Rough cast is a type of casting that has not been processed or has a small amount of processing. Rough castings retain the material characteristics of the raw materials and are typically used for mass production. Rough castings can also use advanced technologies such as 3D printing to improve production speed and shorten production time. During the production process, the rough castings will undergo secondary treatment. The rough castings have high stiffness and can withstand significant pressure. After secondary treatment, rough castings will have good corrosion resistance and can adapt to more environmental conditions.

When making rough castings, casting alloys and other materials are usually used, which have strong load-bearing capacity and can withstand greater pressure and pressure. During the mass production of rough castings, the cost of individual parts is reduced and waste is reduced. Through advanced casting technology and strict quality control, rough castings reduce the manpower and material resources required for subsequent production. Rough castings can also flexibly produce various accessories that meet different needs by changing the gate and manufacturing process. Rough castings are widely used as an important basic material in the fields of petrochemicals and construction.
