Closed loop feedback press

The pressing of an article is achieved with a closed-loop feedback press. The closed-loop feedback press is effective to measure an amount of pressure applied and adjust the pressure to achieve a prescribed amount of compression on the article. Further, the press may leverage a closed-loop feedback system to maintain a consistent temperature of one or more platens. The press is able to adjust a pressure applied one or more times during a pressing operation to accelerate a temperature change in the pressed article while reducing the pressure applied as the temperature approaches a target temperature to limit unintentional deformation and bleeding of the pressed material of the article.
