Continuous casting is a reliable casting process for the production of high-quality semi-finished products from ferrous and non-ferrous alloys. In continuous casting, liquid metal is continuously poured into a bottomless cooled die. Inside the die, the strand shell solidifies, which is then drawn off downwards, sideways or upwards, usually with the core still liquid.

Our graphite dies and molds are designed for different casting techniques and metals. They invariably impress with their consistent material characteristics such as their thermal conductivity, chemical and thermal resistance and their high strength.
Continuous casting and semi-continuous casting
The promotion of advanced manufacturing methods such as direct continuous (or semi-continuous) manufacturing of bars or pipes from molten metal has increased in recent years, both domestically and internationally. This method has been adopted in China for the production of copper, copper alloys, aluminum, and aluminum alloys. Continuous casting or semi-continuous casting molds for non-ferrous metals are made of artificial graphite, which is considered to be the most suitable material. As evidenced by production practice, the graphite mold not only improves the casting speed due to its high thermal conductivity (thermal conductivity is a property that determines the solidification speed of a metal or alloy) and good self-lubricating performance, but also allows for direct processing in the following process due to the ingot’s accurate size, smooth surface, and uniform crystal structure. As a result, not only does the yield increase significantly, but the loss of waste products is reduced, and the product quality is significantly improved.
Pressure casting
It has been proven that artificial graphite can be used successfully in the pressure die casting of non-ferrous metals. Among other things, zinc alloy and copper alloy castings made with pressure casting molds made of artificial graphite materials have been used in automobile parts and other applications.

Centrifugal casting
Centrifugal casting has been successfully accomplished with the use of graphite molds. It has been decided in the United States to use an artificial graphite mold with a wall thickness greater than 25mm for centrifugal casting of the bronze casing. Certain anti-oxidation measures can be implemented in order to reduce the risk of artificial graphite mold catching on fire. In the event that it is discovered that the inner surface of the mold has been burned after casting a certain number of castings, the inner hole of the mold can be increased in size to allow for the casting of a large-size casing.
Glass forming
Because of the chemical stability of the stone graphite material, it is difficult to be infiltrated by the molten glass and will not alter the composition of the glass once it has been molten. The heat-resistant impact performance of graphite is excellent, and the material’s size changes only slightly with temperature. In recent years, it has emerged as an essential mold material in the glass manufacturing industry, and it can be used to create molds for glass tubes, bends, funnels, and other custom-shaped glass bottles, among other applications.
Sintering
It is possible to manufacture the sintering mold and support for transistors by taking advantage of the characteristics of very small thermal deformation of artificial graphite material. It has a long history of use. It has evolved into a critical component in the advancement of the semiconductor industry. As well as molds for cast iron, graphite molds are also used in the production of wear-resistant molds for a wide range of non-ferrous metals, as well as molds for heat-resistant metals (such as titanium and zirconium). Thermit welding molds are also used in the production of rail welds.
