- Moldmaking and casting tutorial - In this video, we show how Mold Star™ 30 silicone is used to create a 2 part mold. TASK™ 4 urethane resin is poured into the mold to create a thin walled casting of a model train car.
Mold Star™ liquid rubbers from Smooth-On are easy to use platinum silicones which are mixed 1A:1B by volume (no weighing scale necessary). Mold Star™ silicones feature relatively low viscosities and vacuum degassing is not required for most applications. Mold Star™ 30 is a harder material, with a 30A Shore hardness.
TASK™ 4 is a unique liquid polyurethane casting resin that is very strong when cast in Ultra-Thin sections ranging from 0.03” to 0.50”(0.075cm to 1.27cm). TASK™ 4 has a very low mixed viscosity, ensuring flawless pick-up of even the finest detail. Cured plastic exhibits very low shrinkage which is why this plastic has become a favorite of prototyping and design professionals throughout the world. Pot life is 20 minutes and cure time is 16 hours at 73°F/23°C.

Liked so much!
I guess you could pull it out early, while it is still soft, and twist it , press it in, warp the panels, disfigure it, simulating a car that was wrecked. Pretty neat. Great video.
Great idea!
I'd like to try it on a 3' section of flex track. Cast a couple of sections to simulate yard track, with dips, bumps, uneven rail zigzag, like some of the yards had in the 1980's, Like Rock Island and ICG had when standing derailments were common. I know it wouldn't be powered, so placed damaged cars or the mow wreck train cars on it.
you can also buy a die cast car and hit it with a hammer. same results!
How did you mold those steps and supports on the ends of the car? It seems that you won’t be able to remove those from the mold.
a tip: watch series at Flixzone. Been using them for watching a lot of movies these days.
@Harlan Wilder Definitely, been watching on Flixzone for months myself :)
Thanks for posting this! I think i'll be using this method a lot!
Thanks for watching!
Super helpful video
Wonder how difficult it would be to replicate tyco’ sir Revell’s operating coal hoppers. May need to get some.
Could you also 3D print your model, mold it, and then cast your mold?
Great video! I have a plastic box I need to mold with a weird geometry, I'll try to describe it in detail so someone can tell me if this method could be used.
The object is a cube, around 3cmX3cmX3cm. Said cube is hollow and its bottom face is a separate part fastened by screws. The top face of this cube has a circular opening in its center (about 1cm in diameter) and each side has slots that go from the very bottom to about the middle point of the sides.
Can I use this method to create a mold for it? In a video I saw of the casting for a scale model car's body the inside part of the master was completely filled with clay, should I do this instead?
I like the premiss but the problem with it being so light is that you would have to weigh it down. Personally I would like to try and do live coal loads when I make my layout soon.
And how can the trolley (wheels) be made? Can they always be created with a silicone casting? Thank
Time to make a million troublesome trucks.
Lol
When you mix the mold components you did not vacuum the material? Is that not required due to size or the material itself?
I would like to try this with n scale oar jennies and mold 4 in one mold...
Great video also!
Vacuuming is not necessary with the Mold Star silicone and resin shown.
I have a heap of Atlas-RR 30' shorty beer can tank car chassis' that need tank's for, your method looks great and I can't wait to get started to mold them, thank you for posting your video.
Thanks for watching! Good luck on your project!
Can you color this casting material with paints such as Floquil Solvent Paint or Testors Enamel Paints? This would allow casting in the exact appropriate color, in theory, requiring no top coat of paint.
It is best to use a pigment or colorant designed specifically for urethanes so that no chemical reaction occurs
What was the total cost of everything to make the car?
I looked up the materials you describe here in the video, and, it doesn't list "MOLD STAR", in your catalog. I would like to use this method to make 5 bay ortner cars. I refuse to spend $45 to $65 for one car. I'll make my own first.
Thanks!!!
Taz...
ho scale granite rock must have
thanks!
Thanks for watching!
do you have a catalog?
We do! Use this form to request one - www.reynoldsam.com/contact/catalog/
thanks again!
Great video. what is the name of this song?
Does it work for passengers car's?
Perhaps
How can you cast a train car if it has windows?
You can use tape on the inside to keep the material from flowing through.
Thank you!
Using the method shown in the video, you actually wouldn't need to tape anything. The small steps and framing at the bottom of the hopper are effectively windows, they have material in a frame with a hole in the middle. If you follow the same steps used here you should be fine. The glass of course would be modeled by another material. I use any hard thin clear plastic. Just be sure not to use any harsh glues like super glue when putting the windows in because they WILL fog up your windows. So unless you're looking for that "frosted" look, just use a dab of elmers glue and let it dry thoroughly.
@@anfasharchive3244 You could also use their "Crystal Clear" line of resin for new windows.

Use this method so you cant waste your mone
