What is the difference between forging and casting?

In the mechanical industry, manufacturing of various component requires standard procedure whether it’s casting, forging, molding or forming. Many people asking this question many times that what’s the difference between forging and casting. Let’s take a quick look about forging and casting.

Both manufacturing processes are very different, in forging components are created by heating it in a fire or furnace. While in casting pouring molten metal inserted into mold and gets desired shape.

So based on the procedure you can easily differentiate both method, in forging parts are frequently heated during forming while in casting metals are completely liquefied before it gets desired shape.

Based on the manufacturing process Forging is far better than Casting, because in casting process metal completely liquefied and after cools back it decrease the overall strength. Which may negative factor when higher and superior quality parts needed. But based on the requirement it’s tough to choose which process is better, forging provides higher tensile plus fatigue strength while casting provides precise dimension plus critical shape creation.

While considering budget in manufacturing for small volume casting procedure is cheaper and for larger production forgings can be cheaper, sometime it may vary in final output product. For some complex part casting can easily provide more reliability and accuracy compare to forging.

Last words, this comparison is totally depending on the requirements, what’s the design and dimension of parts, how much strength applied while in used, reliability and corrosion resistance feature keeps in mind or its less in priority.

Waiting for your ideas and view regarding both processes.
