Method for applying a surfactant to mold surfaces

摘要

A method of and apparatus for employing a surfactant which is provided in order to assist in the release from each other of mold components of a multipart mold employed in the molding of polymeric articles; for instance, such as a hydrophilic contact lens, upon completion of the molding process for the polymeric articles. The surfactant is applied in the form of a film or coating on surface portions of one of the mold components in order to facilitate the disengagement between the mold components during demolding, and the removal of excess polymeric molding material adhesively deposited on surfaces thereon.
