Abstract: The invention relates to a mould and a method for the hot forming of a thermoplastic optical lens. The inventive mould consists of two dies (1, 2) which are mounted in a hollow shaft (3), so as to slide along the axis (6) thereof, and which comprise opposing forming surfaces (4, 5). The two dies (1, 2) and the shaft (3) are provided with intrinsic heat transfer means. The inventive method comprises the following steps, consisting in: placing a paraison or preform (P) of said thermoplastic material between the two dies (1, 2) and enclosing all of the latter inside the shaft (3); heating the dies (1, 2) and the shaft (3) to a forming temperature, using the intrinsic heat transfer means thereof (15, 16, 19, 20); bringing the dies (1, 2) closer together, in order to form the material by means of plastic deformation, until a pre-determined relative position is reached, said position corresponding to the desired thickness of the lens; cooling the dies (1, 2) and the shaft (3) to a stripping temperature, using the intrinsic heat transfer means thereof (15, 16, 19, 20); and extracting the finished lens (L) from the mould.

Abstract: The invention relates to a mould half-block comprising at least one mould cavity which is defined transversely by the useful surface of a shell. The aforementioned shell, which is provided with intrinsic, dual-purpose heat transfer means (heating and cooling), comprises: a base bearing all of the heat transfer means of the shell; and a removable insert which is mounted on the base and which bears said useful surface. The insert comprises no intrinsic heat transfer means and is thermally regulated solely by means of heat transfer with said base. Moreover, the insert, which is in the form of a cap, covers at least a head portion of the base and the heat transfer means of the base determine the head portion of the base that is covered by the insert.

Abstract: The invention relates to a method for the injection moulding of an optical element made from synthetic thermoplastic material. For each lens moulding cycle, the method comprises the following steps: the wall of the mould cavity is heated to a heating temperature which is greater than or equal to the moulding temperature of the material; the mould cavity is filled with said material; once filled, the pressure of the material thus introduced into the mould cavity is increased to a compaction pressure; the wall of the mould cavity is cooled to a cooling temperature in order to cool the moulded material to a stripping temperature which is lower than the melting temperature thereof, said cooling temperature being lower than the aforementioned stripping temperature. The filling of the mould cavity with said material is started before the heating temperature has been reached. When both the compaction pressure of said material and the heating temperature of the mould cavity wall have been reached, they are maintained for a given time.

Abstract: Disclosed are methods for preparing partially polarized optical articles. A polarizing element is used to cover at least a portion of the front surface of an optical article to form a polarizing zone and a non-polarizing zone on the optical article. The optical article is then tinted to produce a gradual color transition between the polarizing zone and non-polarizing zone of the optical article.
