Aluminum Mold Plates - 3-1/2" x 4-3/4"

These large 3-1/2 by 4-3/4 inch aluminum plates are designed for oversized jewelry pieces, belt buckles, or multiple-item mold frames. They provide a massive, stable platform that ensures even pressure is applied across the entire surface of a large vulcanizer platen. The thick aluminum builds a reliable thermal bridge that guarantees the center of the mold reaches the required temperature for a full cure. These plates are a professional necessity for manufacturers who work on large-scale silver or gold ornaments.
