Molds with this material are made to last, however, molds will degrade over time/usage. There are many factors that determine how fast a mold degrades. Here are several things to take into consideration: - Heat wears molds out. Using a torch on molds will damage them. Please stay away from using heat on molds! - Slow curing resins place greater stress on molds. - Mold releases extend a mold's life. - Pouring thicker than the resin's recommended depth may damage molds due to heat from the exothermic reaction. - Bubbles formed on the surface of a mold (especially 3D molds) can scrape the molds during the demolding process. Please make sure that there are no bubbles on mold's surface. - Overstretching molds might cause permanent damage to them. ...and many more. Even though these are high quality molds, misuse can damage or degrade them.
