摘要： A method of manufacturing an extruded part having an exterior shell and a core foam material. The method includes extruding the exterior shell from an extrusion die, and reaction injection molding the core foam material within an interior of the exterior shell using a distribution block having a plurality of orifices configured to inject the core foam material within the interior of the exterior shell. The orifices are configured to evenly distribute the core foam material throughout the interior of the exterior shell. the method can be used to form an exterior shell having a plurality of internal chambers, where the orifices of the distribution block are configured to inject core foam material within the plurality of internal chambers.

摘要： A method for continuously and cost-effectively producing expanded thermoformable honeycomb materials comprising the steps of: providing raw thermoformable thermoplastic material (such as flakes or pellets) into an extruder; heating the material in the extruder; extruding the continuous sheet material to a suitable gauge and width; trimming the extruded material while it is still hot to desired widths; conveying this hot thermoformable, continuous sheet into a preheat/heating section comprised of either hot forming rolls or belts; heating the thermoformable continuous sheet on forming rolls or between continuous forming belts that have specific geometries machined on the surfaces; adhering the continuous sheet on the forming surfaces by hot tack adhesion; expanding the continuous sheet into expanded honeycomb by separating the forming surfaces so as to effect an expansion of the cross-section of the thermoformable continuous sheet material; transferring the expanded honeycomb through an array of cooling rolls or belts thereby cooling the expanded honeycomb thereby maintaining its integrity and facilitating its release from the exit of the cooling region.

摘要： The present invention relates to a system and a method for cooling extruded and molded materials. The present invention is especially useful to thoroughly cool an extrudate by directing a cooling fluid toward a surface of the extrudate (e.g., an interior surface that defines a hollow portion of an extrudate). Hollows may be created in order to reduce material, weight, and/or processing time. A cooling fluid is diverted toward the surface of the extrudate so as to cool the material and assist in solidification. A baffle may serve to divert the cooling fluid in the desired direction. In another example, the extrudate may be partially or totally immersed in a liquid cryogenic fluid. Increases in production line throughput may result by rapidly cooling the molded material. In addition, the more efficient cooling may be achieved with a lesser amount of the cooling fluid, and the velocity and temperature of the cooling fluid may be reduced. Other uses for the present invention include injection molding, compression molding, gas assist molding, and co-extrusion.
摘要翻译：本发明涉及用于冷却挤压成型材料的系统和方法。本发明特别可用于通过将冷却流体引向挤出物的表面（例如，限定挤出物的中空部分的内表面）来彻底冷却挤出物。可以创建空腔以减少材料，重量和/或处理时间。冷却流体朝向挤出物的表面转移，以冷却材料并帮助固化。挡板可以用于在所需方向上转移冷却流体。在另一个实例中，挤出物可以部分或完全浸入液体低温流体中。通过快速冷却模制材料可能导致生产线生产量的增加。此外，可以用较少量的冷却流体实现更有效的冷却，并且可以降低冷却流体的速度和温度。本发明的其它用途包括注射成型，压缩成型，气体辅助成型和共挤出。
