What is the relationship between precision casting processing and casting?
Casting is the process of casting liquid metal into a casting cavity, cooling and solidification to obtain the finished product. In terms of type, there are sand casting and special casting. Precision casting belongs to special casting, and the finished product generally does not require further processing. Therefore, the relationship between casting and precision casting is a subordinate relationship.
2. What are the applications and products of precision casting?
The application of precision casting can be said to be very extensive. Specifically, in industries such as petrochemicals, electronics, energy, light industry, textiles, pharmaceuticals, medical devices, and transportation. Its specific products include various castings such as copper castings, aluminum castings, steel castings, copper aluminum castings, etc.

3. Which technical field does precision casting belong to?
Precision casting is a type of casting, so it naturally belongs to the field of casting. Casting usually belongs to the field of metallurgy or material forming, as it is an independent industry without industry planning.
Technical requirements and material selection for precision casting
In the production process, precision casting directly pours solidified substances such as liquid at room temperature into its specific shape of the mold. Precision casting is mostly solid metal, which is then directly heated into liquid metal. The metal materials used include lead, copper, iron, aluminum, etc.
The mold material in precision casting can be metal, sand, or ceramic. During the use process, different methods need to be used according to different requirements. This production method is called casting, and its metal mold can be gray iron or ductile iron.
Precision casting can produce complex parts, especially complex inner cavity blanks, during the machining process, and is widely used. Generally speaking, metal materials commonly used in industry can be cast.
The source of raw materials for precision casting is very extensive, and the price of products during use is very low. The shape and size of equipment waste, scrap steel, and debris castings are very close to the parts, which can effectively reduce their cutting amount and belong to the category of less cutting processing.
The mass production of precision casting has effectively created favorable conditions for factories. During the use process, very advanced technical modeling methods were adopted. The air impact molding line of the product can meet the requirements of fast and high-precision molding production lines, and efficient core methods such as shell core can be selected for core methods.
