Making a Block Mold of a Four Legged Animal

Overview

One of the more common mold making application questions that we receive is how to mold and cast a four legged animal, such as a horse with different leg positions and flowing tail.  The key to being successful and subsequently getting a perfect reproduction is to know where to properly place air vents and also where to make your extraction cut line.

Mold Max® 30 is the mold rubber featured for this demonstration. The mold will be a one piece cut block mold with air vents placed at strategic points to minimize air entrapment during casting. Smooth-Cast® 300 casting resin is then used to make an exact duplicate of the original model.
