Precision casting is the use of carbon steel dihydrogen phosphate aluminium high precision casting and other production processes of casting products, its appearance and function are better, belong to the near type of products, is the preferred products in many fields. Precision castings and the traditional processing process of casting is also very different, from the production process and the application of the actual effect of the field can be reflected out.

Precision castings are casting metal material liquid poured into a certain mould shell, according to the cold violence after the establishment of the casting parts. There are many casting processing processes for precision castings, including metal material type casting, working pressure casting, fusion mould casting, disappearing mould casting and V method casting these. High precision casting parts are more highly precise in specification, and can be manufactured without further machining in the middle and later stages, or only a small amount of production solution is required. At the same time high precision casting can look complicated, thin and thin casting parts of the casting, not only can carry out small and medium-sized castings, large and medium-sized castings can also be very easy to cast.

Traditional casting and precision casting compared to become very unsmooth, traditional casting is in the condition of high voltage for the higher speed of the metal material liquid quickly replenished to the casting digital model, under the role of working pressure, so that it condensed, the back must also be deep processing solution before delivery, and in the whole process of casting suffered from raw materials, ambient temperature and its working pressure function in the condensation of forming The process often produces a bending condition. Therefore traditional castings are usually suitable for mechanical equipment geometry standard tolerances, etc. and application performance testing programmes are not too high areas.

From the development trend of today's industry, it seems that the level of refinement of product management is getting higher and higher, and the level of refinement of various components is also increasing, so for the production and manufacture of precision castings or have greater market prospects.
