mccrary53 Posted June 6, 2007 Report Share Posted June 6, 2007 hi guys i want to start pousring all my soft plastics and belive that it could be a sound investment but i need to know can i expect to make an rtv or plaster mold of all of the baits i want to pour and expect to get quality results ie. fine detail or would i have to buy aluminum molds to get the same quality that i get from zoom or reaction innovations. and is there a cheap way to make molds with great detail.

dampeoples Posted June 6, 2007 Report Share Posted June 6, 2007 There's no shortcut, or there would be no aluminum molds! Quote Link to comment Share on other sites More sharing options...
Travis Posted June 6, 2007 Report Share Posted June 6, 2007 Fine detail is going to be hard to do. I however believe that with careful preperation and excellent masters that you can come very close making your own molds with several mediums. RTV hands down will be the easiest to pick up detai. If you take your time and have good masters and prep the pour box properly and use a vacuum to degas you can get some very good quality molds. I have molds made from bondo and durhams that have picked up great detail also. Now aluminum much easier and better results but I have durham's rock puddy molds of some lures that you would be hard pressed to pick out the hanpours versus the originals without squeezing them.

mccrary53 Posted June 7, 2007 Author Report Share Posted June 7, 2007 travis i think i will try to make some molds out of rtv and give it a shot but what do you mean degas with a vaccum is that where you make a box for your shop vac i also have been looking over the tutorials on making a mold and i think i have a decent idea how to prepare it but what are vent holes and do i need them in my mold thanks so much for the help you guys are awesome Quote Link to comment Share on other sites More sharing options...
whteglve Posted June 7, 2007 Report Share Posted June 7, 2007 Please note that I have NO soft plastic pouring experience, BUT I do have mold making experience. I've made molds for miniatures for a while. I think that if you use GI1000 and your plastic doesn't get hotter than 400 degrees (if I remember correctly) you shouldn't have a problem, or you could go with the high temp stuff for more cost. Plus it will pick up more detail than you'll ever need. I've had models of knights that were 1 inch tall and GI1000 will pick up the detail of the hair sculpted on their heads. Also I don't put mine in a vacuum. I set the pour box on the bench and pour from about 18-24 inches and since with GI1000 you can get an almost hair thin stream from the pouring vessle it haven't had any problems with air bubbles.
