Permanent Mold Casting
|
|
---|---|---|
1 | Permanent mold casting molds are less costly. | Die casting dies are costly. |
2 | It requires some more floor area in comparison to die casting. | It requires less floor area comparison to permanent mold casting. |
3 | It gives good surface finishing. | It gives very fine surface finishing. |
4 | It doesn’t requires skilled labour in maintenance of mold casting. | It requires skilled labour in maintenance of die casting. |
5 | It has high dimensional accuracies. | It has very high dimensional accuracies. |
6 | This is suitable for small medium sized non-ferrous. | There is a limited scope of non- ferrous alloys and it is used for small sizes of castings. |
7 | Production rate is good. | Production rate is very high. |
8 | Initial cost is high hence it is used for large production. | Initial cost is also high hence used for large production. |
9 | Several defects like stress, surface hardness may be produced due to surface chilling effect. | This phenomenon may also occur in this case. |
