Graphite Permanent Molding is a process used for casting zinc-aluminum alloy parts and other inductrial based raw materials. Graphite is extremely stable it will not warp, twist when molten metal is poured into it for casting. Graphite mold casting technique is a modern, affordable, quick and perfect casting methodology of the new era to produce graphite molds. Aluminum alloy and special zinc-aluminum alloys can be best casted using this casting process.
Process
Graphite mold casting process is a very simple process where a plastic pieces or sheets are gathered consisting of graphite grains, pitch, carbonaceous cement, starch and a little bit of water are used for making the mold. The mixture is squeezed around the pattern and allowed to set in for a day or 2. When the mold is dried up it is put into the fire to get dry enough to form a strong mold.
For continuous casting
Graphite mold is useful for continuous casting process. In a process where continuous casting, pouring and solidification is being done non-stop with the casted product being continuously withdrawn from the open end of the mold.
Quality
Graphite a material is said to be ideal for mold making because of its overall stability that holds its shape when filled with molten metal. Because graphite do not corrode or get rusted, it has infinite shelf life. Graphite is a metal that is cheaper than steel and other metals It requires no additional heat treating and its exceptional machinability dramatically improves the mold making phase graphite mold suppliers and manufacturers try there level best to create and supply the best quality graphite mold for ideal level casting of alloys.
