Here at Resin Heroes, we find that one of our silicon molds is good for about 20 castings before they start to fail and fall apart. You can see this happen in the photo below from a recent casting or Robin, the Boy Wonder. Here, bits of the mold have been left behind in Robin’s left eye and in his hair. Once we remove the excess molding this particular cast of Robin is fine, but it means that the master mold for Robin is effectively, for lack of a better term, dead.
Worry not since we can make a brand new mold for Robin from Sean’s original Robin sculpture.
