Sand cutting adaptability is very wide, small pieces, large pieces, simple pieces, complex pieces, single pieces, large quantities can be used. Sand mold is more refractory than metal mold, so materials with higher melting points such as copper alloys and ferrous metals are also used in this process.

Metal cutting types modeling methods are customarily divided:
① ordinary sand type cutting, including wet sand type, dry sand type and chemical hardening sand type 3.
② Special cutting, according to the molding material can be divided into natural mineral sand as the main molding material of special cutting (such as investment cutting, mud cutting, cutting workshop shell cutting, negative pressure cutting, solid cutting, ceramic cutting, etc.) and metal as the main casting material of special cutting (such as metal cutting, pressure cutting, continuous cutting, low pressure cutting, centrifugal cutting, etc.).

In ancient times, China, India, Babylon, Egypt, Greece and Rome had cut weapons, sacrificial objects, works of art and household utensils. Early castings were made of gold, silver, copper and their alloys. The Bronze Age is a glorious page in the history of human civilization; later cast iron pieces appeared. Iron castings were widely used in China as early as the Warring States period, and the technical tradition has a long history. Metallurgy and cutting are complementary processes, and the term "metallurgy" in ancient China reflects this fact. Although the cutting process has developed into a relatively independent branch of the mechanical manufacturing process, it is still inseparable from the metallurgical process.
Metal cutting is to cut metal into shapes that meet certain requirements.

Metal cutting is to cut metal into shapes that meet certain requirements. Cutting blanks because of nearly forming, and to achieve the purpose of no machining or a small amount of processing to reduce the cost and reduce the time to a certain extent, cutting is one of the basic processes of modern machinery manufacturing industry.
