Forged parts are parts produced by metal forging in a red-hot state by means of air hammers or presses. Cast parts are metalized into a liquid state, poured into a cavity with a specific shape, and cooled and solidified. So what is the difference between forging and casting?

Distinguish forgings and castings in principle: forgings are parts that are produced by forging of metal in a red-hot state by means of an air hammer or a press. Castings are parts produced by metallizing into a liquid state, pouring into a cavity with a specific shape, and cooling and solidifying. To put it bluntly, forging parts are to soften and shape the metal, while casting parts are to turn the metal into a thin soup and then cool it to solidify.

Distinguish forgings and castings in terms of performance: forgings are dense and have good mechanical properties. The processing of forging parts can ensure the continuity of the metal fiber structure, so that the fiber structure of the forging parts is consistent with the shape of the forging parts, and the metal streamline is complete, which can ensure that the parts have good mechanical properties and long service life. The mechanical properties of castings are not as good as those of forgings because there may be defects such as sand holes, pores and shrinkage holes. However, because the castings are converted into molten iron, the flow properties are good, and complex shapes can be formed.

Distinguish forgings and castings from the materials used: the processing materials for forgings are mainly carbon steel and alloy steel of various compositions, followed by aluminum, magnesium, titanium, copper, etc. and their alloys. The original state of the material is bar, ingot, metal powder and liquid metal. Most of the materials required for casting processing are metal, wood, fuel, and modeling materials.

In contrast, the processing of forging parts rarely produces dust, harmful gases and noise, and has a more obvious effect on environmental protection. In terms of performance, forgings have dense structure and good mechanical properties. The mechanical properties of castings are not as good as those of forgings because there may be defects such as sand holes, pores and shrinkage holes. However, castings can be formed into complex shapes because they are melted into molten iron and have good flow properties.
