Plasticizing Rotating of melt
Back pressure improves plasticizing
Dosing Deactivating, if the required volume is in front of the screw
Injection Axial movement of the screw forward à injection of melt
Switch over from “injection pressure” to “hold pressure” (compensation of PET- der PET-Shrinkage)
Cooling Deactivation of Holding Pressure = Start Cooling Nozzles close Melt for the next injection cycle is plasticized End of Cooling time is, when the preform wall temperature is <70 °C Ijection Mold opens Preforms are ejected by the ejection pins Mold closes Next injection molding can start Mold structure / assembly Mold Cycle Time (Single Step) – Preform 26,5g (Standard Plasticizing: 12 g/sec)
