The selection of linear dimensional tolerance grades for die castings is shown in Table 4-7 and Table 4-8. The tolerance band should be symmetrically distributed, i.e., one half of the tolerance is positive and the other half is negative. If asymmetric setting is used, it should be indicated on the drawing. For dimensions that are generally not machined, the hole takes a positive value and the shaft takes a negative value; for dimensions that are to be machined, the hole takes a negative value and the shaft takes a positive value.

Die-casting aluminum alloy has a wide range of uses, mainly used in automobiles, communication industry, engineering and construction, electric power, electronics, computers, household appliances, high-fidelity speakers, warships, aviation, aerospace and other military industries.

The manufacturing process of aluminum alloy in the automotive field mainly includes stamping, die casting and extrusion molding, while die casting is the main production method of aluminum alloy parts, and the dosage of aluminum alloy die casting in the automotive field reaches about 80%, while extruded parts and calendered parts account for about 10% each. Under the requirements of environmental protection and energy saving, automobile manufacturing is constantly moving towards light weight, which promotes the wide application of aluminum and magnesium alloy with low density and high strength in automobile parts.
