Brass forging is a process in which a brass forging press machine applies extremely high pressure to a single piece of brass or brass alloy that has been heated to about 1500 degrees Fahrenheit (815℃). The softened metal is then pressurized, beaten and shaped to produce seamless brass parts. The brass forging process can produce almost any type of brass with three-dimensional shape or form, ranging from a few ounces to several tons. Various types of brass forging include stamping or closed die forging, open die forging, cold forging and seamless rolling ring forging.
The brass forging process, which will not change the structure of metal, can actually make metal stronger than casting parts by about 15%. The extruded brass raw material will be made into a shape similar to the final forged components and then heated to get the final parts. The process of forging brass parts can reduce metal scrap and is faster than the process of machining parts. The forging process also produces a nonporous surface, which makes brass parts more attractive.
Round ring-shaped parts, which are formed by the open die forging process, are used to roll into ring-shaped forgings. This forging is realized via the pressure of two axial rollers (driving roller and idler roller), where the idler rollers rotate to apply pressure to the inside of the ring-shaped brass parts, and the driving roller applies pressure to the outer edge of the parts. The ring-shaped brass parts will be constantly straightened until the required diameter is reached.
