A method and apparatus for molding thermosetting and thermoplastic materials, particularly components of brassiere cups, enabling precise molding with a high degree of flexibility and control in the molding conditions of temperature, pressure and molding time. Two modes of molding are disclosed; a first mode in which the material is first clamped to the mold prior to conforming the medial portion of the mold to the mold blank; and a second mode in which the material is accommodated in the mold blank followed by clamping of the margins of the material.
