I love the straightforward explanations of the differences between the different mechanics of forged versus cast. Wish I would have found this 3 years ago. Knowledge is gold.
I'm here to say thank you. I've been finding the real reason about forging iron rather than casting. And this video explain it really well. Thank you again
I work for a hot forging + machining company called Metal Technology srl (brass copper and aluminum), and it is unbelievable how many customers come to us asking to switch from casting to hot forging, they have solved a lot of issues, also regarding porosity. Your explanation is 100% clear and on point!!! And sometimes it happens that hot forging is also cheaper than casting, if you have the right know how to design the item 💪🏻💪🏻
I've always been thinking about mold vs forge while taking showers ever since i learned about reforged swords in fantasy tabletop games somwhere around 1998. Today i decided to finally study it. Thank you for this informative video.
All the jet turbine parts are actually cast. They use a Hipping process to remove the voids from inside the casting. Also complex pieces cannot be forged, only simple structures.
casting can be improved with techniques like casting under vacuum (removes air bubbles), ultrasonic agitation (removes air bubbles, likely can be utilized to improve crystaline structure of the metal formation), and probably specialized heating / cooling schedules (will change the crystaline structure of the metals forming) forging is obviously a great method when the application calls for it and if the part can be practically forged. when it can't, casting is an OK alternative...as are other options such as extrusion.
all metals are extracted in cast form i.e. you melt suff and pour stuff ..... billet forming, forging etc are heat treatments to make the metal have different properties usually to make them stronger in some specific way
No... casting is referring to the process of pouring molten metal into a mold and letting it cool so it assumes the shape of the mold. Forging is shaping it using force. Forging can be done hot or cold, and metal can be forged without being melted beforehand.
Nice video...I've been shopping for a pistol - a 1911 .45 ACP to be specific...Some frames are cast - others are forged...From what little I know of solid metal handgun frames - the forged are said to be a better quality overall. And btw - I like your selection of bourbon on your shelf.
Taurus, Springfield, Colt all still forge their guns. Budget wise it goes in that order from least expensive to most expensive. Just check the description because some of the concealed carry models have aluminum frames.
Thanks, is there a method which they use vacuum chambers in casting to avoid air traps(voids) and also a compressing process? I don't know the right keywords but if there's similar and highly efficient ways in casting could you mention some, I'm curious to know more
Yes, there are vacuum casting methods, but those are usually done because the metal being cast is reactive with the atmosphere and would make a scrap part versus entrap gas. Depending on the material, you can use Hot Isostatic Presssing to close voids in castings. This is an expensive process, so usually reserved for use on expensive materials (titanium, nickel superalloys) in critical applications.
How do you compare 130,000 psi austempered ductile iron (ADI) vs forged steel? Apparently, ADI is about 45% stronger than welded forged steel at least when it comes to similarly designed bench vises. For example Yost brand vices make vises in both ADI and forged steel versions and they claim that the ADI is 45% stronger. Thank you for any information!
Awesome video! Totally explains why the EJ257 motor in the current Gen Subaru WRX STi suffers from cracked piston ringlands as the pistons are cast aluminum alloy. Too bad Subaru didn't want to dish out the extra dough for forged internals!
@@happydappyman well since they’re hot 99.9 percent of the time I’ll go with forged, as do most heavy duty engines. Forged is sooo much better. Metallurgy and lubricants have improved significantly to the point of negating the dangers of cold starts.
Yes, but much more of it is kept intact. Look at his picture of a forged part, and imagine machining it to clean up the edges. You'll still have most of the grain structure matching the profile of the part. It also has the added benefit of reducing the machining required.
Most Rugers are all cast.....hardly known as 'lacking in durability' in their assorted pistols or revolvers.... (But, yes, for small parts, most prefer forged/tool steel parts...
So if I understand correctly, if you just heat up the cast iron (during the manufacturing process) and then forge it, it will then be forged iron? Right?
I prefer cast steel firearms over cheap Aluminum, and that Polymer garbage. But I would love to own a milled or forged steel firearm. Still love my cast steel.
LRZ98 GAMING No dude. It’s a supposed to be a humorous style comment. A Car Guy joke. Would love to own the Diesel version and convert it to gas so I would have a very strong block! But if I made the engine the way my comment says, then I wouldn’t need the Diesel version!
Nice. Are all hot rolled steel automatically are forged steel since hot rolled steel are also compressed like forged steel? Also what if you cast it but you anneal, then harden then temper? Will that be then as tough as forged? Thank you. God bless.
Yes, hot rolled steel is technically forged, but industry does differentiate between rolles and forged due to the mechanical reductions involved and directional effects. Rolling is more akin to just stretching the material to a smaller size. Casting + anneal + harden + temper can give you something as tough as a forging with the right base material.
There are some processes that use induction to stir the metal during solidification, but this is done with a high power inductor. It doesn't direct the grains around corners.
I used to buy aircraft structural assemblies and I can tell you that landing gear were always forgings. So was the titanium center wing box for the swept wings on the Grumman F-14 Tomcat. Every forgings buyer in the aerospace industry would say "Porosity vs. grain flow" and grain flow always won. Look at the difference in price between investment cast and forged irons in golf sets. The forged irons are always hundreds of dollars more per set. Good and great golfers NEVER use cast iron clubs because the forged clubs have a better feel at impact (in many cases, a softer feel) and allow better golfers to work their shots. I play with forged irons and my .45 ACP from Springfield Armory has a forged slide and frame.
@@paulconnors2078 again, as a metallugist in aerospace, it depends on the application. There are uses for both. Sometimes the forging is overkill and over priced for what the part needs to do. Buyers don't spec out the production process for the part, the design engineers do. Castings can be designed and produced without porosity. It just depends on the application, process, and the price point that needs to be met. Go look at your car, most of the metal parts are castings: block, heads, pistons, transmission case, control arms, brake calipers, brake pistons, brake rotors, differential carrier, differential case.
@@timbarstow5939 Yes, a lot of car parts are castings and almost every part you mentioned is not one where real stress and force are exerted and few of them are load bearing parts. As for your comment about castings not having porosities and voids, I call bullshit. Brake rotors now are made thinner and thinner to meet CAFE standards and are so lightweight and are so cheaply made and so devoid of material that they are no longer capable of having the faces machined because there isn't ENOUGH material remaining to machine even .015" of an inch to smooth out the scorings of the face after the replacement of a single set of non-metallic brake pads. When I replace my rotors WITH EVERY brake job, I do so with American made parts because the aftermarket rotors cast in shitholes like India and China are so bad that the rotors warp, crack, wear unevenly, pulsate and cause other problems. And yes, I know forgings can be overkill. Before Boeing shut down the C-17 production line in Long Beach, CA they did a strength of materials analysis on every structural casting and forging used in the airframe and determined that more than 2,500 separate parts (both castings and forgings) could be more quickly and cheaply supplied as hog outs. They then proceeded to supply all remaining C-17s to be delivered to the USAF and foreign military customers with the forged AND cast parts that they determined to be un-necessary deleted and replaced with machined parts from plate, bar and billet. BTW, Mr. Metallurgist, your comment about parts not being speced by buyers, but rather by design engineers was both gratuitous and offensive. I can give you hundreds of examples where I had to correct the written instructions by mechanical and structural engineers to forge shops, foundries and machine shops because these same overpaid engineers couldn't string two independent clauses together to form a complete compound sentence and thus proved incapable of communicating effectively with our suppliers. Most of the engineers I worked with at places like Hughes Helicopters, Lockheed and GE Aerospace were functionally illiterate and socially inept bores. And likewise, the metallurgists I was forced to deal with were sanctimonious and self-righteous and they looked down their narrow noses at we mere mortals in procurement with condescension and disdain. As for buyers NOT specing parts, I have the honor of helping design the two piece large sand castings used to form the bore sighting test fixture for the 20 mm Gatling gun in the F-15 Eagle. The mechanical engineer charged with designing those two parts didn't know anything about casting manufacturing processes, the material to be used and deferred to me to make those recommendations. I speced out both the aluminum alloy and the type of castings to be used. I did that without an ME degree and to this day, my name is on those blue prints for those two parts. I later also selected and contracted with a large machine shop to finish machine and assemble the final assembly prior to source inspection, NDT and delivery to the USAF for installation in their Avionics Intermediate Shops at the base and depot level. The gentleman's video above about the strength of materials is a good one because he explains the differences between castings, forgings and hog-outs in an easy and simple way, making it easy for laymen to understand. I know the differences and have for more than 40 years in aerospace and commercial procurement and it is why when I purchased my first .45 ACP pistol, I did so from a company that guaranteed that both the slide and frame were forged. The same applies to my golf clubs. I am a 5 handicap golfer and my irons are FORGED, just the way I like them. Strength of materials counts and if you demand strength, and overall quality in manufacturing, a forged part, while more expensive will always yield better long term reliability. You get what you pay for and I am willing to pay for the best and that which will last the longest.
why do forged 1911 frames cut out the area around the slide stop pin--to prevent cracks in the frame from developing. Why is this same part left fully intact on cast frames? I guess the cast frames just don't crack...
@@generallobster usually a forging is less elastic than a casting in the same material. The energy put into the stop has to go somewhere, so it goes i to the frame. Looking a some of the cracked frame pics, it could be a machining issue with the inside radius on the slide rail, or it could be from the pin. If you have a pic of the crack cut open, it will show the type of crack, where the crack started, and the mechanism of how the crack traveled.
Most small gun parts are not cast that way. The new process is "Powdered metal". Just as good as foraged. I made fixtures to machine powdered metal parts and they really repeat. I also have worked with cast steel parts and if you need to weld on them the area near the weld gets so hard you cannot machine it. Not a problem with forged parts.
This absolutely did NOT feel like a paid advertisement! I'm just saying, in case you were wondering, I don't feel like I just got done watching a commercial, for which the company name was stated SEVERAL TIMES as being superior to all others. Just saying, that's not the reason I'll never watch another video from this user, that's all.🤷♂️
One of the reasons GM and Ford vehicles are such shitboxes is that they almost exclusively use cast parts. Imagine casting a turbocharger, one of the most high-stress and high-temperature parts of a modern engine. Yet most American auto makes do it, and Chevy Cruzes and Ford Focuses are blowing turbos left and right. Toyota actually takes the time to forge their important components, and they're arguably the most reliable auto make on the planet. It's no coincidence, either.
The tv adverts for cars are so stupid. I wish they would mention things like you have here. Such as: Buy our cars, the parts are forged and cnc milled for precision and longevity!! But instead we get the car flying to mars with a dog driving it or alike.
Casting is for disposable tools like arrows and ammunition. Forging is for reusable tools like axes, firearm parts, swords, and car parts. Using forge for something like arrows or disposable tools is a waste of good forged steel.
The Ruger Redhawk and Super Redhawk are both cast as opposed to forged; are they known for lack of durability or their inherent fragility? Nothing wrong with a well-done casting.
@@mdd1963 Gun frames and receivers don't really get the same stress as something like the bolt or trunnions on an AK. Castings are fine for low impact parts
Then why Cheap 1911 like Rock Island and TaUrus are cast iron made a bad gun yet sell to masses. What is the scientific proof cast is bad thing or this just a matter of opinion and not necessary fact?
i think it is rolled and pressed and other fun stuff? Whereas cast is liquid poured without the specail hardening and grain making processes.Just a guess.
This is all fine and dandy but today MIM has taken over those traditional methods. Metal Injection Molding. A complex process of stages using powder to a final product. Its plastic injection molding done on a wider scale using a variety of metals and other materials. Smaller more complex parts can be done faster and more economically that are close to or just as good as traditional methods. Final machining of MIM parts is sometimes necessary to meet required specs. Hate using Wiki but it does give the basics of what MIM is. en.wikipedia.org/wiki/Metal_injection_molding

There are some processes that use induction to stir the metal during solidification, but this is done with a high power inductor. It doesn't direct the grains around corners.
Amazing
as in steel mill big blocks ha they make good grain flow?
In some way cast piston for 2t is better.
It's lighter, less expand when it's warm up, less chance for cold seizure.
What do you think of LRBs hammer forged 8620 M14 receivers?
So did the original video get demonized?

The point of cast iron is for you to put different materials to fill up the gap and make the cast stronger right
Polymer frames work well I think any steel cast, milled or forged would be better than plastic yet polymer guns last for decades.
Gun owner in Hawaii? I feel bad for you as a Californian! Great video!
Does heat treatment affect the grain structure?
This is a horrible explanation and comparison of processes. "Billet" he describes starts life in a casting processes.
Great explanation but its disappointing casting is weaker
Take a look at a Ruger handguns investment castings strong as a tank.
Yes but I think this isn't true for heat treated parts? If you heat your piece again, then it's a "reset", grain will start to form again
$1800 M1A has a cast receiver 🙄 crazy
tanks brah!
