Metal Casting: Sand Moulds

[@johnnyh.6851]

I was an industrial pattern maker for 45 years, a wonderful and rewarding career. And even today, I miss it. Thanks for sharing.

a most excellent program, very educational as well as entertaining !! thank you very much for this.

[@KallePihlajasaari]

A commendable film. Adequate detail of most of the 'sand' casting techniques used in industry until recently. Missing only is the direct 3D printed sand mould. This was a rewarding half hour. Commentary was informative and not noisy shouting and repetition for attention deficit children.

[@myMotoring]

9:49 Great to see that early Stratasys rapid prototyping system and that Silicone Graphics Andy computer system. I guess this was filmed in 1993.

[@blackflagqwerty]

Absolutely fascinating video! Missed my train station because of it!

[@radiofun232]

Finally a good (!) and professional video about metal casting, after having seen all the amateurs on You Tube struggling with the process.

[@luckygen1001]

Then you should look at my channel, a cut above the rest.

[@dawnlightening]

@mostafa mahmoud Watching this video was a very worthwhile use of half an hour. Highly educational and completely engrossing. I really enjoyed it. Thank you for uploading!

[@smccain953]

This was a great overview of many types of casting methods, loved the whole thing, thank you.

[@bryangrimshaw5607]

This is a really informative video and pretty up-to-date. Just the right amount of detail even for an experienced engineer like me. Thanks.

[@ramjortan5205]

Hi Sir I'm Jayaram from India joined in casting industry this month I need a guidance from experienced professionals like u

[@topiaspoutiainen8696]

ramj ortan how is it going with the casting?

[@lovejcdc]

I don't know for sure what town this plant is but I was in Australia back in 97 and spent the night in a small town that was literally on top of the iron ore mine for the iron mill at the top of a large hill above the town. I just can't remember the name of the town grrrrr lol but it was kinda weird and cool at the same time to feel the rumble under your feet when they were blasting in the mine.

[@luckygen1001]

This video was filmed at R.M.I.T. college in Melbourne Australia for apprentice molders and pattern makers.

[@quicksheep]

Very interesting video...great summary of different methods. Thanks.

[@StuartZiane]

Fantastic overview of the different casting methods and techniques. Well worth watching these videos, even if they are 27 minutes long!

[@mikelong8762]

I work in a foundry for 15 years and this brings back bad memories.

[@JimLahey21]

Considering most of this video was made in the 90’s it should

[@SadeghShah-r4n]

​@JimLahey21 dou you know provider or producer of these videos?

[@scottleft3672]

Very informative, old, but much to learn...i did not know about the reheating and austenizing ofcast iron.

[@jackking5567]

Explains a lot about how automotive plants can produce so many vehicles. An older 1960s foundry here closed several years ago but it was a good thing even though jobs were lost. Working there was almost all manual and the place dusty, dimly lit and workers literally slaved under threat from management. Rising electricity costs shut the plant. In two years their electricity bill doubled!

[@Ericdawg420]

Jack King well i work at a place called maynard steel casting that sounds just like that. Lol

[@simex4018]

Jack, I’m wondering whether you could tell us whether PCB containing oils were used in foundry sands. And how were the sands disposed

[@bassome3000ify]

made my day, one of the best vids i seen

[@markmccastle7932]

Hot Shell resin sand molding system Chicapee molding machine. Nice to see still kn use. Shalco Hutchison is a good machine aswell. Bradley Piper core blowers are a bit antique

[@bill3641]

The Shell Process was invented in Germany ( Croning Process ) , and brought to the states after the second world war. Not long after that, it was in use in many foundries. Because of the tooling costs it required high production numbers. Shell Cores are made also.

[@KossolaxtheForesworn]

just saw the 40s iron casting. it seems essentials are the same but nothing else is.

[@melgross]

Wow! Silicon Graphics. I had one of those back then. Shame they’re gone.

[@randomtux1234]

3:14 What is the zig zag channel for

[@Flederratte]

Probably for venting air which could get trapped around the core

[@splint3048]

@@Flederratte Yes it's definitely a vent as the expanding gases inside the core would cause porosity in the casting if the vent was not there but I'm unclear as to why it has a zig zag path.

[@AppliedCryogenics]

Lucky guy gets to make sand sculptures all day.

[@ymanuelbewithu3735]

But where is the gate pecker?how they remove the molding parts to separate.only hammer they used???

[@yelaverahul5067]

What do you mix with sand?

[@udikatsu3240]

I want to work in this company how to apply? I have experience in this casting field for 5 years working in Japan. please help because I am in need of a job to support my family

[@Foxtrot2F]

I don't understand, why he says, that "8t. of metal for risers" is not wasted, when actually it is wasted? Energy requirements for them to be melted again is way more higher than cost of ore itself.

[@Eddiecurrent2000]

Ore is cheap, making it into iron isn't.

[@enhaxed7839]

Wow the original source for 3d printers right there @ 10:18

[@rock3tcatU233]

Wow, they even had 3D printing.

[@robc3056]

no..now we have 3d printing !!

[@myMotoring]

Great to see that early Stratasys rapid prototyping system and that Silicone Graphics Andy computer system. I guess this was filmed in 1993.

[@markmccastle7932]

Wow haven't seen a Hunter in a good long time

[@Greippi10]

16:20 (4:20pm ololo) "Hotbox moulding" 42069 blazeitup!

[@hughmac13]

Hmm, there could be a big future in the consumer market for that "rapid prototyping." You never know…

[@johnbattista9519]

Hugh MacDonald , rapid prototyping has been around since the 50’s as far as I remember.

[@hughmac13]

​@@johnbattista9519 I was being somewhat facetious in my assessment of the small-scale, computer-numerically-controlled rapid prototying shown in this somewhat older video-as I think you detected. I'd be interested to know which technologies were being used as many as 70 years ago for rapid prototyping like this.

[@johnbattista9519]

Hugh MacDonald , look up solid free form fabrication.

[@csnelling4]

Hard toil in those days.

[@markmccastle7932]

A Difion in working mode

[@afbennett3038]

2:55 hehe

[@the_real_bin_chicken]

Strayla!! before the stooges in Canberra forced our industries overseas.

[@morgorth3242]

nice indigo computer

[@LukasDubeda]

One thing I haven't noticed in this setting was that there was not a single one strong, independent feminist woman. I thought they demand equality and proportional representation in the work force.

[@donaldbuchan4387]

They can only hire women if women apply, a smart woman would steer clear of this industry. At times I wish I had.

[@theonlybuzz1969]

How did you know that there was no women involved in the mould industry? Some of the places was dimly lit that you couldn’t identify what the sex was never mind if human at all! I had friends who had a lifetime in a foundry and that was only in 5 years or so ! Great video depicting the different types of process, I really enjoyed watching them, be safe in 2021 !
