Here's a foam logo I made from a silicone mold. The mold was first coated with resin (1512) to add extra strength and to get perfect, bubble free detail. Foam was then poured to complete the piece.

  • @digitalmunky The amount of material needed is going to depend on the size of the piece and the rate of expansion on the foam. As for the time issue, that will depend on the speed of your machine. Call me and I can give you better, more specific advice.

  • @brickintheyard - Thanks for the reply. Actually, I already have been doing some manual rotocasting on my own, so I know the process. However, since I have not worked with the urethane foams, as of yet, I don't know the proportions needed to cast it in the thicknesses I'd need. Also, I don't have a clue as to the amount of time I would need to coat the entire mold so as to prevent voids in the final "shell". Any tips?

  • @digitalmunky Check out our video on rotational casting. That process can be done with EZ Flo 120 and some of the high density foams we carry.

    Maybe you can help me out... I've been looking for videos that show how hollow foam pumpkins are made, but have found none... Are they rotocast? Is the same self skinning foam, as used in many other applications, used to create them? Thanks in advance.

  • where do you buy resins etc?

  • This is SO beyond awesome! I am an artist and have so many things I want to reproduce rather than selling to originals...your videos are helping so much. I am off to buy my supplies to try out casting. I'm looking forward to it! :D
