looks like cast, not forged, to me
Absolutely not, they are definitely drop forged ingots 👍looks like cast, not forged, to me
Yeah, for a long time the Imbel of Brazil forgings were the source.They used to come from Imbel in Brazil, which is supposedly one of the best forgers of steel firearm parts on the planet. I don't know where they get them now.
Such a cool picture 👍😎👍Here's a picture from inside the Colt factory in 1942:

awesome video! its cool too see how it goes downHere's a link to a 1911 frame being forged by the S&W factory. Notice how the end result raw forging is very similar to the one in my photo shared above 👍
Here's a screenshot of a S&W raw forged frame...

And here is a raw 1911 frame investment casting... As one can see, a lot of the work is already done, it will need a lot less machining then a raw forged frame would require.

Btw, I have no idea the manufacturer of this frame casting, I just put it up here as an example 👍
When Springfield Armory was using Imbel as their source partner, they used Imbel's forged frames and slides. Some of these were partially machined in Brazil and sent to SA for final in house machining. Some forgings were sent to SA for complete SA final machining, (usually SA higher end models). Some of the forgings were completely machined and all assembly fully done in Brazil, (usually the more basic models)., Springfield did use some cast frames from Brazil, I don't know if or when they stopped.
No different than Ruger's Pine Tree investment casting division making the casted components for many other gun firms, (receivers/frames, are a part of that). Yup, business is business, they will gladly sell their services to other firms, even their competition. Ruger still maintains a very good reputation for making good investment castings.I remember an old gunzine piece showing the S&W drop forge... and a crate marked "Kimber." All these outfits are in cahoots.
I understand your conclusion. It does look like there is a mold parting line but forging does the same thing. Investment casting (lost wax process) gives them a lot more opportunity to get closer to net finished form. According to casting house customer that I did some repair, upgrades and revisions on their molds for told me that they can move porosity around but can never completely eliminate it. The porosity and resulting grain structure are why castings are generally considered less desirable. Forging produces almost zero porosity and a more compact grain structure.looks like cast, not forged, to me
I wonder how they get the rotary forge past the link lug.They also have forged barrels, but the method used for the barrel making is called cold hammer forging,
They claimed some time back to having switched to a US source for their frame and slide forgings.Well Jimmy , I ain't your partner and I never said that the cast frames came from Imbel, I said from Brazil.Did you not know they used cast frames from S. America at one time?
