Abstract

Una preforma de tereftalato de polipropileno (PET) (11) tiene un cuerpo cilíndrico (13) con tapa, una porcion superior roscada y un cuello (19) con boquilla es calentada para ablandar el PET. La preforma (11) se coloca en un molde partido (26) cuyas paredes (27, 29) se calientan a una temperatura entre 150 degree C y 177 degree C. Una varilla estiradora (35) se inserta a través de la parte superior de la preforma (11) axialmente hasta que la preforma está a la longitud del producto final (49). La preforma (11) es expandida usando aire del ambiente comprimido, y moldeada contra las paredes (27, 29) del molde (26). El aire es venteado, y se inyecta nitrogeno seco a una temperatura abajo de -50 degree C dentro de la preforma moldeada (47), para purgar y enfriar a la preforma moldeada (47) mientras que se mantiene la presion a menos de 520 kPag. La preforma moldeada (47) es mantenida contra el molde (26) durante un tiempo predeterminado, durante el cual las superficies externa e interna de la preforma moldeada (11) endurecen, y la preforma moldeada (47) se transforma en el producto final (49). El suministro de nitrogeno cesa y el producto final (49) se libera del molde (26).
