Method for injection molding molded parts from thermoplastic and added fluid

摘要: A method for injection molding plastic molded parts from thermoplastic, comprises the following steps: production of a thermoplastic melt ( 1 ) through rotation plasticizing and screw 2 in preplasticizing cylinder 3 ); addition to fluid 4 by introducing into mixing up which has been added, rotational motion mixture cavity 8 an tool 5 ). In order make this suitable especially reliable reproducible large, foamed parts, invention is characterized that injected translational ), introduced at axial position 6 where channels 7 are situated least some time, pressure difference (delta p) between (P F (p s maintained essentially constant while being cylinder.
