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.

You will not be able to make another master off your current mold its rooted,you will have to start from new,about the only thing you can do is gut the middle of the mold out on one side, fill it in with clay and place your master in,this will save alot of work without having to set up inlays and sprue holes etc.And yes you can make other molds of a master mold.
