Forged aluminum ring
When purchasing hubs and spindles, product integrity is critical often making or breaking a part in the field. Machined castings or hot-rolled machined bars tend to have poor structural integrity or inclusions that lead to problems with cracking and part failure. Forging has proven to be a successful solution to these problems.

Production of Aiboer Technology 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 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 forgings
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.
Production process of aluminum forgings
The forging process can produce parts that are stronger than any other metalworking process. This is why forgings are almost always used on components that are critical to reliability and personal safety.
But you rarely see forgings, because they are usually parts included in the assembly items, such as aircraft, cars, tractors, ships, oil drilling equipment, engines, missiles and various equipment.
Because of the special requirements for hardness and strength of aluminum forgings, there are strict requirements for production process. Aiboer strictly controls each production process of aluminum forgings, strives to do the best in mold manufacturing, forging processing, finished product inspection, packaging and transportation, and provides customers with high-quality aluminum forgings.
Mold design and production
Die manufacturing is the first step for customized aluminum forgings. Once a new order is placed, our engineers will design the die according to the customer's aluminum forging drawings.
Aluminum billet cutting and heating
Our warehouse stores aluminum for forging production. After the die is completed, the aluminum billet will be taken out of the warehouse, cut into the required length, and heated for pretreatment before forging.
Closed die forging
Put the heated aluminum billet under the upper and lower molds, and then press it into the desired shape.
Heat treatment
In order to improve the strength and mechanical properties, heat treatment shall be carried out after forging. Like castings, common heat treatment methods for forgings include normalizing, quenching, annealing, tempering, solution treatment, etc. Heat treatment is only carried out when necessary.
Shot blasting
In order to remove oxide scale and obtain better surface quality, the forgings will be shot blasted. After shot blasting, the product will look clearer and smoother.
Machining
Our main processing equipment is CNC lathe and CNC. CNC lathes are used for simple machining, while CNC is used for precision machining.
Surface treatment
If there is no special surface treatment requirements, water/oil antirust paint can be applied before packaging. Sometimes, special surface treatment is carried out according to the application needs of aluminum forgings, such as painting, galvanizing, electroplating, etc.
Inspect
Inspection is also an important step. We can divide the inspection process into external inspection and internal inspection. External inspection includes dimension inspection and appearance defect inspection. Internal inspection refers to internal performance inspection.
Packaging and delivery
In order to protect the product from damage, we pack the product in plastic bags, and then put it into standard wooden boxes. In addition, we can also customize the packaging according to customer requirements.
