Talk about an important content of precision casting
Posted by Admin
Precision casting includes modeling (using molding sand to form the cavity of the casting), core making (forming the internal shape of the casting), and mold matching (putting the core into the cavity and closing the upper and lower flasks together). Modeling is a key link in casting. The qualified molten metal is poured into the sand box equipped with the mold. The pouring stage is very dangerous, so special attention should be paid to it.
This led to a wider and more intense debate. We believe that the adjustment of the old majors must be guided by "adjustment, reform, rectification and improvement", based on the needs of my country's national economic construction, scientific and technological development and the specific conditions of the school. Pig iron is mainly made of iron ore through blast furnace smelting. The product. Cast iron is made by re-melting cast iron in a furnace and processing it into cast iron.
Therefore, the raw materials and processes of the two are different, and cast iron is a secondary processed product of pig iron. The development direction of automated production lines is an inevitable choice for the development of my country's manufacturing industry, and it is also the realization of the scientific development of social economy and the smooth completion of the new industrialization road. Compared with the traditional production line, the Bolis machining automation production line has good manufacturing flexibility, high production precision and significantly improved product productivity.
Automatic spraying production line, automatic welding production line, automatic electroplating production line, etc. The typical ones are the following two: one is an automatic machining production line, which is used in the mechanical parts processing industry; the other is an automatic assembly production line, which is used for the post-assembly production of various products. Its main classification is based on customer industries.
The important basic equipment of the electromechanical industry is a means of modernizing the production of pillar industries such as automobiles, motorcycles, aerospace, molds, machine tools, and electronics. CNC machine tools are also an important part of the third industrial revolution in the world. It has many features such as automation and easy realization of process compounding and information integration. It is especially suitable for processing complex shapes and parts, small and medium batches, and flexible production of various varieties. Therefore, it has become an important basic equipment for modern advanced manufacturing technology and a color flow product in the world machine tool market.
