Casting process include : mold making , preparation and metal smelting , pouring molten metal into a mold , cleaning castings and molds of sand recycling process . Casting product called castings or cast objects . Heavy Castings itself is different , ranging from a few hundred grams to several tons with different compositions , ranging from a few hundred grams to several tons with different compositions and almost all metals or alloys can be melted and casted .( proses pengecoran aluminium )
Casting process can be broadly divided into the casting process and the process printing . In the process pengeceron not use pressure when filling the mold cavity , while the printing process molten metal under pressure to fill the mold cavity . Because different metal filling , the mold is different , so the printing process prints are generally made of loga . In the process of casting molds are usually made of sand though sometimes also used plaster , clay , ceramic or other refractory materials .
There are two ways of casting using sand molds . The division is done based on the type of pattern that is used :
1 ) The pattern that can be used over and over again and
2 ) Disposable Pattern
The order of discussion of the casting process is as follows :
The procedure of making molds
sand ( Read: teknik pengecoran aluminium )
Equipment ( mechanical )
Pouring and cleaning of the casting .
