    摘要: Injection molding units and methods of delivering a cooled molding material to portions of an injection molding unit are disclosed. An injection molding unit can comprise a barrel having a feed zone, a feeding portion configured for dispensing a molding material into the feed zone, and a cooling apparatus configured for cooling at least one of the feed zone or the feeding portion to a temperature that is selected to avoid or reduce bridging or obstruction of the molding material. The cooling apparatus can include a jacket configured to cover at least a portion of the feed zone or the feeding portion. The injection molding unit can further comprise an insulation shield. A method can comprise feeding the molding material into the feed zone and cooling the molding material prior to dispensing it into the feed zone or while it is in the feed zone.

    摘要: A pelletizer particularly useful for pelletizing water-dispersible melt-extrudate, among other materials, delivered from an extruder through a die positioned in communication with the interior of the pelletizer housing. The pelletizer includes a rotor disposed inside the housing and knives mounted around the periphery of the rotor. The knives pelletize the melt-extrudate as the rotor rotates. A fluid supply system selectively delivers a fluid, such as air, to the knives when the knives are at a selected location in the housing. The selected location is preferably just past the inlet and can extend in a circumferential direction around the housing in the area of the housing which is near the outlet. The circumferential extent can vary according to the configuration of the knives and the fluid supply system. The fluid supply system supplies fluid in a radially outward direction and tangentially along the cutting edge of the knives so as to sweep the pellets from the knives, as well as cool the knives, the pellets and the interior components of the pelletizer. The selective delivery of fluid sweeps the pellets off the knives as close to the outlet as possible. This prevents fouling, as well as avoids undesirable cooling of the knives in proximity to the die, which could lower the temperature and interrupt the flow of the extrudate.
