The most common casting

method

Manual work: 

flexible, easy to operate, 

but low efficiency, 

high labor intensity, 

low dimensional 

accuracy and surface 

quality

Manual molding:

large, complex castings of single, 

small batches and difficult to use moulding machines

Machinery: 

high dimensional 

accuracy and surface 

quality, but large 

investment

Mechanical molding: 

suitable for medium and small 

castings in batch production

Non-ferrous alloy castings

produced in small or large 

quantities are also used in the

production of iron and steel 

castings

Casting precision, 

high surface quality, 

compact structure, 

good mechanical 

properties, 

high productivity

Low

Non

metal

Small batch, preferably large and medium sized non - ferrous alloy castings, can produce 

thin - walled castings

With compact structure, high production rate, 

simple equipment, 

various casting types 

can be adopted, 

but the production 

efficiency is low

die 

casting

Aluminum magnesium alloy

Large - scale production of

 various non - ferrous alloy 

casting, thin - walled casting, 

pressure - resistant casting


High precision casting 

size, smooth surface, 

compact structure, high productivity and low cost

But die-casting machines and casting costs
