Abstract

Trata a invenção de processos eficientes e concretos para fabricação de moldagens, especialmente de lentes oftálmicas, tais como lentes de contato. Os processos compreendem uma série de aperfeiçoamentos, incluindo aperfeiçoamentos em áreas de condições para distribuição de prepolímero líquido aos moldes de lente, conjugação dos moldes macho e fêmea, moldes reutilizáveis, limpeza do molde, separação da lente dos moldes (desmoldagem) manuseio da lente, e inspeção em linha. Séries cíclicas de etapas de processamento são também apresentadas. Adicionalmente, uma ferramenta de moldagem aperfeiçoada é apresentada, sendo que a ferramenta de moldagem inclui um alojamento de molde macho e um alojamenuída uma pluralidade de metades de molde.
