Casting has a long history,In acient times,casting was used for the coin,weapon or tools.And in modern times,casting is used for the machinery parts or precision castings.Castings play an very important role in the machinery products,such as motor casting,machine tool castings,iron casting tractor parts,mining machinery castings and so on.

Casting can also be divided into gravity casting and pressure casting liquid metal casting process.Gravity casting is the process refers to the liquid metal in the earth under the action of gravity,into the mold, also known as casting.The generalized gravity casting including sand casting,metal casting,investment casting,clay mold casting; narrow sense of the gravity casting metal casting refers specifically.Pressure casting is the process of the liquid metal into the mold under other external forces (excluding gravity).The generalized pressure casting including pressure die casting machine casting and vacuum casting,low pressure casting,centrifugal casting;the narrow defined pressure casting refers specifically to the metal pressure die casting machine casting,referred to as die casting.The plant precision castings have long been engaged in sand gravity casting and metal type. Several casting process is the most common non-ferrous metal casting,is the relative price of the lowest.

Metal casting is the production of heat-resistant alloy steel casting hollow cast mold of modern technology. Metal type using either gravity casting,pressure die casting can also be used.Metal mold mold can be used repeatedly,each pouring a liquid metal,obtained castings,very long life,and high production efficiency. Metal castings is not only dimensional accuracy is good,smooth surface,and in the case of pouring the solution of the same metal,the casting strength higher than the sand of more not easily damaged.Thus,in the mass production of non-ferrous metals,castings,as long as the the casting material‘s melting point,however, is generally preferred metal casting.Metal casting, however,there are some shortcomings:heat-resistant alloy steel and made it a hollow cavity machining are more expensive,so the costs of metal-mold and die casting mold costs,but overall it is cheaper than the more.Allocated to the cost of each product on the mold is obviously too high for small batch production, generally is not easy to accept.Metal-mold mold material size and cavity machining equipment,casting equipment capacity constraints,particularly large castings powerless.Therefore rarely used in small quantities and large production of metal casting.In addition,the metal mold, although the use of heat-resistant alloy,but the heat capacity is still limited, generally used for aluminum,zinc alloy,magnesium alloy casting,copper alloy casting has been rarely used, while for black metal casting even less.
