensure the service life of the mold and the quality of glass.



Graphite ingot mold application in electronic and semiconductor industry
