    • A method for forming an embodiment of a fluid nozzle assembly includes removing two cores in opposed directions from a die set having a mold cavity configured to be a negative replica of the fluid nozzle assembly. The cavity includes the two cores, with one core configured to be a negative replica of: a fluid connector receiving bore; an inlet region of a nozzle; and a pass-through conduit, each in fluid communication with the fluid connector receiving bore. The other core is configured to be a negative replica of an outlet region of a nozzle in fluid communication with the inlet region. Removing the cores forms the nozzle assembly after molten polymeric material injected into the mold cavity has solidified. Removing leaves substantially no flash: at an area where the inlet region and the outlet region meet; and at an end region of the pass-through conduit distal to the receiving bore.
    • 用于形成流体喷嘴组件的实施例的方法包括从具有被配置为流体喷嘴组件的负副本的模具腔的模具组件沿相反的方向移除两个芯部。 所述空腔包括所述两个芯,其中一个芯被配置为负的副本:流体连接器接收孔; 喷嘴的入口区域; 以及每个与流体连接器接收孔流体连通的通过导管。 另一个芯被配置为与入口区域流体连通的喷嘴的出口区域的负的副本。 在注入模腔中的熔融聚合物材料已经固化之后,去除芯体形成喷嘴组件。 在入口区域和出口区域相交的区域,除去叶片基本上没有闪光: 并且在穿过导管的远离接收孔的端部区域处。
