Better surface finish with the close dimensional tolerances of the casting can be obtained in gravity die casting.

Better surface finish with the close dimensional tolerances of the casting can be obtained in gravity die casting. Correct Answer True

In gravity die casting, a fined-grained casting with good surface finish of the order of 4 microns can be produced. Close dimensional tolerances can also be obtained and with a better appearance of the casting. It is also economical for large scale production as the labour involved in the mould preparation is reduced.
