Casting is a more economic development of the forming method of the hairy embryo. It can show the rationality of the information for the complicated parts. For example, the engine block cylinder head of the engine, the propeller of the ship the aircraft their exquisite handicrafts, etc. Some parts that can't be drilled, such as nickel base superalloy parts of gas turbine generator, can't be formed without casting.

Heat treatment is of great significance to foundry engineers mechanical structure design engineers. It is a very valuable way to improve the quality of raw materials. By means of heat treatment, the structure characteristics of pig iron can be changed damaged. In addition, higher compressive strength strength can be obtained, the resistance of friction coefficient can be improved Some.

Because of different purposes, there are many types of heat treatment, the basic key can be divided into two categories. The first category is that the organizational structure of Zhejiang low-pressure aluminum casting factory is easy to change should change after heat treatment, the second is that the basic organizational structure changes. The first heat treatment procedure is applicable to remove the internal stress caused by different cooling conditions standards during the whole casting process. The structure, compressive strength other mechanical equipment characteristics will change significantly due to heat treatment.
