Abstract

"APARELHO DE MOLDAGEM E MéTODO DE MOLDAGEM" O aparelho (10) descrito compreende um tambor (12) no qual existe um pistão (42) em uma haste (36). A haste pode ser movida axialmente e é circundada por uma rosca de avanço (14). Existe uma válvula de fechamento (62) no tambor. A rosca de avanço é usada para encher uma cavidade de detenção (C) entre o pistão e a válvula. A válvula é então aberta e o pistão força a carga da cavidade (C) para dentro da cavidade de moldagem (30).
