Precision Casting for Aluminum Parts Technical Characteristics of
Aluminum Casting Precision Casting
The production method of pouring liquid metal into a mold cavity
that is suitable for the shape and size of the part and waiting for
it to cool and solidify to obtain a blank or part is usually called
metal liquid forming or casting.
The processes of aluminum product casting include gravity casting,
high-pressure die casting, sand casting, and centrifugal casting.
Casting aluminum alloy has good casting properties and can be made
into parts with complex shapes; it does not require large
additional equipment; it has the advantages of saving metal,
reducing costs, and reducing working hours, and is widely used in
the aviation industry and civil industry.
Process characteristics of aluminum product casting
01. It can produce parts with any complex shape, especially parts
with complex inner cavity shapes.
02. It has strong adaptability, unlimited alloy types, and almost
unlimited casting size.
03. The source of materials is wide, scrap can be remelted, and the
equipment investment is low.
04. The scrap rate is high, the surface quality is low, and the
working conditions are poor.
Technical characteristics of aluminum casting
01. Suitable for making complex shapes, especially blanks with
complex inner cavities;
02. Wide adaptability and low cost;
03. For some materials with poor plasticity, such as cast iron,
sand casting is the only forming process for manufacturing its
parts or blanks.
