Difference Between Forging and Casting?

Question

I know casting is pouring molten metal into a cast and allowing it to cool. From what I gather most forged parts are made from ingots that are heated close to melting and then formed with presses and similar tools. The ingots are made from motlen metal are they not? What process do they use to make the ingots, and what makes the metal so different from a casting?

Answer 1

Pounding on the hot metal (not near melting) rearranges the grain structure making the piece stronger. Casting basically produces an even grain structure thoughout which tends to be brittle, while a forged piece is tougher (less likely to break.)

Answer 2

forged irons as greater high priced because of the greater huge production technique needed to fabricate them. all the club heads are formed from an uncut steel billet and pounded into the fantastic shape. This technique yields clubhead with lots softer sense and greater advantageous toughness interior the long-term (forged golf equipment as much less companies to cracking). And with forged hollow area backs there's a competent volume of forgiveness interior the hot lines popping out. i'm going to project that forged golf equipment are 'greater advantageous', with the advancements in casting technologies (Ping is a grasp at this) an excellent sort of a similar reward of a forged club could be had at a chit. sense isn't fairly a similar, even with the shown fact that it incredibly is getting very close.

Answer 3

Forged materials may not necessarily be cast ingots. Forging materials may come from shafts which are themselves forged by machine. Forging may be done manually such as those done by blacksmiths. Casting is pouring of molten metal into sand molds and allowing metal to cool down.

Answer 4

My collegues are mostly right. forging does improve toughness, by aligning the internal structure. But it does much more.



During casting, many defects including large voids and irregularities are formed. Forging (including drop forging) squeezes the "heat" and shrinking the voids and eliminating many deformities. These deformities are the source of future creep, fracture and points of internal stress. Forging can elmininate neary 95% of them if done properly.



sometimes there are two sets of forgings, with a heat soaking in between. These ingots are particularly expensive and are used in only highly engineered equipment
