Hi, this is a multiple question based question.
00:04
So, here we have in the first question we have to find the purpose of annealing of glass in glass working.
00:13
So, this is done for remove the internal stress.
00:17
So, for removing the internal stress internal stress also to soften the glass soften the glass and for increasing the toughness.
00:34
So, this is the process of annealing or this is the use of process of annealing in glass working.
00:42
In the next part we have to find the expandable mould casting process.
00:57
So, here it is done for sand casting.
01:04
So, sand casting and shell casting and investment casting, casting and investment casting and the last is so, this is casting and vacuum casting.
01:33
In the next part of the question we have the advantage of so, advantage of die casting over.
01:44
So, die casting over sand casting.
01:50
So, the reason is for better surface finish and accuracy finish and accuracy then we have we can have more complex geometry can be casted can be casted...
