(1) The adaptability to the shape and size of the casting is strong. It can produce blanks of various shapes and sizes, and is particularly suitable for the manufacture of parts with complex internal cavities.
(2) Strong adaptability to materials. It can be adapted to the forming of most metal materials, and has unique advantages for casting materials that are not suitable for forging and welding.
(3) The cost of castings is low. This is because the source of the foundry raw material is rich, and the shape of the casting is close to the part, which can reduce the amount of cutting and reduce the casting cost.
Therefore, casting is one of the most important methods for the production of blanks, such as 60% to 80% by weight of the machine tool and 50% to 60% of the machine by casting. However, due to many casting process steps, a variety of casting defects are easily generated, and the general casting grains are coarse and the mechanical properties are not as good as forgings. Therefore, castings are generally not suitable for making important parts with complex forces and large forces, but mainly for parts that are not stressed or subjected to simple static loads (especially suitable for compressive stress), such as boxes, beds, brackets, Stand and so on.
