ABSTRACT:
A method to manufacture a blowout preventer seal including disposing at least one insert and at least one elastomeric material in a mold, heating the mold to a cure temperature, curing the at least one elastomeric material, measuring a temperature of the at least one elastomeric material during the curing, adjusting a cure time and the cure temperature based on the measured temperature of the elastomeric material, and removing the cured blowout preventer seal from the mold.
