Abstract

Proceso de formación de un artículo hueco por deformación de una plancha de material termoplástico, particularmente material de poliofelina, posicionando una plancha sólida calentada de material termoplástico sobre un molde, moviendo dicha plancha con relación a un elemento deformador de la plancha, de tal modo que la plancha sufra una deformación inicial, aplicando una diferencia de presión entre la cara interior y la cara exterior de la plancha por medio de un fluido gaseoso, de tal modo que la plancha se hinche y sea presionada contra la pared interior del molde, en el que se deforma una plancha de material termoplástico, calentada a una temperatura de aproximadamente 10 a 40º C, por debajo de su temperatura de fusión cristalina.
