The main advantage of shell moulding
is that :
A metallic pattern is used
Themoulds are stronger
Thin section can be easily obtained
High production rate is possible
High production rate is possible
Main advantage of shell moulding is
possibility of high production rate.
Hence, the correct option is (D).
&Key Points:-
Advantages of shellmouldingare :
1. Better surface finish and
dimensional tolerances.
2. Reduced post machiningresults in
high productivity.
3. Less foundry space required.
4. Can be easily automated for mass
production.
5. Complex shapes can be made as there
is no need to withdraw the pattern.
