Abstract
"PROCEDIMENTO DE RESFRIAMENTO E CONTRAPRESSãO PARA A PRODUçãO POR INJEçãO DE PEçAS DE PLáSTICO". Um procedimento de refrigeração para a fabricação de peças de plástico por injeção, que utiliza um gás sob pressão que é alojado em uma cavidade provida de duas partes de molde (1, 2) durante ao menos a fase de resfriamento. O gás frio, e sua aplicação, cobre tanto a parte revestida quanto a parte não revestida.
