Abstract

Procedimiento de elaboración de planchas de EVA (etilo-vinil-acetato) expansible y reticulable por inyección.Consiste en introducir en la tolva (2) de una máquina de inyección (1), los productos componentes de EVA (etileno-vinil-acetato) granceados o granulados, calentándolos hasta obtener una masa fundible que se inyecta seguidamente sobre una prensa vertical (5), la cual, mantiene a temperatura y presión determinada la matriz (4).La matriz (4) de dicha prensa vertical (5) permanece cerradaaproximadamente seis minutos y a continuación se abre para que la plancha inyectada (6) expanda.Con esta disposición se puede hacer variar la presión de inyección, para conseguir un óptimo acabado.
