The expendable casting process is a making technique where the mold is utilized once. Once the metal has solidified, the workers crack the mold to take out the casting. There is no chance of ever using that mold.
“Expendable” is a term that refers to something that one uses and disposes of. The mold material in this instance is a waste at the end of one cycle.
This process is more desirable to industries, as it provides:
Design flexibility
Lower tolling cost
Small and medium batches
Capability to cast huge and intricate parts.
The manufacturing sector that uses this casting is in the automotive, aerospace, agriculture, construction and heavy machinery sectors.
