Abstract

Un método para formar un artículo, método que comprende: (a) proporcionar un molde que tiene una primera parte de molde y una segunda parte de molde, primera y segunda partes de molde que tienen respectivas primera y segunda superficies formadoras de cavidad; (b) cerrar el molde definiendo de este modo una cavidad entre la primera y segunda superficies formadoras de cavidad; (c) inyectar una composición plástica fundida que comprende un polímero y un agente de soplado físico en la cavidad, donde durante o después del paso de inyección (c), la composición plástica inyectada en contacto con la primera y segunda superficies formadoras de cavidad se enfría para formar primera y segunda cubiertas sólidas respectivamente adyacentes a y en contacto con la primera y segunda superficies formadoras de cavidad, mediante lo cual en por lo menos una región de la cavidad está ubicada respectivamente por lo menos una porción de la composición plástica, porción en la cual por lo menos parte de la composición plástica entre la primera y segunda cubiertas sólidas permanece fundida, donde el grosor de la respectiva porción es constante dentro de una tolerancia de +/- 0,5%, preferentemente +/- 0,2%, en base a un grosor nominal de la respectiva porción; (d) abrir el molde antes de que la composición plástica fundida entre la primera y segunda cubiertas sólidas se haya solidificado en la por lo menos una porción, de manera de exponer la composición plástica fundida de la respectiva porción a una presión externa menor que la presión de inyección y permitir así que la composición plástica fundida entre la primera y segunda cubiertas sólidas de la respectiva porción se expanda mediante espumado para formar una espuma celular expandida como consecuencia de que la composición plástica fundida debajo de la primera cubierta sólida se expande hacia fuera alejándose de la segunda cubierta sólida que estira la primera cubierta sólida en la respectiva porción, donde el paso de apertura comprende extraer la primera parte de molde de manera que la primera cubierta sólida ya no esté en contacto con la primera superficie formadora de cavidad; y (e) enfriar la espuma celular expandida para hacer que la composición plástica fundida entre la primera y segunda cubiertas sólidas de la respectiva porción se solidifique y forme en el artículo por lo menos una primera parte que comprende una capa central de espuma celular entre la primera y segunda cubiertas sólidas, donde después del paso de enfriamiento (e) la longitud de la primera cubierta sólida en la respectiva porción se ha estirado, en comparación con la primera cubierta sólida presente antes del paso de apertura (d), en una relación de estiramiento que va de 0,5 hasta 3%, donde la relación de estiramiento es la relación del aumento en la longitud de la primera cubierta sólida después del paso de enfriamiento (e) en base a la longitud de la primera cubierta sólida antes del paso de apertura (d).
