Abstract
Methods and apparatus for demolding a polymeric material from a mold are disclosed, the methods comprising the steps of placing a material within a mold, closing the mold, molding the material located within the mold, and opening the mold. The mold includes a demolding tool having a material-engaging portion that is in fluid communication with the mold portion, the demolding tool being reversibly disengagable from the first mold member. The demolding tool is disengagable from a resting position within the first mold member to translate from the first mold member the molded polymeric material associated with the material-engaging portion, thereby separating a portion of the molded polymeric material from the mold cavity. In particular embodiments, the material-engaging portion is a cavity. In other embodiments, the material-engaging portion is associated with one or more longitudinal members extending across a portion of the first mold member.
