Die casting is an
efficient, economical process offering a broader range of shapes and components
than any other manufacturing technique. Parts have long service life and may be
designed to complement the visual appeal of the surrounding part. Designers can
gain a number of advantages and benefits by specifying die cast parts.
High-speed production
- Die casting 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 before additional tooling is required.
Dimensional accuracy
and stability - Die casting produces parts that are durable and dimensionally
stable, while maintaining close tolerances. They are also heat resistant.
Strength and weight -
Die cast parts are stronger than plastic injection moldings having the same
dimensions. Thin wall castings are stronger and lighter than those possible
with other casting methods. Plus, because die castings do not consist of
separate parts welded or fastened together, the strength is that of the alloy
rather than the joining process.
Multiple finishing
techniques - Die cast parts can be produced with smooth or textured surfaces,
and they are easily plated or finished with a minimum of surface preparation.
Simplified Assembly -
Die castings provide integral fastening elements, such as bosses and studs.
Holes can be cored and made to tap drill sizes, or external threads can be
cast.
