Graphite is used in melting, casting and shaping of precious metals such as gold and silver, as well as in many areas due to its resistance to high temperature and thermal shocks.
The process of solidifying the melted metal in the chamber in a certain cross-section with the help of a mould by cooling the area where solidification begins is called continuous casting process.
With the widespread use of CNC machines, moulds of precious metals such as gold and silver, which were made by hand engraving in the past, can be manufactured in a much shorter time.
The chamber used in the melting of non-ferrous metals is called a crucible.
Due to its softness, it is used in pencil making and lubrication of moving metal parts, and due to its resistance to fire and acids, it is used in casting and refractory industry, crucible and laboratory materials.
Graphite, which has a crystalline structure just like diamond due to the carbon in its structure, is still a very soft material that cannot be compared to diamond in terms of hardness.
Especially preferred in the moulding sector, the process of shaping the workpiece by arc method by applying electric current to the conductive material is called plunge erosion method.
Despite the difficult and fluctuating economic conditions of the 1970 - 90 period, MEGA (Schmidthammer Elektrokohle GmbH) regularly followed the developments in accordance with the technology of the day and realized the carbon-graphite raw material proces
