This is the first video I’ve watched from Green and Machines. I had to subscribe. Not only did he thoroughly show a breakthrough idea for molders, but his personality made the video very fun to watch.
You're supposed to release the parts right after pouring while the aluminum is hot. Otherwise, it shrinks to the mold and not only is harder to get off, but you create shrink tearing and shrink stresses in the part. You should also be using a release agent. The mold should be hot before pouring.
@@silverseven5283 You need to do your own research into this and there are many websites dedicated to this topic. There are many differing types of release agents available for this type of die casting. You simply need to study and research on your own. 🤔🧐👌💯
Nice to see the failures along with the successes. I'll not repeat the steps missed, but this does give me the idea of what I need to do for my own project. Thanks and good job!
Excellent video, interesting project. This is a short presentation, but well explained and detailled. Improvements, of course, would be necessary but you have here a good start. It gave me inspiration for some of my futur projects. Thanks.
Dude I appreciate your hard work your machine is quite good for fast production you just to put a electrical or machenical moving padta for ejection and you must apply die coat or some realising agents on the surface of your Mold for a better and hazel free ejection thank you and after all your machine is very good
Recommend you drill through a small hole for air to leak out of dowel holes whenever possible. As long as it does in effect anything else. Makes disassembly easier for tight tolerances.
you need to coat your moul with diecoat..., also donot let the aluminium cool in the moul, it will contract and bind.. you must also heat the mould up before casting.. . mould should be hot when aluminium goes in.. if these two things are done it will cast smoothly and fall free from the die.. you cast it then without less than a minute you crack the mould and take the aluminium out.
@@greensnmachines can't remember the name of it large mold manufacturers buy it in spray cans and by the pail . We used it in school borox something like that I watched it in a video . I will see if I can find a name .
@@greensnmachines I am going to try porslin coating my steal crucible to see if that makes it last longer might work for molds .try on a simple cheep mold if you are going to try it . My crucible is 2 foot wide and 2 foot high .i an setting up to do tons of aluminum and making plate i beam angle c Chanel. Nice program catch u later .
Brother it seems to me that your low knowledge about die casting is costing you alot. Please read about die casting releasing agents like graphite powder mixed with sodium silicate. Its impossible to do it the way you do

how awesome is that!!!! ill see u in 11 days! very impressed. now you have to find a use for soap dishes!
Thanks Emma, see you there!
Super cool!

Great job, thanks for your entry.
Great attitude and humour. Love it.

Interesting and very helpful. I'm new to home die casting. What kind of releasing agent(s) would you like to suggest if i may ask??

Good luck with the competition.
Doing great waiting for yr next!

Sweet. Try to get it out in 60 seconds and it will be much easier
nice work
I was f.. looking for this for years.
You're god
Süperrrrr Art
Thanks for convincing me to stick to sand casting. LOL.

Really no need for the thick heavy metal as well.
That was cool brother. Use a hydraulic bottle jack to push the pins.
Well done but I must say you must go through a lot of soap dishes to want to make something like this:)
Good luck in the competition.
Cheers
Peter
That's a nice setup
I suppose you could set up interchangeable moulds for whatever you want to cast
Yeah, I've been thinking of what to make a mold for next.
Prenca de moldagem muito boa
❤
Thanks for the insight on how these die molds are made. Could the screw be automated with say a stepper motor to eject the finished piece?
I was thinking either an impact driver or bottle jack
Debes pintar los moldes con una pintura especial, así llenará más fácil y también extraerá igual!!!
You gotta heat your mold and release it right after pouring. The metal is also much thicker than it needs to be.
Tienes que extraerlo cuando esta calientito, para esa pieza con 5 minutos es suficiente !
Great job I am from India and I want to learn about die-cast
What type of metal is that cast iron or MS.for metal DIE casting cast iron is best.i from India we use cast iron die's for it.
When are you going into production?, I want to buy a soapdish. Baddabing, Subscribed.
How much does a mold like this cost
Please I need a mold, how much is it
اريد ان اسألك عن امر
ماذا لو صنعنا القالب بالجبس ثم صنعنا نسخه اصليه له عن طريق السباكه بالامر ما رأيك بهذا
You might try to put a couple release pins on the sprue .
Yes, that is one of the improvements I've been considering
Você pode usar tinta de grafite em seu molde.
what kind of metal structures are you using? i mean is it martensite or..etc
I would have to guess everything is ferrite for the most part, easily machinable
Hello . Would a permanent mold be suitable for copper casting? very small castings
Not sure, I usually only hear of it used for aluminum or zinc most of the time. Copper might be too hot and erode the mold prematurely.
a question or dozen. did you use "mold wash"? what brand? poppy
No, is that a release agent or something?
spray the mold with mold release or black it with an oxy torch or choked propane torch and the part wont stick
mold wash puts a coating on the mold (metal of course) the aluminum dont stick to the coat.
do you have any draft milled on the sides?
yes, 3° draft
I think You need air impact to turn the press turner
It would certainly help!
what is the material of the mold? iron or steel?
You can read more about how the mold was built on our blog here:
www.greensandmachines.com/2013/05/building-die-casting-mold.html
Hey. What was the draft angle you used?
3°
I think you use hydraulic instead of bolt Mechanism
in production, washing is a periodic task . brown ochor MIGHT help, if woy dont use real moldwash. poppy
Hello, this is a mold for plastic? and my other question is why don't you use drill bits to make the holes?
Aluminum by the looks of it.
I want to make something . How much I charge for making the mold . I know furnace n melting alumunium I only want the mold

Hi
Spray molds with mold spray every 4 or 5 uses .
Have you got a good source for some?
@@greensnmachines can't remember the name of it large mold manufacturers buy it in spray cans and by the pail . We used it in school borox something like that I watched it in a video . I will see if I can find a name .
@@greensnmachines it is called boron nitrate high temperature spray .
