    摘要： Methods and systems for co-extruding multiple polymeric material flow streams into a mold cavity to produce a molded plastic article having an injection-formed aperture in gate region of the article are disclosed herein. A method includes providing a valve pin having a distal portion with a first diameter and a mid-portion with a second diameter smaller than the first diameter and providing a mold defining a cavity corresponding to a shape of a resulting molded plastic article. The mold has a recess aligned with a gate region of the mold, extending into the mold and configured to receive the distal portion of the valve pin when the distal portion of the valve pin extends beyond the gate region. The method includes advancing the distal portion of the valve pin into the recess until the mid-portion of the valve pin at least partially extends into the gate region, thereby establishing a flow path for a combined polymeric stream into the cavity at the gate region for forming a molded plastic article having at least one layer of a first polymeric material and at least one layer of a second polymeric material. The method also includes withdrawing the mid-portion of the valve pin from the gate region, thereby forming an injection-molded aperture in the resulting molded plastic article at the gate region.

    摘要翻译： 在此公开了将多个聚合材料流流共同挤出到模腔中以产生在制品的浇口区域中具有注射成形孔的模制塑料制品的方法和系统。 一种方法包括提供具有第一直径的远端部分和具有小于第一直径的第二直径的中间部分的阀销，并且提供限定对应于所得模制塑料制品的形状的空腔的模具。 模具具有与模具的浇口区域对准的凹部，延伸到模具中并且构造成当阀销的远端部分延伸超过浇口区域时，容纳阀销的远端部分。 该方法包括将阀销的远端部分推进到凹槽中，直到阀销的中间部分至少部分地延伸到浇口区域内，从而在浇口区域处形成用于组合的聚合物流进入空腔的流动路径 形成具有至少一层第一聚合物材料和至少一层第二聚合物材料的模制塑料制品。 该方法还包括将阀销的中间部分从浇口区域中取出，从而在浇口区域形成模制的塑料制品中的注模孔。

    摘要： Disclosed is a removable erosion-control and fencing (“REAF”) system for shoreline preservation along a line defined by a plurality of posts. An exemplary REAF system comprises first and second post clamp pairs mounted to adjacent posts. Each post clamp pair “sandwiches” a post and is fixedly attached to the post by virtue of fasteners that lock one half of the post clamp pair to its other half. In this way, the post clamp pair “hugs” the post and is secured thereon without having to be permanently fixed to the post or damaging the structural rigidity of the post. Each post clamp pair includes a substantially vertical wall slot such that one or more cross-members may be received into the walls slots to form a wall section in a space defined between the adjacent posts.

    摘要： A coinjection molding apparatus is disclosed that provides first and second material melt streams to a nozzle. The nozzle defines a first material melt passage for receiving the first material melt stream, a second material melt passage for receiving the second material melt stream and an outer layer melt passage, which receives a portion of the first material melt stream from the first material melt passage. The first material melt stream from the first material melt passage forms an inner layer of a molded article, the second material melt stream from the second material melt passage forms a core layer of the molded article, and the first material melt stream from the outer layer melt passage forms an outer layer of the molded article, wherein the three melt streams combine prior to entering a mold cavity.
