Also, Casting aluminium parts relies on a widely accessible material with which casters are most familiar and used to working. In comparison, die casting and gravity pouring need various other pieces of kit that are costly for both the purchasing and upkeep. Also, the design of Die casting must of necessity be simpler, which costs the die design period and time. However this kind of thinking is standard worldwide because large sets are costly and in a highly efficient production process produce up to 100,000 parts or more equivalent to taking long months to just make dozens of single piece parts required earlier for much lower quantities. In addition, aluminium castings are highly rust-resistant, offering long life even in the most punishing industrial environments. Moreover, the casting process permits intricate designs to be made with high precision. This means less post treatment processing-simplified manufacturing, reduced costs and shorter lead-times. Finally, whole sections (such as the intake manifods for internal-combustion engines) that are now made of aluminium could be made of cast iron or iron-based materials and should be returned for remelting if they have out-lived their usage lives.
