Forgings
Compared with forgings, die casting can be more complex in shape and
have shapes not forgeable, can have thinner sections, be held to closer
dimensions, and have coring not feasible in forging.
Plastic Injection moldings
Compared with plastic injection moldings, die casting are stronger,
stiffer, more stable dimensionally, more heat resistant, and are far
superior to plastics on a properties/coat basis. They help prevent
radio frequency and electromagnetic emissions. For chrome plating, die
castings are much superior to plastics. Die castings have a high degree
permanence under load compared to plastics, are completely resistant to
ultra-violet rays, weathering, and stress-cracking in the presence of
various reagents. Manufacturing cycles for producing die castings
are much faster than for injection moldings.
Extrusions
Compared to extrusions, die casting can be produced faster and more
net shape. Features and depressions on the sides, tops and bottoms can
be created in one operation. There is less waste using die casting than
extrusion. Holes can be cast in place to save additional machining
cost.
Stampings
Compared with stampings, one die casting can often replace several
parts. Die casting frequently require fewer assembly operations, can be
held within closer dimensional limits, can have almost any desired
variation in section thickness, involve less waste in scrap, and are
producible in more complex shapes. Die castings can be made in many
shapes not producible in stamped form.
Screw Machine Parts
Compared with screw machine products, die castings are produced more
rapidly, involve much less waste in scrap, can be made into shapes that are difficult or impossible to produce from bar or tubular stock, and may require fewer operations.
Sand castings
Compared with sand castings, die castings require much less
machining, can be made with thinner walls, can have all or nearly all holes cored to size, can be held within much closer dimensional limits, and are produced more rapidly in dies which make thousands of die castings without replacement. Die castings do not require new cores for each casting, are easily provided with inserts die cast in place, have smoother surfaces and involve much less labor cost per casting.
Permanent mold castings
Compared with permanent mold castings, die castings can be made to
closer dimensional limits and with thinner sections and holes can be
cored to near net shape. Die castings are produced at higher rates with
less manual labor, have smoother surfaces, and usually cost less per die casting.
