The casting process includes mold making, metal preparation, and smelting, casting of molten metal into molds, casting and mold recycling process. The casting product is called castings or cast objects. The weight of the castings itself is different, ranging from a few hundred grams to several tons with different compositions, ranging from several hundred grams to several tons with different compositions and almost all metals or alloys can be melted and cast, then it will become a plaque.
The casting process, in general, can be distinguished in the process of casting and printing process. In the process of the retailer, no pressure is used when filling the mold cavity, while in the process of molding molten metal is pressed to fill the mold cavity. for more info you can visit http://www.award.com
There are two ways of casting by using sand molds. The division is done based on the type of pattern used:
- 1) Patterns that can be used over and over and
- 2) Disposable patterns
The order of discussion of the casting process is as follows:
Mold making procedure
Pouring and cleaning casting.
PROCEDURE OF MOLD MAKING
Prints are classified based on the materials used:
Wet sand molds (green-sand molds)
Dry skin mold (Skin dried mold)
The mold is made of coarse sand with a binder
Molds (Loan molds)
Mold furan (Furan molds)
Metal molds Metal molds are mainly used in a metal die casting processes with low liquid temperatures.
Special molds Special molds can be made of plastic, paper, cement, plaster, or rubber.
The molding process carried out in the foundry factories can be grouped as follows:
Making mold on the table (Bench molding)
Done for small cast objects.
Molding on floor (Floor molding)
Performed for medium or large cast objects
Making mold pits (pit molding)
Making mold with machine (machine molding)
The mold is made in print (plaque) consisting of two parts, the upper part is called the coup and the bottom is called drag. Pack a box consisting of three parts, the middle part is called cheek. The two sections of the mold box are joined to a specific place with holes and pins.
