Abstract

Un método para conformar una pluralidad de aplicadores de tampón que incluye los pasos de calentar una superficie de formación del elemento de formación; aplicar una porción de un primer aplicador de tampón a la superficie de formación; conformar la porción del primer aplicador de tampón; enfriar la superficie de formación; y remover la porción del primer aplicador de tampón de la superficie de formación; el elemento de formación tiene una conductividad térmica alta y una masa térmica baja; el paso de calentamiento de la superficie de formación del elemento de formación incluye calentarla a una temperatura mayor que el punto de suavizado del material que se puede deformar con calor de la porción del aplicador; el paso de enfriamiento de la superficie de formación del elemento de formación incluye enfriarlo a una temperatura menor que el punto de suavizado del material que se puede deformar con calor; el tiempo requerido para calentar y formar la porción del aplicador de tampón es menor que aproximadamente 90 segundos; estos pasos son repetidos para aplicadores de tampón subsiguientes; un aparato útil en un aplicador de tampón incluye un cuerpo de molde y pretenden proveer por lo menos una porción del aplicador de tampón al molde; el aplicador de tampón es formado por lo menos parcialmente de un material que puede deformarse con calor; el cuerpo de molde tiene un elemento de formación, una cavidad de fluido del elemento de formación, medios para aplicar calor al elemento de formación, y medios para proveer el fluido de enfriamiento a través de la cavidad del fluido del elemento de formación.
