One of the most ancient known methods of fabricating metallic bodies is known as Gravity Casting. In the beginning, the metal in question is heated until it melts or in other words, it is heated to its' melting point. At that stage, solid metal turns into a molten mixture. As a gravity casting manufacturers, we pay attention to such details.
This phase does not only convert solid metal into molten solution, but it also gets rid of the unneeded impurities in the raw material. If the impurities have a higher melting point than the metal in question, they are simply discarded once the solid metal turns into molten liquid.
On the other hand, if the impurities had lower melting points than the primary metal, they turn into molten drops a lot sooner and are thus just gotten rid of. Once we have a molten mixture, it is poured into crucibles, which are basically just containers to mould molten metallic mixtures, to give them a specific shape. But unlike other processes in which high pressure gases, vacuums, and even centrifugal force are used to press the molten matter, in Gravity Casting, the gravity takes care of it all.
No outside force is applied to force the mould into a specific shape. This is one of the reasons Gravity Casting has such a long history. In those days, pressurized gases, vacuum vessels, and equipment did not exist, so they had to rely on the force of gravity.
Although steel and iron bodies frequently go through the gravity casting process, they require specialized knowledge, equipment, and machinery to do properly as they are not easy to mould into specific shapes. Other challenges facing gravity casting is the use of glass, wood, and plastic, since they have a tendency to break when temperature is suddenly increased. For this reason, the use of these materials for gravity casting is on the decline, and as days go by, the use of things like sand and tufa stone is one the rise.
