Abstract: A molded article includes a rotationally-molded body of polymer material, formed in a mold, with an elongate reinforcing member, having an end, substantially encased within the body of polymer material during molding thereof. A slip zone, defining a void in the body of polymer material, is formed around the end of the reinforcing member, such that post-molding shrinkage of the polymer material imposes substantially no stress on the end of the reinforcing member.

Abstract: A molded article includes a rotationally-molded body of polymer material, and a reinforcing member substantially encased within and in direct contact with the polymer material. Both the polymer material and the reinforcing member have their own unique post-molding shrinkage characteristics. A slip zone, defining a void in the body of polymer material, is formed around the end of the reinforcing member, such that post-molding shrinkage of the polymer material imposes substantially no stress on the end of the reinforcing member. The reinforcing member has a surface coating that substantially eliminates adhesion with the polymer material, so as to enable displacement of the reinforcing member with respect to contacting polymer material, and thereby reduce post-molding deformation of the molded article.

Abstract translation: 模制品包括聚合物材料的旋转模塑体，以及基本上被包裹在聚合物材料内并与聚合物材料直接接触的加强构件。 聚合物材料和加强构件都具有它们自己独特的后成型收缩特性。 在加强构件的端部周围形成了在聚合物材料体中限定空隙的滑动区域，使得聚合物材料的后成型收缩基本上在加强构件的端部上施加应力。 加强构件具有基本上消除与聚合物材料的粘附的表面涂层，从而能够使加强构件相对于聚合物接触的位移，从而减少模制品的模制后变形。

Abstract: A decorative post includes an elongated outer polymer shell having at least one longitudinal groove extending a majority of a length of the elongated shell sized and shaped to hold a decorative fence panel. The decorative fence post also includes an elongated reinforcing member disposed in the outer polymer shell, and substantially extending a length of the fence post. A foam filler is disposed inside the outer polymer shell between the shell and the reinforcement member. An aperture is disposed in the outer polymer shell near an end of the reinforcing member, and a void extends from the aperture into the foam filler adjacent to and exposing an end of the reinforcing member. The void defines a slip zone at the end of the reinforcing member into which the reinforcing member extends as the outer shell shrinks longitudinally during post mold cooling.

Abstract translation: 装饰柱包括细长的外部聚合物壳体，其具有至少一个纵向凹槽，所述至少一个纵向凹槽延伸出细长壳体的一部分长度的大部分，其尺寸和形状被设计成保持装饰栅栏面板。 装饰栅栏柱还包括设置在外聚合物壳体中的细长的加强构件，并且基本上延伸一段长度的栅栏柱。 泡沫填料设置在壳体和加强构件之间的外部聚合物壳体的内部。 在外部聚合物壳体中的孔附近设置在加强构件的端部处，并且空隙从孔进入邻近并暴露加强构件的端部的泡沫填料。 空隙在加强构件的端部处限定滑动区域，当后模具冷却期间外壳在纵向收缩时，加强构件延伸到该滑动区域中。
