Process of casting
Casting is a metalworking technique in which molten metal is poured into a mold and then allowing it to cool and solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. The metal piece can be finished with grinding, sanding and polishing. This is one of the oldest metalworking techniques in the world.
According with the worldwide census of casting production, the top nation in this production is China with millions of tons produced in their foundries and exported to the rest of the world.
There is a huge range of parts made by casting such as joints, nuts, pipes, valves, fittings… and they are used in many different sectors as automobile, aerospace, railways, shipping, construction, farming, mining, machinery, defence, plant machinery, electrical, household…
