Mold-alignment paper - Sensor Products Inc.
Mold-Align® paper changes color when subjected to pressure. Its primary use is between platens on mold parting lines. Mold halves are clamped together with minimal force, then the paper is removed to reveal voids, high spots, and other problems that can affect product quality.
Mold-Align® comes on a roll and can be cut to the required size. Used paper may be archived for future comparison.
