Die casting process is a manufacturing process for producing accurately dimensioned, sharply defined, smooth or textured surface metal parts. It is accomplished by injecting liquid metal at fast velocity and under high pressure into reusable steel dies. Compared to other casting processes, die casting is at the top end of both velocity and pressure. The high velocity translates into very turbulent flow condition. Die Casting process is often described as the shortest distance
between raw materials and the finished product. the term die casting is also used to identify the cast product.Comparison between Permanent Mold Casting and Die Casting
The comparison between permanent mold casting and die casting in aspects like cost, floor area, surface finishing, production rate, initial cost are listed as under 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 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.
