The Difference Between Casting & Forging. Casting is the process where metal is heated until molten. While in the molten or liquid state it is poured into a mold.

Posted September 30, Forging is stronger for a number of reasons, not least due to the internal stresses of the forged material bolsterring the crystaline structure and running along the shape of the forged item - effectively work hardening. Cast items are generally more brittle due to high carbon steel being used predominantly to aid the liquid metal flow and also the precipitation of the Carbon along the crystal walls in the material structure. I cannot remember the correct nomenclature off hand I recall "martensitic is in there somewhere , so, with regret, that's the best i can do on this at the moment!!! Posted December 22,

Both casting and forging are metal-working processes commonly used in industry. They are often not restricted to metals. The two processes differ in their principal operation. During the process of casting , the metal is heated until it melts and then the molten liquid is poured into a mould to obtain the desired shape. In the case of forging , the metal is being treated while it is in its solid state using the compressive forces until the desired shape is obtained. This is the main difference between casting and forging.

Metal forging and casting can at times be substituted for each other functionally to create a similarly effective product. Because of this, the two processes are easily confused, and each is best suited for a different application. That being said, the properties of each process can be vastly different. So, what are the differences?

A quick search reveals any number of metallurgical firms that can create said part for you, but their methods of doing so vary. Which method, then, is more suited to create the part you need at the quality you desire? The core of casting is in heating the component metal to a molten state and pouring it into a prepared mold. Though the mold is most often a die, sand and investment casting are often used for specific alloys or for parts with unusual dimensions and design. Once the metal cools into the basic desired shape, the metalworker then finishes the part with the details requested by the client either by hand or through further machining. Though the heating of the component metal is also essential to forging , heating for this method never gets so intense as to make said metal melt.

Forging vs. Casting: Which is better?

There are several different methods and techniques that can be used in manufacturing a variety of different metal components. Based on the purpose and ultimate use of the metal part, different procedures are used to create the highest quality piece possible.

Casting is the process where metal is heated until molten. While in the molten or liquid state it is poured into a mold or vessel to create a desired shape. Forging is the application of thermal and mechanical energy to steel billets or ingots to cause the material to change shape while in a solid state. We use castings for a wide range of wearparts and components that are too large, complicated, intricate or otherwise unsuitable for the forging process. We can forge parts up to 50kgs but the sheer energy required to forge larger items make casting a much more viable alternative. We currently cast mining and earthmoving components to kg.
