Metal hot processing technology

Casting is a kind of metal hot processing technology which has been mastered earlier by human beings. It has a history of about 6000 years. China has entered the full bloom period of bronze casting about 1700 to 1000 B.C., which has reached a high level in technology.

Casting is a method of casting a liquid metal into a casting cavity adapted to the shape of a part to be cooled and solidified to obtain a part or a blank. The casting material is mostly solid metal, but heated to liquid metal (example: copper, iron, aluminum, tin, lead, etc.), while the material of casting mold can be sand, metal and even ceramics.

Because of the different requirements of hot processing, the methods used will be different.
