Abstract
A column or other elongate molded part is molded using an elongate tubular mold having a closed end, an open end and a flexible sidewall. After the column or other molded part is formed, it is extracted from the mold by pulling the column or other molded part axially through the open end of the mold. The column may be extracted using an expandable plug or gripper that is inserted into the interior of the column or other molded part through the open end of the mold. The expandable plug or gripper is expanded to engage an inner surface of the elongate molded part.
