You may never have heard of Smooth-On, but you've seen our products at work. If you've ever been to the movies, admired a piece of sculpture, marveled at detailed architectural ornamentation or used a telephone; then you've encountered the handiwork of people who use Smooth-On rubbers, plastics, foams and other products to turn their ideas into 3-dimensional reality.

Estimating the amount of mold rubber and casting resin needed to successfully complete a mold and/or casting can be a difficult task. However, not having enough material or having too much material left over is not only frustrating, but costly.

This estimator calculates how much material you need based upon the mold box & model dimensions that you provide and the cubic inch per pound (or cubic centimeter per kilo) yield of the pour-on mold rubber and/or liquid resin.
