#GM #Castings #Celestiq
A couple years ago I had no clue who "Sandy Munro" is or what he did.... Today I can't wait for the next Munro video to drop. It's not just Sandy.... no it's the entire group at Munro. Thanks guy's and gal's for all you do to entertain, inform and educate those of us who didn't even know we were missing it... Thanks
You have a fantastic channel name! It should be a show.
@@crtmojo2705 Well thanks, cause that's what I intend... I am a hobbyist with a cnc machine and laser cnc... I just need to find the time to get the channel going. 🙂
@@ScrewThisGlueThat sounds perfect!
Same here
Please do a show on metal fatigue, especially aluminum components of automobiles. Also, how corrosion affects aluminum parts and reactions between differing metals of those parts. I see a lot of aluminum being used now in cars and it would be nice to know how this material will fare long term. Your show is always educational!
I have a Audi A2 from 2002, it has 240000km and it looks new. The aluminium chassi/body that my Audi has is rock solid.
Sealing between dissimilar material is how aerospace solve this issue. We have been using superplastic forming for decades in the airplane business. Aluminum airplanes can last for many decades given the right maintenance. Look at the B52 which are still in service.
Plenty of aluminum suspension components for decades now!
@Chumpster Aluminum form an oxide coating as soon as it is exposed to the atmosphere, this coating prevents corrosion. Al parts are often treated with a conversion coating such as alodine and anodize plus paint. Al can out perform steel with respect to corrosion and rust.
@@Liberty2358 re: "Sealing between dissimilar material is how aerospace solve this issue" exactly these problems have long been solved. what most don't see is simply how they are ignorant to these developments and are essentially playing "catch up". also ref: 3M.
The generosity of sharing the knowledge of yourself and your staff is something to be proud of Sandy. By taking this approach you have no doubt raised the profile and relevance of your business, however you have also entered the world of a super influencer. I suppose using UA-cam has enabled you to be a very relevant voice. Agile design practices are becoming so important in this period of rapid change. Well done!
Never get tired of listening to Sandy. Easy to understand all these techniques.
No lie those 3D printed parts were pretty cool. Imagine finding that heat exchanger back in the 1940s and you'd for sure think it was alien tech. Also exciting to hear NASA is looking to use 3D printing for missions to Mars.
Exactly!
Alien 👽👽👽 tech for sure!
This what makes the future exciting!
I'm not involved with manufacturing or the car industry, but videos like this are why I listen to Munro Live and love the way Sandy eplains things so I can understand them. I'm a few years older than Sandy and must admit my grandfather got involved in the car industry in 1910 and my father worked for him as as his service manager so I always had a love of cars and planes (my father's love). Sandy, thanks again for this channel and to Corey for convincing you to give it a try!
More of those 3D printing techniques please. Awesome content!
Before I started hearing about sending Monroe on Tesla products I never heard of the gentleman. It is amazing how much this man isn't been involved in and how many products he has helped improve throughout his lifetime. He is one of the world's best kept secrets and has taught me a new way of thinking as far as engineering. Especially the line the best part is no part to keep things functional and simplistic. Do not over complicate anything unless it absolutely has to be complicated, and then there's always ways to decomplicate it before the final product it's the market. I am no spring chicken, but I always love finding out a new point of view and a way of looking at things. Thank you Sandy! 🇺🇲
I work in technical sales for the largest green sand molding materials supplier in the world. Have you ever took part in an AFS (American Foundry Society) Congress/show? I think it would be great to have Sandy/Cory as keynote speakers at this yearly/ bi annual event and cover the technology shifts in the casting industry, winners and losers. I have been screaming from the rooftops for half a decade after seeing my first model S rolling chassis that our industry is in for a world of hurt.
" I have been screaming from the rooftops for half a decade after seeing my first model S rolling chassis that our industry is in for a world of hurt." I have no idea what you mean by this...
What do you think the winners and losers will be?
@@michaelabsher8341 If you look at the rolling chassis of a Tesla in particular as Sandy noted it has next to zero sand castings. The only ones that are evident are the 4 brake rotors, other than that they are either die castings or forgings. Compared to a legacy ICE vehicle this is nothing.
@@dokster100 Winners are die casting foundries and the equipment/materials suppliers to that industry, losers are going to be my industry, sand casting.
Finally Sandy again! I love his team but the videos with Sandy are my favorite 👍
Same, I am here for sandy.
I like Carl!
Dear Sandy, on behalf of my Italian ancestors, I want to remind you that before lost foam, there was the more precise and fine featured lost wax process,, which, incidentally, is still used for some low-volume fine jewelry casting. Thanks for the opportunity to remind your audience about this "fourth" casting process. Also .... next time you visit China ask to see some "ball within ball" and "chain" carvings, obviously a slow, low-volume process, but a worthy predecessor of 3D printing and in many cases, producing a finer finish and demonstrating greater ingenuity in production planning. The 3D printed samples are merely modern copies of the Chinese craft.
Thx Karen
Love these videos! Kudos to GM for pushing the envelope in manufacturing. Cant wait for Sandy's take on the Celestiq once it comes out. I'm sure GM will at least give him a chance to borrow one for a few days.
Sandy & Munro & Associates tear cars apart, so it will have to be a purchase or a donation.
Thank you Sandy and the Munro TEAM! I hope one day soon we are proud to see Made in USA again.
Great vlog hooray for gm pleased to see them stepping up for the future 👍👏👏👏👏👏
SANDY!! You the man brother!! I am thrilled for your amazing talent to be showcased in the UA-cam world !! KUDOS to Corey- he is the friggin future! Just 60 miles away on the Bluewater bridge!! All my cousins are from GM in Windsor!! I am sure you are well aware of marathon euchre and drinking beer in Windsor!! Your content is awesome!! GIDDYUP!!
Japanese have been using aluminium suspension and sub-frame parts for a long time. Pressure or high vacuum die cast is the way to go as it minimises or completely gets rid of air bubbles and ensures good grain in the metal.
15:10 worked at a factory that had industrial screw presses for pulp. To make sure they had the tight tolerances between the screw and the cylindrical mesh, they would build up the screw edge. An semiautonomous welding machine would heat up the edge, weld on filler material, cool down the edge, then grind off the excess as it was slowly rotating the screw.
I can easily see something like that with a Kuka robot arm making and grinding/milling turbines
That's fascinating!
Another place you will see 7000 series aluminum is in bicycles. Although carbon fibre is present in frames and rims, the aluminum is needed for things like brake calipers, hubs and derailers.
Very interesting, especially about additive manufacturing vs a huge parts inventory.
Thought provoking, thank you!
Outstanding channel. My son is a chemical engineering major who aced his ACT's. I send him all of your videos. He loves the way you handle problems. No BS. He's learning management nowadays are all robots who can't think outside the box.
Thanks Sandy and your fantastic team for answering my request about 3D printing. Have a great Holiday.
I watched this video and THEN read the article on the new caddy design, which made it so easy to follow and understand! Thanks!
We use superplastic forming in aerospace, titanium and aluminum are used for complex forms.
Good to know the General is still willing to learn some new tricks. Preventing galvanic corrosion due to contact of dissimilar metals is something manufacturers have to watch out for with aluminum. I have a 1st generation Honda Insight which is built with a lot of aluminum. Honda was careful to use Dacotized fasteners when the fasteners were steel. Dacro is a three-metal passivating coating which is like galvanizing but has a dull gray color. Aluminum will corrode around a non passivated steel fastener. You’ve also got to insulate between aluminum and steel components to prevent galvanic corrosion. On the Insight even the brake calipers, drums snd wheel cylinders are made of aluminum. I recently ran into a problem getting the brake bleeder nuts loose because the bleeder nuts are steel and not passivated. GM tried aluminum fenders on one of its Pontiac models about 1960 and did.not prevent galvanic action and the fenders rotted out furiously when exposed to salt water, setting up galvanic corrosion.
Nice coverage although video segments of each process would have helped a lot in clarifying the details.
Could you please cover 3D selective laser sintering especially as it relates to metallurgies? I was handed a part a few years ago made using that process. Similar to your ball in a ball it left me flummoxed as to how they could do that - and the finish, even interior, was as smooth as glass. I recall seeing an episode of Jay Leno's Garage where they were able to 3D scan, edit and print (SLS) a waterpump for a early 1900's vehicle they were restoring. Just stunning advance. Nothing is obsolete if you can make parts on the fly. We are also seeing parts made using Artificial Intelligence and Additive Manufacturing like the Czinger 21C.
As I understand it the 3D printed parts are "sand blasted" with flour or other soft materials for finish.
It’s truly amazing Sandy how you do these presentations in a single take with little or no editing. 😮
Phenomenal as always. Hooked from minute one and dense with information to the end. Cannot say thank you enough for all you teach.
Always a pleasure to listen to you Sandy!! Every time I learn something new. Thanks.
I love the old flying boat in the shop - a real classic! To link that to this presentation; keep an old 'plane like that in the air with traditional warehoused spares would be impossible. 3D printing and modern means of low production forming at least offer some hope.
I like the look of the car - I really have liked their "arts and science" design approach from the very beginning (even if they did copy it from Mazda.)
Great explaination of the different casting techniques, even I could understand them. The 3D printing stuff is insane!
Good point about 3D printing in space. This tech is going to be *really* important for colonies on other planets and such. If something breaks, you need to be able to fix it quickly without waiting for part shipments from Earth.
I'd love to hear more about that heat exchanger (and how it performs vs traditionally manufactured heat exchangers) and about other real parts. So often I see 3d printed parts for toys and theoreticals, not as real parts.
Several rocket companies are using 3D printed parts in ENGINE components. SpaceX has used them for some engine parts in the past. RocketLab has actually been launching rockets with 3D printed engines, and is aiming to manufacture the carbon fiber shells of thier rockets with robots. While Relativity Space wants to go to orbit with a completely 3D printed rocket. So yes, WELL beyond the old "rapid prototyping" moniker, these techniques are now valid low volume, high stress manufacturing processes.
@@patreekotime4578 I concede the point about the rutherford engine, but what I really want to know of is parts that are physically superior via 3d printing, not just "eh good enough" and cheaper to develop.
@@rhamph Heard the Chief Engineer of the Clestiq on Autoline talk about their 3D printed D-Ring for the seatbelt, its apparently strong enough it can lift the weight of the car. Any part's qualities of "Physically Superior" or "good enough" will depend on the application or use case. Cost is a huge factor though, else we'd make more things out of Diamond.
Great insight..The last company I remember using lost foam at scale was GM/Saturn. Our company has been there.
IMO Additive is really best for prototyping or super specialized small, low volume parts. Cost is crazy compared to subtractive manufacturing.
Fascinating viewing. Was familiar with some of it but the technological advances in manufacturing and repairs are impressive nearly beyond comprehension 👍😁
I used to work at an aerospace company that did super plastic forming of titanium alloy. Wild stuff. The dies were made from 309 stainless steel and heated to 1450 F. The blank was prepped, loaded, preheated, and then a rack of argon gas cylinders would blow the titanium into the die cavity at around 1200psi. After holding for several minutes, the gas was vented, the die opened, and the part put on a cooling fixture so that it held it's shape until it regained it's strength after cooling. Then it was off to be grit blasted and acid etched to remove the brittle oxide and alpha phase alloy that forms on the surface at high temperature in air. Also horrendously expensive. Cycle times around 30 minutes per part. The argon bottles had to be refilled every day. It took three hours to heat up the die and about eight for it to cool enough to handle it. The seal surface had to be polished after about 20 parts and recut every 100 or so. But when you only need 300 parts a year, and those parts go on fighter jets, it makes sense.
Thank you Sandy for a great manufacturing tutorial!
THANKS SANDY, WE LOVE ❤ THE TECHNOLOGY, AND YOUR THOUGHTS 💭😎👍💚💚💚
ALSO THE EFFORTS OF THE MUNRO TEAM
Thanks for watching!
very VERY good episode. presented fairly, and I actually applauded GM as it went. I consider that a well done presentation to a Tesla fanboy that wants to see thing from all angles. 👍
Im intrested in learning more about those 3d prints
I'd love to learn more about 3D printing / additive manufacturing on this channel~
I am a 70 year old applied mathematician who has worked in defence etc and Sandy has the right vibe. He knows where the engineering bodies are buried believe me!
So your using your pool table as a stage. Nice cover. The angle to the wall explains why you have cut down sticks. I prefer the one with the cut down shaft [probably a 15 mm tip unless it was tapered] for the greater mass and similarity in circumference to standard length at the butt. Much like the the four full splice standard length cues probably made in Canada. The other cut down might be a better jump cue? Thanks for the description of lost foam. I was not sure what that was when you mentioned it regarding the cybertruck. Seems similar to lost wax but quicker.
Great episode. Thank you for giving us a fascinating look into the new ways and materials used to build cars. 🙂
A lot of car bodies are now held together with adhesive, and to hold the parts till the adhesive cures they use rivets applied by robots. There is also high strength boron sheet steel with a 'BH' prefix, now the BH stands for 'bake harden' this allows the steel to be formed and pressed and after the car body gets painted and goes through an oven to cure the paint the BH steel then achieves its maximum hardness, this means that thinner gauges can be used to get the same or higher strength.
You forgot the 2000 series Aluminium Alloys Sandy. Like the 2024 alloy that the SEABEE (!!!) and the spars are made from....over your right shoulder at the end. Amazing stuff to form when it's in "O" condition, then heat-treat it up to a higher yield than 6061 T6. Oldschool.
Steve Stevens, I was wondering the same thing re: the pool cues behind Sandy. And, where's the table (-:
I began following Sandy through his Tesla interactions. Always great videos! Wishing everyone a great New Year. Blessings.
I spy a SeaBee behind you towards the end? Very educational video. Thanks for taking the time.
Hello Sandy. Love your videos but you may have got something wrong. The reason sand castings are heavier and have thicker walls is due to the casting process. Sand cast alloys like A319 are sometimes preferred over die casting because they are more pure aluminum and tend to resist oxidation more. Maybe I am wrong about the strength as I was in the lighting industry where there is less mechanical stress.
This is the first long video done by Sandy alone.
Very cool and thank you. I've been exposed to a few of the processes described but this was much clearer.
I do have one question though: what is the difference between super-plastic forming and hydroforming?
en.wikipedia.org/wiki/Superforming and en.wikipedia.org/wiki/Hydroforming
YES! Please talk additive manufacturing.🙂
LOVE hearing Sandy talk about AM!!!!1
sounds like U could spend the next six months, writing 4 *Design World Magazine* !
a super run through on new technologies! it's great to see some of the QC samples! good luck with it Sandy!
Like hundred of thousands of others, I always enjoy your videos Sandy. Quick footnote; I believe I spied a CB aircraft in the back corner late in this video.
12-30-2022 & a Happy New Year to you and all your peoples!
Good to see new Developments like this. I surprised Sandy did not talk out pressure moulded carbon composite. For low volume high cost items it’s the big up and coming technology.
With some recent videos I’ve seen there could a future in compression moulding stranded fibres. It would give 90% of the strength with a much reduced cost over hand laid prepreg.
I grew up in the late 60s and 70s and am happy to see Cadillac trying to regain the glory. I haven’t really like Cadillacs since the mid-80s
Munro should do fund-raiser to acquire a Celestiq for engineering analysis. I just might be willing to buy a sticker for that cause.
I knew a guy in Queensland, Australia whose business was to reproduce steel parts for machinery used in the dairy industry, parts that would otherwise take weeks to receive from the manufacturer. He had half a dozen CNC machines and could get the parts made in a couple of days. That was 20 years ago!
I love this kind of explainer on new tech. Yes! More please. Anything that is new or on the horizon.
Great overview breakdown.
Thanks for another great video. I have been watching for quite a while and they satisfy my curious mind. Seems to me that the EV revolution has made being an engineer a cool profession again.
Very nice presentation, thank you.
Sandy
I am always in awe of your life wisdom.
Carry on,
Brian
The new Cad Celestriq's styling reminds me of an old Chevy Malibu station wagon they were selling a few decades ago in the early 2000's.
Very informative, thank you.
Thanks for the lesson
I respect your opinion. Thanks Sandy.
thumbs-up seems inadequate for my love of your content. So inspired.
The 3D printing with metal is pretty cool. (Or hot…) There’s an aerospace company that is 3D printing almost the entire rocket. They had a video that went through all the difficulties with printing metal, if you’re melting dust, the laser blows away shavings and the metal gets porous, when printing with a wire the atomic structure isn’t quite right and the metal isn’t as rigid as it should be, and many others. It would be really cool to see a video about all the different ways of 3D printing metal, benefits, drawbacks, etc.
KOENIGSEGG builds a novel variable turbo from stainless steel, including the internal turbine wheel. ua-cam.com/video/DNedUZxP8NU/v-deo.html
If that's the rocket maker I think it is, after the 3d printed part is made they process it with HIP (hot isostatic pressing) to increase density and material characteristics. 3d printing is just the first step for those parts.
Hey team, awesome that you’re selling merch to buy the Semi. Perhaps it’s worth doing a Patreon and pledge x% of it to purchasing vehicles to tear apart
Because in fairness this depth is nice for some but I’m sure there’s more interest in more different vehicles instead of videos on every screw and bolt
Great industry education Sandy, Thank You!
Thanks for the info, always entertaining! Merry Christmas!
Jay Leno has said several times that a c.1950 Cadillac was the most advanced luxury car in the world, offering more advanced features and ride quality than Rolls or Bentley, etc. And he didn't just mean a softer suspension. I hope GM can make this new car a winner.
@Retired Bore Quite true, good points. On a different note: I explain to my friends that the period of 1945-70, when an unprecedented proportion of Americans could buy a house and afford to raise 4-5 kids fairly comfortably, *and have savings* was an anomaly. The US was the only intact major industrial nation in 1945. Germany, Japan, Italy, France, and Russia were devastated, especially the first two. The UK was broke. It took till 1970 for Germany and Japan to rebuild their economies - and then their cars started to roll in.
World competition is a big reason Gen X and Millennials have it so tough - and so many don't realize the era of prosperity they compare themselves to was an anomaly. (The other reason it's tough, the flow of wealth to the top 1%, is a huge reason but that's a different discussion.)
Another great video !!
Thanks
What about That Aircraft in the background? I have seen it before but what does it do there?
Like the Maurice Sendek on the wall.
I might need to disagree with Sandy's opinions on BMW styling, but he is the absolute king of mainstreaming complex industrial processes and soothsaying :-)
Great video explaining the details
Thanks
Thank-you Sandy ❤❤ Would love to know more about corrosion and rust potential in the vehicles you analyze. EVs are an expensive investment. It would be great if we know they are built to last even in places where harsh winters and road salts and worse can destroy it.
Love it. More 3d printed content please!
All ways interesting
Thanks for your time and thought
GE Aviation is doing some engine parts with additive, but you can't do things like single crystal blades with AM. So hot section parts seem limited.
Thanks Sandy for the great description of what GM is doing lately to keep up. Your explanations are always enlightening and on fascinating manufacturing techniques. Please explain what that amphibious aircraft fuselage is doing in your faculty, or the name of it to find out what it is? Thanks again and keep them coming.
@hughwaller6789 : I was thinking the same thing watching it in the background :)
Thank you!
Sandy - GREAT SHOW.... I JUST WONDER WHO USES THE POOL CUES ON THE WALL BEHIND YOU!🤔
Loved it, particularly the part on additive manufacturing. Are there any parts that could be improved using 3d Printing? Less weight / size or more effective?
If you want to know about who first did sand casting, check out Steinway. They’ve been using sand casting, to manufacture the iron plates in their pianos, for over 100 years.
Would love it if Sandy could interview the people making the Czinger 21C.
AWERSOME SHOW THANKYOU SANDY
At 11:44 Sandy shows an example of how the statue with chains called Il Disinganno, also known as The Release from Deception was created. This will go over most everyone's head but to those who know will understand.
Another great video, thank you.
Thanks for watching
Thanks again Sandy for a great video. I think GMs sheet metal forming technology for aluminum is called QPF (Quick Plastic Forming). It has a faster cycle rate than Super Plastic Forming (SPF). SPF cycles at about 20 minutes per part. QPF cycles at about 2 minutes per part. SPF and QPF can only be used for aluminum and magnesium alloys. Steel is formed using a much more expensive process called Hot Stamping. Hot stamping is very fast but has a much more expensive investment cost.
Curious about the 3D printed battery tray. Was that ABS? Also what orientation was that printed? Just about every way I could think of woul have lots of support structures
The part could have been made on an Stratasys Objet printer.
It was probably a powder bed based process, which is pretty popular amongst industrial prototyping when you need a combination of actual shape representation and functionality. In powder bed the support structure is the powder bed so many shapes are possible with relatively little post processing labour.
@@mdfyui8000 Have you seen how poor quality the parts are from those machines? I really don't think that was the machine used to print that part.
It would be nice to see Cadillac build a "Standard of the World" quality car again. They have the technology; do they have the will?
I think Cory should get a plaid for Christmas 🎄
Cory thinks so too 😃
As a public speaking teacher I give you an A plus!
Very good presentation!
I really like the foam casting seems like a very economical way I guess the repeatability speed is the factor right?
Good video, I wish it was twice as long.
