In the video "making a casting model" I have shown the first step of how to get an cast iron wheel. Here ist Part 2 with the molding and casting process.
Started working in an Iron Foundry on my 18th Birthday. Seen some tough guys come and go. Some come in and are told to come back with Steel toed boots and they never return. Call that a healthy choice for some. I’ve seen iron accidentally poured down a man’s boots and things of that nature. We’d make the copes and drags in the morning and pour in the afternoon. That job will make you tougher if you’re tough enough to hang in for a few months to begin with.
I worked in a foundry as a metallurgists assistant in college and the smell of hot sand gets into your hair and skin and it takes weeks to get out. there is a smell of hot casting sand that you do not ever forget.
I worked at The Chevrolet Grey Iron Casting as a sand wetter. Great place to work and in it's day was the largest Grey Iron Foundry in the world...COOL. She's casting Aluminum now using the lost foam technology. I left when the iron left.
I never worked in a foundry but I did work at a pattern shop and made a lot of that stuff. I've seen patterns larger than cars. mold boxes 8 feet tall and 15 feet square.
Great video thanks for sharing it and I'd also like to thank the company for allowing you to film. Those guys are true professionals and make a great team.As someone who's done some sand casting work in aluminum it is amazing at how easy they make it look.
I have noticed that in a variety of skills. Once people are competent and confident there is a relaxed aspect to the work, they "make it look easy" as the saying goes, but as you say there is knowledge and experience there.

Here in the usa that red stuff they are washing the mold with can be expensive. Not sure of that type exactly but the ones for stainless/steel are ;) You would think they would just wash where the molten metal would be hitting the no-bake sand. That excess on the mold adds up really quick.

That was interesting to see the foundry I worked in had a machine to make the mold called the molder 2000 degrees was pouring temperature that's the kind of ladles we had
40 years ago for me James. Did it for a couple of summers while in school. Can you still remember the smell? And the foundry dust getting into everything? I'll never forget the smell of a foundry.
@@johnk1955 I really hope you gents were issued with and wore more protective equipment than what we see here...it is virtually non existant. No hand protection while using chain shackles that have pinch points everywhere. The smell you speak of from organics in the Furan sands which emits nasties when heated. If you weree not subjected to medical assesssments over those 40 years make sure you are checked regularly. I was fortunate enough to work in industrial processing but the employer always adhered to strict Health and Safety regulations.
i'm watching this video to try to figure out how my relative died in the 1920s when a furnace blasted while he was trying to set the stop in the ladle. this was the best visual I could find of the steel being poured into a ladle so it definitely makes more sense now. before the days of ppe or even having the slightest care if your employees got injured or died on the job.

Nice, missed this in college industrial tours decades ago. nice soft, effortless, clear, almost musical way of speaking too, are you Luxembourgish? the river "sure", in "grippingham"?
Although very interesting….my thoughts are with the workers and their health who are not provided the proper safety clothing to include face masks, protective gloves, aprons, and etc. I now understand the importance of the laws of OSHA.
That s à very interesting video I did not understood that the sand do get hard.. I work in pianos so iron "plates" are not new to me. But there are cooling deformations and stresses in our parts. However on those wheels the precision looks a little " crude" , I guess they are machined later to get to the nominal dimensions.
great work,the work is extremely relaxe and the workers are so so experienced in sand casting, i have some questions? what is the type of this sand mixture? what is the suspension 5:35 what is the type of molten steel
If the materials used are properly dry, there shouldn't be much splash anyway. Most dangerous are the temperature lances you see at 8:18. They are wrapped in carton and the water in there evaporating throws drops of iron in the air. After tapping the melt is genereally not terribly hot (1300 - 1400°C), so the reaction is somewhat tame. At the furnace the melt goes up to around 1550°C regularly, so there are many more drops of the melt flying around when checking temperature. Also, at 1550°C the melt is radiating so much heat, that you acutally want to wear long sleeves during deslagging, but that also depends on the diameter of the furnace. Whilst your body is alright with the heat, your arm is heating up really fast. It tended to burn the skin on my little finger, cause it was heated much quicker then any other part of my body. It's a fun job though, i really like the look of the liquid metal. I can still be amazed by looking at the melt for hours :)
8:46 reminds me of the Foundry level from Tony Hawk's Pro Skater 3, yeah I was looking for Tony Hawk's Pro Skater 3 Foundry in real life and this popped up lol
Excellent video and narration! Very interesting. I am guessing that this company will be forging the other main parts to your cannon also? Must be very expensive? Thanks for sharing!
Great too see but seriously the PPE has a lot left to be desired!! I used to work in a cast iron Foundry and I worked directly with molten metal and there's absolutely no way we would get away with wearing a short sleeve shirt. Just saying
How to reuse the sand which is already solidified block by resin? Do we need a crashing machine to crash sand block? Is it easy or difficult to reuse if we use resin in the sand? Thanks,
Basically all of our sand was reused. Some of the sand can be made hard enough you need to use a jackhammer to chip it out. It’s all thrown away. The molding sand was never that hard. The center core sand typically burned up and was returned in the system.
I work in a foundry like this, and yes they should be wearing more protection. I wear a hard hat, earplugs, eye wear, a respirator, 2 pairs of gloves, steel toe boots with metatarsals, and coveralls. It doesn't matter what part of the foundry you are in we still have to be fully protected. It's quite nice working for a business that wants to keep us healthy and happy as possible so we can enjoy our golden years.
Hello T12J7: According to what I read in comments here, a one Laura Bartlett (below) states, "He is adding inoculant to the iron in order to form the correct microstructure of flake graphite. The inoculant produces 'seed' particles that help graphite grow instead of hard and brittle iron carbide".
I need to know how a pulley with fancy curved spokes is made. I see them a lot on antique machinery and church bells of iron had giant iron pulleys attached to them to swing them in America. Could you tell me how it was done? I beleive it all was cast in one mold and no latheing done to make the groove in those big pulleys.
The shaped of the patterns determine the final product. Usually complex shapes used a lost wax process where the finished part's shape is held in place by a wax core that melts as the iron, aluminum, etc is added to the mould.
I wonder if spraying your piece with a light coating of mineral or cooking oil would help it come out of the mold when the mold is initially formed or if that would be a bad idea.
We were told to spray the patterns with oil so that the mold would not stick. If sand sticks to the patter it becomes part of the pattern. This happened to me and I did not notice it with the result that a number of my pieces had to be sent to the grinders to have the bump ground off. This was at Lancaster Malleable in 1973. The parts I was making were for commercial oven doors. I was paid 3.23 an hour while the grinders were paid 11.00 an hour.
Oh yes i remember the smell it was worse when we used furane and alpha set that burned the throat raw when casting out . bloody hard days. I couldnt do it now . green sand was the best to cast with always was . although in ten years green was never the colour.
That’s some really slow molding. I never realized how spoiled I was to have those patterns back in the day bolted and ready to switch in just a few minutes.
yet its everywhere! most of the industrial machines like lathes and drill presses milling machines are made with it, pretty good at damping and easy to cast!
Und wer es nicht kennt sollte sich bei Gelegenheit so ein Werk mal anschauen damit er eine Vorstellung davon bekommt wie stark es dort nach Lösungsmittel stinkt durch die synthetische Bindung des Formsandes.
Great Matthias, I enjoyed this very much. To me molten metal and especially iron is very beautiful. 5:30 you say "this reddish liquid is a suspension of (something)" just curious what that was.
@@matthiasburger2315 chamotte (grog) does not have alcohol base. What alcohol base is added to chamotte? To soften the chamotte, they mix with alcohol instead of water? They can soften with water also. Why do they use alcohol based? Thanks
I got a story I want to tell you I was on clean up crew I also was in charge of fire extinguishers one of the molds was on fire the flames was getting pretty hight I though it might catch some electric wires on fire frothier down the line so I though I would use a fire extinguisher I never used one of them before I field the whole foundry with a thick smoke and the big shots were taking a tour of the place I thought I'd catch hell for that one but no body sad anything I got away with that one and the big shots seen it all
I’d imagine there’s a lot of different options. One we used the most was nickel. It’s been over 20 years so I don’t remember what some of the less used items were.

That guys are doing an increddible hard job. I hope they get paid properly!
That factory has some age, but the quality is still way, way better than films of the modern Indian and Chinese factories I've seen.
There's something beautiful about how molten metal flows.
I never worked in a foundry but I did work at a pattern shop and made a lot of that stuff. I've seen patterns larger than cars. mold boxes 8 feet tall and 15 feet square.

Very interesting. I would wear a mask if I worked casting a mold.
Silica is no joke
Just perhaps they have health insurance that pays them more if they're sick (need to stay at home) than they earn working.
Here in the usa that red stuff they are washing the mold with can be expensive. Not sure of that type exactly but the ones for stainless/steel are ;) You would think they would just wash where the molten metal would be hitting the no-bake sand. That excess on the mold adds up really quick.
Lowell Roemer what is that stuff exactly?
Loved working in iron foundry, was a grinder for couple months before i moved up.
I'm glad there was a follow up to the first video this is a really cool series and man do they have some good music playing. Again really cool
👍 Making good casting has been and continues to be a matter of hand skills ..

@@annesiac3265 Sorry for your loss. That would not have been a pleasant experience.
Thank God I work in a modern Iron foundry where our Molders use patterns/cores/ pinlifts to make a mold....Give kudos to these guys though.
Yea no kidding, the foundry I work for can produce over a thousand castings per shift. It's really cool seeing these guys do it by hand though.
I feel respect for those working in that foundry

Keep these video's coming, Matthias
Very realistic for what happens, Sufficient to learning.
Wait, so they have a resin pre mixed with the sand that hardens when condensed or when it meat the airs?
When it meets the carbon dioxide in the air specifically, the resin is called sodium silicate.
Nice Work
Such a small foundry thats crazy.
Love these video
Very cool video! I feel like these guys should be wearing dust masks... are safety measures like this less regulated in Europe?
John Aldrich in india worker does not wear helmet hand gloves mask and any other safety equipments!!!
use to work conditions, it was ok,still had safty cocerns but greatr fellas to work with,and we make food,maybe a drinky once,.
would like to see more on sand compacting. does this resin almost completely eliminates the need.for compacting?
So so so cool !! thank you
