What's the shrinkage value of casting

Question

Accepted Answer

The shrinkage value of casting refers to the reduction in size of a casting during the cooling and solidification process.

Shrinkage occurs due to the contraction of the molten metal as it cools and solidifies.
It is an important consideration in casting design and can affect the dimensional accuracy of the final product.
The shrinkage value varies depending on the type of metal being cast and the specific casting process used.
For example, aluminum alloys typically have a shrinkage value of around 6-7%, while steel can have a shrinkage value of 1-2%.
To compensate for shrinkage, casting patterns and molds are typically designed with slightly larger dimensions than the desired final product.
