Squeeze casting, also known as liquid metal forging, is a combination of casting and forging process.
The molten metal is poured into the bottom half of the pre-heated die. As the metal starts solidifying, the upper half closes the die and applies pressure during the solidification process. The amount of pressure thus applied is significantly less than used in forging, and parts of great detail can be produced. Coring can be used with this process to form holes and recesses. The porosity is low and the mechanical properties are improved.
Both ferrous and non-ferrous materials can be produced using this method.
