Abstract

La presente invención se refiere a un método para moldear premoldes laminados del tipo que incluye una capa de barrera interior el método comprende los pasos para proveer un molde por inyección para un premolde en el que el molde por inyección un núcleo en el que una cavidad que rodea el núcleo provee suministros separados de cuando menos una resina termoplástica fusible y un material de barrera fluible, que se inyecta a aquel extremo de la cavidad del molde, que determina una parte inferior del premolde, una cantidad limitada de la resina termoplástica con las porciones de superficie de la cantidad limitada de resina termoplástica que se enfría debido al contacto con el molde y con el núcleo de tunel de la resina termoplástica entre las capas solidificadas que inyectan una cantidad limitada del material de barrera a la cavidad del molde detrás de la cantidad limitada de resina termoplástica con el material de barrera que impulsa la resina termoplástica más allá en la cavidad con el material de barrera que tiene un flujo de tunel entre las capas solidificadas de resina termoplástica con las prociones de superficie del material de barrera en contacto con las capas solidificadas de resina termoplástica que también enfrían y moldean las segundas capas solidificadas y la inyección después de otra resina termoplástica fluible a la cavidad del molde detrás del material de barrera suficiente para completar el llenado de la cavidad del molde con otra resina termoplástica fluible, que impulsa las cantidades limitadas de la resina termoplástica y el material de barrera para fluir hacia el otro extremo de la cavidad del molde y pemitir que todo el material inyectado se solidifique.
