- In this video, Milo shows how he makes a prop wrench that looks exactly like a real metal casting. The casting is made using Smooth-Cast 325 resin and real metal powders.

to make the mold, Milo uses clay and alginate to split the model down its halfway point. Then, the first half of the silicone is poured. After this first half cures, the mold is flipped and the alginate and clay are removed. Then release is applied and the second half is poured.
After the original model is demolded, smooth-Cast 325 resin is mixed with So-Strong colorant and metal powder. This mixture is poured in the mold and allowed to cure, which creates a casting.
The casting is burnished with steel wool, and finished with a thin layer of shoe polish which is buffed.

Learn something new everyday Thank You!
Our pleasure!
Milo's vids are always so helpful and clear.
Glad you like them!
I would like to see an accurate medical grade skull in cold cast.
One of those skulls that has 3 parts.
The top that looks like a bowl, the base, and the bottom jaw.
I want to make one of my own! :D
Great idea! We will let the video team know.
Greetings Milo.
Great video. I've wanted to try the alginate technique to save time claying up molds. Will there be any issues with the alginate if the first pour of silicone needs to be pressurized?
Should be no issues there.
Hi, could it be as hard as aliminum?
How do your preserve the mold.
22:22 Is that a flux capacitor embedded in your oven(?) in the back left?
It is!
Neat!,BTW,your Flux Capacitor is running low on energy!
Hello thank u for the great video, would you please tell me how strong this is comparable to the original one, can we use it or is it just for decoration
This is a lightweight theatrical prop, not a functional wrench.
Can you use pressure casting techniques with the slower version of 325? Or will the metal filler not show up correctly? I would rather pressure cast the material if possible with this technique...
The metal powder may settle our when using a slower resin.
I've seen people coat the mold with the powder. It will embed on the surface of your cast. This is typically done using mica powder.
Did you dust the mold with the brass powder and have it mixed into the resin?
This was just mixed into the resin.
Which of smooth-on's metal powders is the brightest and shiniest when used in applications like this? Aluminum?

Do you have any products that would be strong enough for use in an actual wrench?
Probably smooth cast 385 at 85D
Our TASK 21 may also be a good material to test.
Something I’ve been thinking about - is if Silicone can only stick to Silicone, why not use two or more different version of Smooth on silicon for Mold making, ~ example- Rebound for details then say Mold star to make the rest of the Mold, or mix and match ~ the best of both products.
I do that a lot w rebound and moldstar/dragon skin. You just have to make certain that the silicones are compatible (e.g. platinum cure and tin cure do not play well together).
Pneumaddict yeah, it’s just something I’ve been thinking about for sometime, that I have noticed about the different versions smooth-on offers,
~ 💭 if you took that one and mixed it with that other one wouldn’t you get better results for you’re project (sort of thing)
Hi there!! I want to create an ornament mask , You think the foam it Will work? Or what other smooth on product I can use? I want it to be kinda strong and solid, thank You!!!
I think the Foam iT would be a good starting point to test. This is a good question for our tech support team, can you send them a ticket here? www.smooth-on.com/support/ticket/add/agree/ Thanks for watching!
@@smoothon sure! Thanks 🙏🏻🙏🏻🙏🏻
in all your videos i cant find a hollow object like a plastic water bottle moldmaking video. please make one would be super helpful
Do you have a specific project in mind? If so, this is a good question for our tech support team, can you send them a ticket here? www.smooth-on.com/support/ticket/add/agree/ Thanks for watching!
Can any of these be sent to be chrome?
It is possible, but you would have to check with a chrome plating service.
Can smoothcast 326 be cast into clay molds (sulfur free)?
It will bond to the clay. Any moisture in the clay may cause foaming of the resin.
@smooth-on Can a cold cast be polished to a high shine ?
It can be polished to a high luster, depending on the amount of powder you add. Because of the nature of metal powder, “chrome” type finishes aren’t really possible.
@@smoothon thank you for the quick reply. Would you be able to make a video showing the shiniest it can be by adding the metal powdes to the resin? Also can these be mixed with lead-free pewter?
I’m curious as to how clear it is without the powder
Aly, you can see the unpigmented material in the one minute video on this page: www.smooth-on.com/products/smooth-cast-325/
hello , i did the mistake to remove the props on the first mold and now it doesnt fit right...i get it about DO NOT REMOVE PODEL FROM MODEL, because now i got some space between my mold and props. What advice can you tell me to fix this before i pour the second mold ? thanks
You should apply release to the entire first mold half, even under where the model goes. That way, excess rubber that gets underneath can be removed and trimmed away.
I would like to see a Peterbilt 389 Cab 1:43 scale please
Great idea! We will let the video team know.
If it falls on the ground, does it break??
It would depend on the height, but urethane resin can be very impact resistant.
How do measure how much you need for your project?
We have calculators available on our site which can help you calculate this: www.smooth-on.com/support/calculators/
What materials are these strong materials that never break
These are urethane resins.
Thank you
How many times can you use this mold?
That depends on the texture of what you cast and how long you leave it to set inside. In both instances more means less.
Is this product as hard as the original one?
No, it is slightly more flexible.
Bro but can u use them like normal wranch tho ?
It wont be as durable as a metal wrench but it could work.
but how about density compare to the real metal can you test it please make a video I want to know about it..

is this food safe?
Mold Star 20T does not currently have a food safe certification, but all of our food safe products can be found here: www.smooth-on.com/applications/food-applications/
@@smoothon thanks they want custom salt & pepper pots
Copper powder? What type are you found in Arab countries?
Thanks for watching! A full distributor list can be found here: www.smooth-on.com/distributors/
@@smoothon Thank you
Could you give me how much the price for 1 kilo of copper powder and the price of polyester per kilo
All of these cold casting videos with the metal powder.... you never mention powdering the molds first, yet when you open the molds after casting, it's clear that has been done by the halo of color.
Also, you can't get that quality of metallic shine from just powder in the resin (which is why the molds should be powdered first).
Why do most of these videos omit the powdering of the molds, even when it has been done?
In this case, the residue is from an earlier test with powdering the mold. It didn't provide any benefit for this piece versus mixing the powder in, so that is the method we recommended for this tutorial.
