Production of Chalco Aluminum forgings

Casting and forging

Forging is a manufacturing process in which metal is pressed, knocked or extruded into high-strength parts under great pressure. This process usually (but not always) performs hot working by preheating the metal to the desired temperature before processing. It is important to note that the forging process is completely different from the casting (or casting) process, because the metal used to make forged parts will never melt and pour.

Compare Casting Forging
Strength: Casting cannot obtain the strengthening effects of hot and cold working. Whether open or closed die forging is used, the forging process surpasses casting in predictable strength properties – producing superior strength that is assured, part to part.
Prevention of defects through pre-working: A casting has neither grain flow nor directional strength, and the casting process cannot prevent formation of certain metallurgical defects. Preworking forge stock produces a grain flow oriented in directions requiring maximum strength. Dendritic structures, alloy segregations and like imperfections are refined in forging.
Reliability of Production: Casting defects occur in a variety of forms through the production process, requiring tight process controls and inspections to ensure a reliable final product. Casting defects occur in a variety of forms through the production process, requiring tight process controls and inspections to ensure a reliable final product.
Response to heat treatment: Casting defects occur in a variety of forms through the production process, requiring tight process controls and inspections to ensure a reliable final product. Forgings respond more predictably to heat treatment and offer better dimensional stability.
Flexibility of production to demand: Some castings, such as special performance castings, require expensive materials and process controls, as well as longer lead times. Open die forging processes adapt to various production run lengths and enable shortened lead times.

Aluminum mold forgings and free forgings

Free forgings

Free forging is a processing method that uses impact force or pressure to make the metal deform freely in all directions between the upper and lower anvil surfaces without any restrictions to obtain the required shape, size and certain mechanical properties.

Free Forgings

Free forging uses simple the tools and equipment, with the features of versatile and low cost. Compared with casting, free forging eliminates shrinkage cavity, porosity, porosity and other defects, so that the blank has higher mechanical properties. Forgings are simple in shape, flexible in operation, and products are generally with the simple shapes such as shafts and rings are produced.

Free forging controls the shape and size of forgings by manual operation, so the forging has low precision, large machining allowance, high labor intensity and low productivity. Therefore, it is mainly used for single piece and small batch production.

Mold Forging is forging with molds, which are used to forge complex forgings with high precision requirements.

Free forging basically does not use molds, but can only forge extremely simple things such as shafts and rings. Mold forging can forge products with many structures, control the dimensional tolerance of products, and reduce the amount of turning.
