Which of the following processes isa modified die casting process ?
-
Continuous casting
-
Centrifugal casting
-
Semi-solid metal
-
Spin casting
C
Correct answer
Explanation
Semi-solid metal (SSM) casting is a modified die casting process that reduces or eliminates the residual porosity present in most die castings. Rather than using liquid metal as the feed material, SSM casting uses a higher viscosity feed material that is partially solid and partially liquid.
