Forging vs Casting

Forging and casting already become the two main metal forming processes for all kinds of industries. Today, we would like to discuss the differences between forging and casting in below:

Forging is processing way that putting pressure on metal blank by forging machinery, making it produce plastic deformation, in order to obtain certain mechanical properties,a certain shape and size of forgings. Forging can eliminate the as-cast osteoporosis of the metal, welded holes,and generally mechanical properties of forging is better than that of the same material of the casting. So for those important components that require to undertake high mechanical load, or working in serious conditions, in addition to simple shape rolling plate,or welding parts are available, all will consider forging process.

According to its forming methods,forging can be divided into:

1)Open die forging: Use impact or pressure to make metal deformed on the up and down irons (anvil blocks) to obtain the required forgings, there are mainly two different kinds of working way, manual forging and mechanical forging.

2)Closed die forging: Metal blank is shaped by compression deformed in the bore of the forging dies,this process can be divided into die forging, cold heading, rotary forging, extrusion, etc.According to the deformation temperature, forging can be divided into hot forging (processing temperature above the recrystallization temperature of billet metal), warm forging (below the recrystallization temperature) and cold forging (room temperature). Forging materials are mainly carbon steel and alloy steel, followed by aluminum, magnesium, titanium, copper and its alloy etc. Normally the original state of material is a bar.

Casting is a metal forming process that melting the metal into certain requirements of the liquid and then pouring it into the mold, after cooling solidification, we can get desired shape and sizes. Production cost of blanks produced by casting is low. For complex shape, especially the parts with complex inner cavity, casting can show its economical efficiency more; At the same time, it has a wide adaptability,and has better comprehensive mechanical properties. But materials that needed in casting production and equipments (such as metallurgical furnace, sand mixing machine, molding machine, core making machine, shakeout machine, shot blasting machine, etc.) will produce dust,harmful gas and noise. Thus it will do harm to environmental.

Forging & Casting Experts in China



Forging and casting are the two most reliable and versatile methods for manufacturing metal parts and components for industrial, or heavy-duty applications. In many cases, the same part could be created using either process, with roughly equal results, however, the two cannot be interchanged without significant revisions to part designs. Pricing can vary greatly from project to project; neither process will consistently be the more affordable option.
