Casting is a manufacturing method with a long history

Casting is a manufacturing process in which molten metal liquid is poured into a mold, and then condensed to obtain a part with the desired shape and function. Casting is a common manufacturing method.
The advantages are: low manufacturing cost, great coordination of processing technology, can obtain chaotic shapes and large and medium-sized castings, occupying a large proportion in the manufacture of machinery and equipment, such as CNC lathes accounting for 60-80%, and cars accounting for 25%. Tractors account for 50-60%.
Following the progress of industrial production expertise, the quality of large-scale castings immediately jeopardizes the quality of commodities. Therefore, casting occupies a key direction in the machinery manufacturing industry. The casting professional skills are also very dexterous, very in the late 19th century and the first half of the 20th century, showing many new casting methods, such as low-pressure casting, porcelain casting, continuous casting, etc., which were sound and effective at the end of the 20th century. change.


Because of the current development of regulations on casting quality, casting precision, casting cost and casting automation, casting professional skills are moving towards refined management, import substitution, high-quality, automation and clean-up. For example, in the past few years in China Fine casting professional skills, continuous casting professional skills, special casting professional skills, casting automation and casting composition imitating professional skills and other levels are dexterous.
The main casting process includes: metal smelting, model production, pouring and coagulation, and mold-out carding. The main materials used in casting are cast steel, cast iron, cast non-ferrous aluminum alloys (copper, aluminum, zinc, lead, etc.).
The casting process can be divided into gravity casting, working pressure casting and sand casting.
The most common casting method is sand casting, followed by special casting methods, such as metal casting, investment casting, plaster casting, etc. Sand casting can be divided into clay sand casting, organic adhesive sand casting, epoxy resin self-setting sand casting, and lost foam casting.
Gravity casting refers to the process of introducing molten metal into the mold under the actual effect of the earth's gravity, also called casting. Theoretical gravity casting includes sand casting, metal casting, investment casting, mud casting, etc.; the narrow meaning of gravity casting specifically refers to metal casting.
Working pressure casting refers to the process of introducing molten metal into the mold under the actual effect of other external forces (no force). The theoretical working pressure casting includes the working pressure casting of die casting machine, low pressure casting, centrifugal casting, etc.; narrow working pressure casting refers specifically to the metal working pressure casting of die casting machine, commonly known as aluminum die casting. These types of casting processes are the most common and the least expensive in non-ferrous metal casting today.
Sand casting is a traditional casting process that uses sand as the main modeling design material to produce molds.
