摘要：
Thermoplastic polymers, rubbery polymeric components and reinforcing fillers are mixed and heated to a range of 380° F. to 440° F. The resulting mixture is then fed into a Banbury mixer, with the resulting mixture fed into a diverter feeding two molds. The velocity of the piston of each mold being filled is controlled to thereby control the density of the molded product along its length. As each mold is filled, it is deposited in a cool water bath (50° F.-60° F.) while the next mold is being filled. The molds are sequentially transferred to an air cooling rack to complete the process. A texture, generally comprising indentations perpendicular to the longitudinal axis on the molded object, provides a frictional surface between the railway crosstie and the ballast beneath the crosstie.
摘要（中）：
将热塑性聚合物，橡胶状聚合物组分和增强填料混合并加热到380°F至440°F的范围。然后将所得混合物进料到班伯里密炼机中，将所得混合物进料到分流器中，进料两个模具。 控制每个模具的活塞的速度，从而控制成型产品沿其长度的密度。 当每个模具被填充时，将其沉积在冷却水浴（50°F-60°F）中，同时下一个模具被填充。 将模具顺序地转移到空气冷却架以完成该过程。 通常包括垂直于模制物体上的纵向轴线的凹痕的纹理提供铁路搭扣和交叉柱下方的压载物之间的摩擦表面。
