Abstract

La invención se refiere a un método para producir piezas de plástico termoformadas a partir de tereftalato de polietileno amorfo que esté libre de agentes nucleantes. A fin de permitir la producción de piezas de plástico de un solo tipo, reciclables, transparentes y con tiempos de ciclo económicos y un bajo consumo de energía, que sean adecuadas para su uso en microondas, según la invención: en un paso de suministro, en primer lugar, se suministra un producto semiacabado (1) con una anchura de producto semiacabado predefinida, en una dirección de la máquina (MD) que discurre en paralelo con la dirección longitudinal del producto semiacabado, a una sección de procesamiento (3) de un dispositivo de termoformado que comprende un molde de termoformado; y en al menos una etapa de calentamiento se calienta a continuación en la misma a una temperatura de embutición de 90-180 C; y en al menos un paso de embutición se embute activamente, en una dirección de la máquina (MD), sobre la base de la temperatura de embutición ajustada a un grado de embutición de 1,2-5,0, en donde la al menos un paso de calentamiento tiene lugar al mismo tiempo que el al menos un paso de embutición o temporalmente antes del mismo; y, después de lo cual, en un paso de conformación, el producto semiacabado (1) extraído en la sección de procesamiento (3) se retira del molde con la ayuda del molde de termoconformado enfriado y, en el proceso, se enfría a una temperatura de al menos 30 C por debajo de la temperatura de transición vítrea del tereftalato de polietileno utilizado.
