Compared with castings, the metal structure and mechanical properties can be improved after forging. Sichuan Hongyi Intelligent Machinery Co., Ltd. said that the original coarse dendrites and columnar grains become equiaxed with finer grains and uniform size due to the deformation and recrystallization of the metal after the casting structure is deformed by the forging method. The crystalline structure makes the original segregation, porosity, pores, slag inclusions, etc. in the ingot compacted and welded, and the structure becomes more compact, which improves the plasticity and mechanical properties of the metal. The mechanical properties of castings are lower than those of China BMW control arm forgings of the same material.

In addition, the forging process can ensure the continuity of the metal fiber structure, so that the fiber structure of the forging is consistent with the shape of the forging, and the metal streamline is complete, which can ensure the parts have good mechanical properties and long service life. Precision die forging and cold extrusion are used. Forgings produced by processes such as , warm extrusion, etc. are all incomparable to castings. Forgings are metal pressed, Sichuan Hongyi Intelligent Machinery Co., Ltd. indicates that the required shape or suitable compressive force is shaped by plastic deformation. This force is typically achieved through the use of a hammer or pressure.

The casting process builds a refined grain structure and improves the physical properties of the metal. In real-world use of the component, a proper design enables particle flow in the direction of the main pressure. Aluminum alloy forging called casting is a metal forming object obtained by various casting methods, that is, the smelted liquid metal is injected into the prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is cooled by falling sand. , cleaning and post-processing, etc., the resulting objects have a certain shape, size and performance.
