Metal materials can improve their organizational structure and physical properties after forging. After the casting mechanism is hot-worked and deformed by forging, due to the deformation and plastic deformation of the alloy, the original thick cementite and columnar crystals become an equiaxed plastic deformation mechanism with fine crystals and uniform size, so that the original steel castings can be deformed. The compaction and welding of shrinkage porosity, looseness, air vents, and welding bumps, etc., the mechanism is getting closer and closer, which improves the plasticity and physical properties of metal materials.
What are the characteristics of CNC precision parts compared with castings?
The physical properties of castings are lower than those of steel castings of the same material. In addition, the forging process can ensure the continuity of the metal fiber structure, so that the connective tissue of the steel casting is consistent with the appearance design of the steel casting, and the metal material is streamlined and detailed, which can ensure that the parts have good physical properties and long life. The service life is made of steel castings manufactured by precision free forging, hot forging, warm extrusion and other processing techniques, all of which are unmatched by castings
A steel casting is an item in which a metal material is pressed to create a specified shape or suitable compressive force according to plastic deformation. This type of energy is typically accomplished with the application of a hammer or working pressure. The entire casting process creates a fine particle structure and improves the physical properties of the metal material. In the actual application of the component, an accurate design can make the particle flow in the direction of the main pressure. Castings are formed objects of metal materials obtained by various casting methods, that is, the refined shape memory alloys are introduced into the prepared casting molds by pouring, injection, suction or other casting methods, and after cooling. Items with certain appearance, specifications and characteristics obtained after falling sand, cleaning and post-treatment processes, etc.
