How To Mold & Cast An Alligator Snapping Turtle

Demold the original specimen once the rubber and mother mold have fully cured. The casting will be made with an outer shell of resin backfilled with an expanding urethane foam.

First, mix and pour the Smooth-Cast® 320 into the mold. Then rotate the mold by hand, allowing the Smooth-Cast® 320 to evenly coat the entire surface of the mold while curing.

Once the Smooth-Cast® 320 has cured (approximately 10 minutes), pour Foam-iT!® 5 expanding urethane foam into the cavity. This rigid foam expands 10 times its original volume, making castings lightweight and cost effective with great durability.
