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 Ejection 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) [/av_textblock] [/av_one_full]
