The die casting process provides complex shapes within closer tolerances than many other mass production processes. Little or no machining is required and thousands of identical castings can be produced in a very short time.
Die castings have a long service life because they are durable, dimensionally stable, and heat resistant.
Die cast parts are stronger than plastic injection molded parts having the same dimensions. Die castings can be produced with thinner wall sections that are not possible with other casting methods.
Die castings can be smooth or textured and they are easily plated or painted with a minimum of surface preparation.
Die castings offer simplified assembly by providing integral fastening elements such as bosses and studs. Holes can be cored and made to tap drill sizes or external threads can be cast
