Patent

CA 2723781

An injection molding apparatus and method of use are provided whereby a net- molded optical article can be produced. Edge wave deviations are reduced by controlling the cooling profile of the resin. The apparatus can be configured to include at least one heat control element disposed adjacent to an edge of the mold cavity. After plasticized resin has been injected into the mold cavity, the edge of the mold cavity can be thermally regulated relative to the center of the cavity.

Linvention concerne un appareil de moulage par injection et un procédé dutilisation grâce auxquels un objet optique moulé peut être produit. Les déviations donde de périphérie sont réduites par la régulation du profil de refroidissement de la résine. Lappareil peut être configuré pour inclure au moins un élément de régulation thermique disposé de façon adjacente à une périphérie de la cavité du moule. Après linjection de résine plastifiée dans la cavité du moule, la périphérie de la cavité du moule peut être régulée en température par rapport au centre de la cavité.
