Aluminium Castings, processing ways mainly include Sand Castings, Low Pressure Castings, and die castings / High Pressure Castings. 

Examples of items mainly are aluminium housing, pump gear box, pump housing, valve body, marine parts, Auto Parts , and turbocharger compressor wheel, bearing housing and compressor housing etc.. 

Die casting is the most important processing way for aluminium castings. 

Advantages of die casting:

• Excellent dimensional accuracy (depend on casting material, but typically 0.1 mm for the first 2.5 cm and 0.02 mm for each additional centimeter.
• Smooth cast surfaces.
• Thinner walls can be cast as compared to sand and permanent mold casting.
• Inserts can be cast-in.
• Reduces or eliminates secondary machining operations.
• Rapid production rates.
• Casting tensile strength as high as 415 megapascals (60 ksi).
• Casting of low fluidity metals.
•
