Plastic injection molding temperature


Plastic injection molding temperature is the very important paramter during the plastic injection molding processing, the plastic injection molding temperature including:

  • plastic injection molding molds temperature
  • plastic injection molding molds hot runner system temperature
  • plastic injection molding machine screw and barrel temperature
  • plastic injection nozzle temperature

Below has listed out the plastic injection molding temperature of mold and machines, because for the hot runner system their temperature should be similar to the injection # 1 and injection #2. Also the nozzle temperature should be similar as injection #1.
