Graphite Blocks for Casting Non-ferrous Metals

It's well known that artificial graphite is the most suitable element for the continuous or semi-continuous casting of non-ferrous metals, such as Copper, Aluminum,Zinc etc. Manufacturing practice suggests that using graphite block continuous casting industry, due to its great performance of thermal conductivity which decides the speed of solidification of the metal. At the same time, the size of the graphite mold with the benefits of casting precision, smooth surface, and uniform crystal structure, can be applied to the next working procedure of processing directly. The rate of qualified finished products has been enhanced, and less waste has been produced during the whole manufacturing process.

Isostatic graphite blocks and molded graphite molds are main materials that can be found in the casting production practice. Especially, while the high quality and intricate metal components are necessary to be produced according to the requirements. Through supporting on thermal stability, strength and durability required for the precise formation of metal spares, some specialized graphite molds play an important role in the manufacturing site. Normally, graphite blocks can form complex shapes and sizes to fit in special casting works because of their creation through molding process. After the graphite block has been molded, it becomes versatile and easy to be tailored while providing cost-effective results for producing intricate metal parts with excellent quality.

Graphite blocks from Xinhui Carbon can be employed in the highly efficient graphite permanent mold casting process, which is a renewed technique for improving block versatility and cost-effectiveness. This process starts with preparing the mold. Two carbon graphite blocks are fixed with a press, and molten metal is poured into the mold's gate or injection cell. After the metal solidifies, the graphite molds are separated, and the casting can be removed carefully.
