What Is Customized Hot Forging  Parts? 


According to the forging temperature, forging can be classified into hot forging, cold forging and warm forging. Most mental components intended to be forged are performed under hot forging.

Brass hot forging can be defined as “ a shaping process in which a brass bar, is worked to a predetermined shape by one or more processes such as hammering, upsetting, pressing and so forth where the bar is heated up to about 75% of its melting temperature”. The process begins with a cast ingot, which is heated to its plastic deformation temperature, then forged between dies to the desired shapes and size.







 Customized Hot Forging  Parts The Advantages & Benefits of Brass Hot Forging


The brass hot forgings are quality parts, comparing favorably in material integrity, dimensional tolerance and surface finishing with products made using other major metalworking processes. As a result of deformation, hot brass forging grants superior density and freedom from flaws. Forming under heat and pressure in precise closed dies produces dimensional accuracy, always repeatable part to part and lot to lot. 







The specific advantages of brass hot forging parts are as follows:


1. Higher Strength


As the forging temperature of the brass bar is prior to the melting temperature, the flow stress and energy required to form the material are decreased and the strain rate or production rate can also be increased. Therefore, hot forging results in metal that is stronger than cast or machined metal parts.


2. Lower Overall Cost


Mass production of brass forged parts lends itself to maximum savings. However, smaller quantities of copper alloy forgings can also prove economical when specific design problems must be overcome. These problems include leak integrity, close tolerances, high strength with low weight, and non-symmetrical shape. Besides, hot forging don’t have to reach the molten temperatures.


3. Leak Resistance


The dense non-porous forged metal permits the designer to specify thinner sections without the risk of leaks due to flaws and voids. Often the thinner forged parts result in lighter weight and lower part cost compared to other forming processes.


4. Close Tolerances


Overall part dimensions are held closer than in sand casting. Dimensions show minimum variation from part to part and permit automatic chucking and handling in subsequent operations. The precise designs on the die surface can produce sharp impressions on the forging surface, which is not economical with other forming processes.

The cold forging manufacturing process is performed at room temperature. While the hot forging manufacturing process is performed at extreme high temperature (up to 1150°C for steel, 360 to 520°C for al-alloys, 700 to 800°C for cu-alloys).

The cold forging manufacturing process increases the strength of a metal through strain hardening at a room temperature. On the contrary the hot forging manufacturing process keeps materials from strain hardening at high temperature, which results in optimum yield strength, low hardness and high ductility.
