Casting - advantages and disadvantages and product classification

Analysis of the advantages and disadvantages of casting:

Advantage：

1, can produce complex shape parts, in particular, the inner cavity of the complex;

2, adaptability is wide, the industry commonly used metal materials can be cast, a few grams to several hundred tons;

3, wide source of raw materials, low price, such as scrap steel, scrap, scrap etc.;

4, the shape and size of the casting is very close to the parts, reducing the amount of cutting, which belongs to the non cutting processing;

5, the application of a wide range of agricultural machinery in the 70%~80%, the weight of the machine tool 40%~70% are castings.

Disadvantages:

1, the mechanical properties are not as good as forging, such as coarse tissue, defects and so on;

2, sand casting, single piece and small batch production, high labor intensity of workers;

3, the casting quality is not stable, the working procedure is many, the influence factor is complex, easy to produce many defects.
