No matter what kinds of material castings, it the following major requirements:

Firstly, material requirements, main hardness, tensile strength, elongation, impact toughness.

Secondly, the dimensional accuracy and shape accuracy. Different castings have different requirements, using different sizes and geometric tolerance standards and different tolerance levels.

Thirdly, according to the requirements of use, the castings of other defects specified acceptance requirements. Such as stomatal, trachoma, shrinkage,slag, sand hole, cracks, etc.
