摘要

Injection molding machine comprising an extruder (1) and a mold (8) comprises an initiator supply port downstream of the extruder screw (3) and a mixing device that is mounted in the feed channel (7) of the mold and positioned in the closing plane of the mold. An independent claim is also included for producing an injection molded part by plasticating a thermoplastic material in an extruder, injecting the material through a nozzle (4) into the mold and removing the product from the mold, where the material is mixed with an initiator in the injection path between the nozzle and the mold cavity, the mixture is injected into the mold, and initiator-free material is then injected in a volume corresponding to the volume of the injection parth.
