Aluminum alloy die casting technology has been developed for more than a hundred years, and with the evolution of various needs, it has become one of the most important roles in aerospace, automobile, motorcycle, and mechanical hardware, and so on. Aluminum alloy die casting is suitable for mass production and cost-effective manufacturing technology, but in the actual application of the balance of its advantages and disadvantages in order to achieve the best results, which is precisely the subtlety of the die casting technology. Some of the significant advantages and disadvantages of aluminum alloy die casting are briefly analyzed as follows:

PROs:

High precision and good surface quality: Aluminum alloy die-castings usually have extremely high dimensional accuracy, and their surfaces are smooth and flat, reducing the need for subsequent machining.
High production efficiency: Die casting is a rapid molding technology, suitable for mass production, which can significantly shorten the production cycle and reduce production costs.
Lightweight: Aluminum alloy is lightweight and has good mechanical properties, making it suitable for use in automotive, aerospace and electronic products where weight reduction is required to achieve energy savings.
Good Mechanical Properties: Aluminum alloy die casting has high strength and rigidity, suitable for structural parts.
CORROSION RESISTANCE: Aluminum alloy has a natural resistance to oxidation, which makes the die castings resistant to corrosion in most applications and prolongs their service life.

CONs:

High Initial Cost: Aluminum die casting molds are more expensive to produce and are suitable for mass production to spread the cost of the molds, while small batch production is not economical.
Complex structure limitation: Although die casting is suitable for manufacturing complex shapes of parts, too complex structure may lead to higher difficulties in mold design and production, and even increase the risk of high defects during mass production.
Material Waste: During the die casting process, a lot of sprues and overflow materials will be generated, which must be recycled and reprocessed, resulting in a certain amount of material waste.
Porosity problem: Air holes or voids may appear in the die casting, which may affect the mechanical performance and sealing, especially in high pressure applications.
Limited material selection: Die casting is only suitable for some specific alloys, such as ADC3, ADC6, ADC10, ADC12, etc. Not all aluminum alloys or other metals can be die cast.
