Start Up 2
Vol. 21 #3, Dec. 1994
On cold start up, turn on die and adapter heaters 30 minutes to 1 hour before turning on barrel heaters so they both reach start up temperature at the same time. This helps prevent degradation of the resin in the barrel while waiting for the die to come to temperature.
Ask your suppliers for start up, shutdown, and purge procedures for your resins and extruders. Prepare and follow written procedures for each extruder based on this input.
