Purging pellet grade selection guideline

Purging method recommendations: Using both automatic purge and short purge jointly is recommended.

Short purge is a method for repeating “less measurement/weighning” and “high-speed injection”.
  • In case of our 80-ton molding machine, for an example, cleaning is done by setting the measurement to 15 mm, and the speed increased from normal 100 msec to 120~150 msec.
  • Rotation speed and temperature are set the same as those of molding conditions for the prior material.
  • This method is effective for discharging ecomaru by subsequent material as well. Please take a look at here for cleaning method recommendations .
