Compare High-pressure aluminum die casting with other Manufacturing Processes
Forgings
the die casting can produce more complex shape than forgings Process.And can produce some shapes that not forgeable.The die casting can be held to closer dimensions,have thinner sections,and have coring not feasible in forging
Extrusions
Compared to extrusions, die casting will be manufactured faster and much more net shape. Features and depressions on the tops and bottoms and sides, can be produced in a single operation. There's less waste using die casting than extrusion. Holes could be cast in place to save extra machining cost.
Plastic Injection moldings
Compared with plastic injection moldings, die casting is more stiffer,stronger, more heat resistant,more stable dimensionally. Support prevent electromagnetic emissions and radio frequency. For chrome plating, die castings are much better than plastics. Die castings have a great degree permanence under load than plastics.
Screw Machine
Compared with screw machine products, die castings are made more quickly, include fewer waste in scrap, can be produced into shapes which are impossible or difficult to make from tubular stock or bar , and may also need fewer operations.
Stampings
Compared with stampings, the die casting can often replace some parts. Die casting generally need fewer assembly operations, could have nearly any desired variation in section thickness,could be held within closer dimensional limits, involve less waste in scrap, and are producible in many complex shapes. Die castings can be produced in a lot of shapes not producible in stamped form.
Permanent mold castings
Compared with permanent mold castings, die castings can be produced to closer dimensional limits and with thinner sections .that holes could be cored to near net shape. Die castings are made at higher rates with fewer manual labor, have smoother surfaces, and generally are less expensive per die casting.
Sand castings
Compared with sand castings, die castings need fewer machining, can be produced with thinner walls, can offer all or almost all holes cored to size, could be held within much closer dimensional limits, and are produced more quickly in dies that produce thousands of die castings without replacement unit. Die castings don't require new cores for every casting, are easily supplied with inserts die cast in place, have smoother surfaces and involve fewer than labor cost per casting.
