That is the most elaborate setup I have ever seen. Most commercial setups don't even have any hydraulics and you have a dedicated one just to lift one mold off the other. There must have been a sale on hydraulic rams.
Its based on a jolt/squeeze machine, very comon simple machines used in most small foudrys. Most factories ive worked in do infact use lots of hydraulics and heavy machinery. For my machine i just used cheep pneumatic/air cylinders from ebay and a stick welder. It gets used daily so its worth the investment to me, and asking somone to work on the floor with bare feet is just unacceptable here.
Cool homemade setup for a home shop. I used to work in a DisaMatic foundry and those high production machines are incredible to watch. We had some patterns that would produce 30 pieces and it would take about 6 seconds to make a mold.
OMG! Dowel pins with threads. Now I have seen everything. 8 minutes a box - not bad. But with small moulds and a nice little pattern plate like that I reckon that in my heyday (long since gone) I could have equalled and maybe even beaten that. Possibly to 6 or 7 minutes a mould and I would have sieved the first sand to improve finish and moulded in a proper tapered sprue. But to show you just how slow we both are I have a book - “Foundry Practice” by R H Palmer, published about 1911, that has a time study. Its for a 13 inch by 17 inch mould with a 4 inch high drag and 4.5 inch high cope so it’s a much bigger mould with lots more sand. Entirely hand moulded 4 minutes 20 seconds and machine (power squeezer) moulded 2 minutes 10 seconds. Now that is moving - those old timers really worked, doing that for 12 hours a day 6 days a week, no wonder they did not live long!... Martin PS What do you use to convey the sand upwards?
I only use oil bonded sand (mansbond) it costs a lot more initially but it gives a very fine finish much better than regular green sand. And it needs no venting at all! Ive just seen your video on how you rework your sand! Wow thats a lot of hard work! and exactly the reason i made this sytem and only use oil sand now. My machine lifts the sand with an arcamedes screw from the hopper and works it to a very fine fluffy techture when it drop down, and so does away with having to grate it through a sieve so saves a ton of work. I then just wait untill the molds are cold in the morning open them on a shake out table with a grate on top and into my muller that is simply a cement mixer with 3 6inch iron balls rolling inside it. I still have to shovel the sand from the muller to the feed hopper but that the last bit to mechanise. And yes exactly what you say, Im 35 and get a sore back already and will probably need to work for another 40 years before i can think of retirering lol.
Part of the reason for your perfect molds is your perfect pattern. Really good job. You really cut down on secondary work by putting in your runners, well and sprue locations. Just have to complete the sprue and your off and running. Very good.
Thank you, im still learning a lot about pattern design, the machplates realy do speed things up when making multiple parts so there well worth the investment to me.
@@cringleengineering7688 can you do a video just on the sand? What you use, how long to dry, stategy for using vents etc aimed for people like me that have no knowledge at all about casting?
@@therealspixycat i have had a lot of questions regarding the oil sand so i will make a video showing the whole process of using the sand soon. Just waiting untill i can purchase some new sand as it would be usfull to show in the video.
Not to make you feel bad but we had a molder named big Jim. He asked th boss if he could take off at lunch with full days pay if he got 125 14x16 molds done. The boss said sure, as he laughs. Well big Jim went home at lunch with full pay. He was using 2 hands flipping a 14x16x8 deep flask, full of sand with just his wrists. Now you have a goal😁💪 Great job by the way.
Job and knock always helps production! I met simular lads working in an abotour, 250 cows and go home! But i bet big jims back regrets it now, il bet he also got a wage that afforded him a pension and house. Work smarter not harder is my moto :)
@@cringleengineering7688 no problem, if you can give more specifics like weight, or 1. list the machines needed by name 2. Show how to engineer/make the plastic parts you use to make the molds, 3. Specifications for how much sand to oil I would highly appreciate it. I desire to make all of my own parts.
I'm a bit new. With your setup for separating the two halves why not have an automated cutter for the sprue? 4:58 (I think sprue is the term?) Also while automagically cutting the sprue why not run something like a step drill bit to create your funnel? this might reduce your process from a 7 min to a 5 min by automating more of the work, reducing tool changes, and work location changes.
As with most things its all down to time and funds, ive spent the time and money i have available and this was the result. Im sure could design a better even more automated system. I couldnt think of a cost effective way to automate the sprue cutting as each different pattern has different hole locations and at the end of the day its a matter of seconds and im more focused on removing the more labour intensive aspects for now. Thanks for watching.
I always carve a pouring basin on the top of the cope. I never pour directly down a spruce. It does things such as final filter of impurities and obviously slows the metal speed down like rip rap in a ditch. We were all taught this by one of the finest foundry men in the business, Dr. Paul Spidel of UW-Stout. You might want to include this in your repertoire.
I have tried adding a basin but i have found i just dont need to bother. I can controll any inclusions via speed of pour so air cant enter, and using sacrificial risers to remove any turbulance and trap oxide and slag from entering the runner and gates.
The YT Algo must've randomly decided I watch a sand casting video... The funny thing is, I did some of this, years ago in another life. The process you've put together is fantastic. I could see how it would lead to consistent quality casts every time. Great job. Now back to regularly scheduled programming....
Thank you for your video ,Amazing set up.What type of moulding sand/material do you use I was thinking trying petrobond sand . I'm trying to making a permanent mould for my art sculptures, I have used fine sand and cat litter as a home made alternative but the detail isn't good enough.
Probably best not let the work-experience lad use it though, that pneumatic ram looks like a great way to get a smooshed hand! the biggest benefit that i can see is the sand delivery system, there's a lot of time used up in scooping sand. the biggest downside that i can see is that you're restricted to using a single size of flask, but there's also something to be said for standardizing on a single size!
Ah yes if i do get an apprentice i would have to make it with a second switch so both hands have to be clear of the table to opperate it. It does save a lot of effort moving sand and did away with having to seive also. The mold spliter actually improved results the most the rest just saves labour and speeds production.
Thank you, the excess sand falls into the large yellow bucket seen under the bencth and is emptied back into the hopper feeder manually. The results of these molds can be seen in my other video.. ua-cam.com/video/wTpeDJuHA4g/v-deo.html I will add more casting videos soon, thanks for watching.
this is pretty neat, but what for of material are you ucing for the pattern? Even if that was steel, i would think you would get some sort of deflection in it from compacting the sand since it isnt sitting on a flat base and just sandwhiched in. i know you cant get perfect tollerance in these molds, but how are these parts dimensionally?
Thanks, my patterns are mostly 3d printed plastic on plywood(see my other video on making of the matchplates) there will be some spring in the patterns but only a fraction of a milimeter probably less than the thickness of the paint so realy no isue at all. Ive been told many times my castings are nicer than most other available casting kits so im more than pleased with the results.
Nice setup, equipment, and process. You do good work. The only thing I could think of to make it even better would be to have the excess sand during mold prep go or fall back into the mixer so it just keeps recirculating. Since mixer is large and probably wouldn't fit well under the press for gravity return, maybe a simple conveyor belt. Anyway, I love to brainstorm, lol. Cheers.
Thanks, im still working on automating as much of the sand moving as posible to save my back and a sand return conveyor would be great but just not worth the investment currently.
@@cringleengineering7688 yeah, I totally get it. One improvement at a time as it makes economic sense. When the time comes though, with your skills I'm sure you could build a simple conveyor out of mostly found parts.
nice workshop. makes your job easier. sand casting is a tedious job. I've seen a bunch of videos from foundries likely from India or pakistan. the manual work sand casting they do is very tedious.
Awesome! Simple design! Quick process! I can see that the sand is pushed into the pipe using the hole in the bucket but what did you use for pushing the sand all the way up into the pipe?
Thank you, the sand is forced up elevator with a arcamedes screw inside the pipe. This has its own motor(the large green one under the hopper at begining of video) the second motor drives the stiring bars to keep the sand from sticking in the hopper. Bothe are operated from the same foot pedle when switched on.
What would you think about casting framing members like the subfloor joist systems as a solid single piece using this technique to save labor costs and create a template for mass production rather than individual casting and assembling?
Impressive! it seems so accurate. How do you get the sand to hold so well? Is it mixed with some kind of adhesive? And also do you reuse the same sand?
Thank you. I just use oil bonded sand (mansbond is the brand i use), it is very fine and sticky almost clay like when new. I just add a little mineral oil when mixing before reuse and top up with new. Its not cheep at around £50 for a 25kg bag but i would highly recomend it. It saves lots of time tempering sand and no need to vent at all and i dont have to wait for the sand to go stone cold before using again. One bag should be more than enougth for hobby use and would last a life time.
The machine is very impressive. I stuck around until the end of the video because I thought you would pour some molten metal. Still a great video. Do you feel like the machine was worth all the trouble to build, still today?
Thank you, i will make more casting videos soon. For me the machine was worth the investment as it is somthing that gets used daily, It takes a lot of effort and skill out of the job and it is useable by anyone with little training so i can easily get somone to operate for me. I would never have bothered if just for hobby use, but the mold ejection is the single best feature that improved results the most.
Very nicely done. Can you share the pressure you run your air rammer? I have felt for some time it would be worth building one for my casting business.
The mold squeeze and jolt section just runs direct from the compresser thats set around i think 85psi, the top cylinder is 50mm diameter and the bottom 65mm for the jolt bit. The mold spliter and blower are regulated.
Can't you use one of those air hammer or palm hammers you find at harbor freight? You could also use a few of the palm hammers attached under a flat surface to agitate the mold.
Thanks, yes i use the same size flask and matchplates for most of the parts i make, it can fill and ram a larger flask but the spliter only works for the flasks i make.
Hi I have a small project you can do or if you know someone who can do it for me. let me know. Its for a kitchen sink strainer. I have the mold. Its on 3" round by 1/4 thick
Hi, the machine is quite simple, just a steel frame welded together and simple pnematics all sorced from ebay. The hopper/feeder was second hand from a factory used for moving grains.
Super cool setup you got! And Very inspiring :) I do some hobby metal casting myself and would not fit such a setup yet; hope you will check out some of my content 🙏🏻
Thanks, its only realy practical for small scall production casting of multiple parts. Il check out more of your videos, il like the bottle lamp been thinking of making somthing simular for my workshop.
OK thank you and then your casting procedure is good for soft metals cause I don't think it would work for cast-iron cast iron is like a weird metal to work with it's finicky if you ever have a chance of making a video with the cast iron I would love to see it how it turns out thank you for replying and all the best luck to you
@@gilberttwaterfield6389 thanks, i can do cast iron with the same setup, and it gives a realy nice finish, but it realy burns out crucibles and destroys my oil sand in no time so i prefer to use bronze.
Yeah I know the crucible is the issue for all cast iron I think a 15 or 20 max pour after that you're a crucible it is very weak also it shrinks it to lose his height and a good crucible is not cheap
@@cringleengineering7688 a while back i read about some companies using vac bagging to pack the sand instead of pounding it. vac a sheet of plastic on the open sides of the flask. they'd talked about using it on the parting face too for a better finish, so, vac the pattern separately then vac it to the flask? it was a while back though, so i dunno, it was said it was used in production already... gotta be more than 20 years now. however, vaccing the patterns might mean you don't need to make a cloud of parting dust when you prep them and any benefits to the surface of the part would be gained.
1:58 RIP my ears... May they rest in peace. They had a good run... At least I don't have to suffer through Chris Isaak anymore when it's on the radio... The audio from this video went sort of like this... ua-cam.com/video/DrHMBletjXg/v-deo.html
Thanks, but i just dont think il have the time, i could do with making more for myself. I can share my patterns for them if you fancy making your own? There quite simple to assemble just need a good file, drill and tap but quite time consuming!
I first designed the machine so an unskilled old drunk man could operate it easily. It also obviously speeds up production and improves results and removes physical labour!??

Probably around £1k Including the compressor and all the parts and steel. Not including the hours spend designing and building it myself.

Seems like a lot of work for a home hobby setup. All that fancy stuff only benefits you if you’re doing volume.
Yes im obviously not making matchplates just for one offs 🤣
Hello, how did you make it?
Do you have any contact for further information inquiries?
Hi, the machine is quite simple, just a steel frame welded together and simple pnematics all sorced from ebay. The hopper/feeder was second hand from a factory used for moving grains.
Super cool setup you got! And Very inspiring :) I do some hobby metal casting myself and would not fit such a setup yet; hope you will check out some of my content 🙏🏻
Thanks, its only realy practical for small scall production casting of multiple parts. Il check out more of your videos, il like the bottle lamp been thinking of making somthing simular for my workshop.
Is this casting for Aluminum or for cast-iron
Bronze was used for this mold
OK thank you and then your casting procedure is good for soft metals cause I don't think it would work for cast-iron cast iron is like a weird metal to work with it's finicky if you ever have a chance of making a video with the cast iron I would love to see it how it turns out thank you for replying and all the best luck to you
@@gilberttwaterfield6389 thanks, i can do cast iron with the same setup, and it gives a realy nice finish, but it realy burns out crucibles and destroys my oil sand in no time so i prefer to use bronze.
Yeah I know the crucible is the issue for all cast iron I think a 15 or 20 max pour after that you're a crucible it is very weak also it shrinks it to lose his height and a good crucible is not cheap
such a drag..... yet you cope well.
No pouring basin. Olfoundryman would be disappointed.
hi sir why your sand is black?
Hi, the oil in the sand gets burnt around the casting and eventually goes black with soot/carbod. It is red in color when new.
@@cringleengineering7688 oh you are petrobond, thank you sir
next to add a vac bagger.
How would you use a vac bagger?
@@cringleengineering7688 a while back i read about some companies using vac bagging to pack the sand instead of pounding it. vac a sheet of plastic on the open sides of the flask. they'd talked about using it on the parting face too for a better finish, so, vac the pattern separately then vac it to the flask? it was a while back though, so i dunno, it was said it was used in production already... gotta be more than 20 years now.
however, vaccing the patterns might mean you don't need to make a cloud of parting dust when you prep them and any benefits to the surface of the part would be gained.
1:58 RIP my ears... May they rest in peace. They had a good run... At least I don't have to suffer through Chris Isaak anymore when it's on the radio... The audio from this video went sort of like this... ua-cam.com/video/DrHMBletjXg/v-deo.html
Sorry this is the first video i made, probably a bit of a shock if you just been watching myfordboy listening to the birds and wind in the trees.
@@cringleengineering7688 lol
Would you be willing to sell me a few of those lovely aluminum flasks?
Thanks, but i just dont think il have the time, i could do with making more for myself. I can share my patterns for them if you fancy making your own? There quite simple to assemble just need a good file, drill and tap but quite time consuming!
@@cringleengineering7688 Are they 3D printed patterns, or wood? I'd wager my shed is a bit far from yours? Cheers.
@@adirondackcarfoundry368 they are 3d printed patterns, i can share the stl files for them.
@@cringleengineering7688 cheers
@@cringleengineering7688 Hey! Could I also get those STL's please?
why just order the steel molds?
Cost more £ than i make

Really what's the point of this machine? To dispose sand and a hammer?
I first designed the machine so an unskilled old drunk man could operate it easily. It also obviously speeds up production and improves results and removes physical labour!??
