The configuration of the aluminum extruder is determined by the master cylinder, which is divided into forging and casting. What is the process like? Many customers do not understand why the price of our aluminum profile extruder has anything to do with the casting or forging of the master cylinder. In fact, this is related. Let's take a look at the process of forging and casting the master cylinder:
Extruder main cylinder forging: It is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, shapes and sizes. Forging and stamping are both plastic working properties, collectively called forging. Forging is a commonly used forming method in mechanical manufacturing. By forging, the as-cast looseness and welding holes of the metal can be eliminated. The mechanical properties of the forging are generally better than those of the same material. For the important parts with high load and severe working conditions in the machinery, in addition to the simpler shapes that can be rolled plates, profiles or welded parts, forgings are mostly used.
Aluminum alloy extruder main cylinder casting: It is a metal liquid forming process, that is, the molten liquid alloy is injected into a pre-prepared mold to cool and solidify to form a casting. Casting can be subdivided into sand casting and pressure according to the process method. Casting, investment casting, shell casting, lost foam casting, low pressure casting, gravity casting, etc.
