Latest Patents
Walter Trumbull holds a patent for an "Underwater pelletizer having sealed heat transfer tubes embedded in." This improved underwater pelletizer features sealed heat transfer tubes embedded within the extruder die. This design utilizes the heat of the molten polymer entering the extruder die by efficiently transferring that heat to the die plate and die face of the pelletizer. The invention also includes ceramic inserts and/or inserts of other insulating materials adjacent to the die plate to insulate the passages through which the molten polymer passes. This innovation inhibits the cooling of the polymer within the extruder die as it approaches the die plate. Additionally, water makeup is provided at the cutter blades of the pelletizer to prevent cavitation within the water housing, ensuring that pellets do not agglomerate.
