gear manufacturing methods
Can someone here (preferably from mechanical engineering background) tell me why we can not use cast iron for die-casting?

ShrinkDWorldI think we have better material than C.I.
So that it is more useful -
jyotimoon09this in not a proper answer.
please justify your answer -
jyotimoon09please give me a proper answer because i have to submit assignment on this question.

gohmAlthough you can cast iron via methods like sand and foam, it does not lend itself well to die casting due to the properties of iron. Highly fluid Non-ferrous alloys work much better for high pressure mold injection. Die casting also has thickness and weight limitations which also makes iron less than ideal.

070790viveki think gohm is right
die casting needs some special faetures for better moulding
i think that for mass production we use cold die casting
and the %of carbon present in C.I. creates some problem in such a very less time for moulding and it has to face high pressure -
saimriyazdue to its properties............

RVigneshCI is best suited where there is compressive forces only , but in case of die casting there are other forces also . Moreover the actual materials used for die casting like Zn etc have properties a lot different from CI hence the other materials are better suited and CI is not used

sumit guptabcoz cast iron is brittle material thats why it can not use fr die casting

TejaNaiduwe can use cast iron for die casting.But it gives less strength when subjected to compressive forces and poor characterstics in matarial...thatsway we cant.
