Comparison between Permanent Mold Casting and Die Casting

A comparison between permanent mold casting and die casting in aspects such as cost, floor area, surface finishing, production rate, and initial cost is listed below in the table form.

S.no	Permanent Mold Casting	Die casting
1	Permanent mold casting molds are less costly.	Die casting dies are costly.
2	It requires more floor area compared to die casting.	It requires less floor area compared to permanent mold casting.
3	It gives good surface finishing.	It gives very fine surface finishing.
4	It doesn’t require skilled labour in the maintenance of mold casting.	It requires skilled labour for the maintenance of die casting.
5	It has high-dimensional accuracies.	It has very high dimensional accuracies.
6	This is suitable for small to medium-sized non-ferrous.	There is a limited scope for non-ferrous alloys, and they are used for small-sized castings.
7	Production rate is good.	Production rate is very high.
8	The initial cost is high, hence it is used for large production.	The initial cost is also high; hence, it is used for large-scale production.
9	Several defects, such as stress and surface hardness, may be produced due to the surface chilling effect.	This phenomenon may also occur in this case.
