1. Too high of temperatures and drying times will burn out the fragrance. In the absence of a desiccant dryer, the injection molding machine hopper may be used. Tray dryers may also be used. 2. The mold vent for the tool should be .002” to .003”. If this is not the case, mold temperatures could be elevated to help drive off volatiles thereby reducing surface blushing. (180°F – 220°F). 3. Most molding thermolators use hot water as their medium. In the case of elevated mold temperatures as shown above, oil thermolators should be used as they can achieve high temperatures of 220°F and higher without turning to steam.
