Molds warping.

[crabcreekind]

So yesterday i noticed that my molds were somewhat warped.. i use the plastic ones from woodnwhimsies. is this just soemthing that happens to these cheap molds when you use them alot? Is there any way to prevent warping? Also, i have been noticing that my casts were not straight but curved.. Is this from the mold or casting wrong?

that is typical of the plastic molds, this is generally what happens from the heat from the resin. Also your resin shrinks if you are using PR. So some of that is to be expected. I use PtownSubbie's molds(link is on my signature) for my Tru-Quarter blanks and my snakeskin casting and love them!
