Injection Molding Know-How: Drying Tips: A Dozen

2009-12-1 · Once dry, most resins will pick up moisture in 15 to 30 min. Therefore, do not convey from a central hopper to the machine, or leave it in the machines hopper, without a blanket of dry air. Note where the dry air enters the hopper and meets the resin. Hot air will only travel upward. Do not believe the arrows on dryer drawings.
