Abstract
PRESSE A MOULER PAR COMPRESSION. DANS L'UNE 5 DES MOITIES DU MOULE 4-5 UNE PARTIE DU FOND DE L'EMPREINTE DE MOULAGE EST CONSTITUEE PAR LA FACE LIBRE D'UN PISTON 6 MOBILE A JEU TRES REDUIT DANS UN ALESAGE DE LADITE MOITIE, TANDIS QUE LES DEUX MOITIES 4, 5 S'APPLIQUENT L'UNE CONTRE L'AUTRE SANS SE COMPENETRER. LORS DU REMPLISSAGE DU MOULE 6, IL EST ABAISSE POUR QUE LA FERMETURE COMPLETE PUISSE S'EFFECTUER SANS CONTRE-PRESSION NOTABLE, PUIS ON LE RAMENE A SA POSITION HAUTE EN COMPRIMANT AINSI LA MATIERE QUI REMPLIT ALORS TOTALEMENT L'EMPREINTE. MOULAGE DES THERMO-DURCISSABLES.
