The use of casting is to form a hot liquid metal or many metals, cooling after mixing components such as clay, gypsum, concrete and poxies.Since other methods are not feasible, complex shapes are usually made by casting.Casting was born about 6000.Copper foam is the oldest casting since 3200 BC.
There are two different branches in the casting process: non-Mold casting for consumables and consumables.x91Non-Expendable mold casting: This technology includes at least 4 different methods of continuous, centrifugal, mold and permanent casting.Continuous casting: continuous casting can be defined as the refining process of casting forhigh-Volume, continuous production of Constant metal profilessection.
Pour the molten metal into the watercooled, open-Endedcopper mold.This allows the formation of a solid metal cladding above the rest-liquidx92 center.Continuous casting due to its cost-effectiveness.
The continuously cast metal has aluminum, copper and steel.Centiugal casting: centrifugal casting has nothing to do with the following twoPressure and gravityThis is because its own force feedback is generated by using a temporary sand mold in a rotating chamber of 900 N.The lead time is different relative to the application.
True-and semi-Centrifugal processing allows 30 to 50 pieces/hour.The upper limit for batch processing is about 9000 kg (actually ).This method was used in the casting of railway wheels.
It has also been made by a family named rakkrupp.It originated in Germany.Jewelry is usually cast in this way.Die-Casting: die casting can be defined as the process of pushing the molten metal into the cavity of the mold at high pressure.These castings are made of non-ferrous metals, in particular-Alloys of aluminum, copper and zinc.
It is even possible to make metal die castings.Use the die casting method where finer parts are needed.Permanent casting mold: This casting is made by non-ferrous metals.
It takes some time to set up (a few weeks) and then about 5 to 50 pieces/hour productivityMoldis is implemented.Acetylene soot coating is applied in the steel cavity.This helps to easily remove the workpiece and improve the service life of the (tool.
The life of the permanent mold is limited.For worn molds, replacement or repair is required.Consumable mold casting: consumable mold casting can be called Standard classification, including the following: sand casting: it is one of the simplest and most popular casting types since use.
It is very small in size.
The combination of sand is achieved by the use of clay, such as green sand, or by aggregate oil or a chemical mixture.Recycling is easy to implement.Gypsum casting (for metal): There is no difference between gypsum casting and sand casting except that gypsum replaces sand.Also, there are plastic and concrete castings.
