I have a two piece Injection mold for a swimbait. I am trying to reproduce the master mold. At the current time I am using dow chorine RTV to make imprint plug of the master mold. I am having some issues with the reproduction mold, faces are'nt matching up and shrinkage when I pour procast 20 into the imprint plug. Any suggestions with a different proccess in reproducing a mold off of a master mold. Thanks.
