Abstract

An improved mold and method of manufacture for an improved railroad tie or other structural member. The improved railroad tie or structural member being fabricated using an injection molding process with various thermoplastic resins and fillers. The improved mold used has a cooling cavity which helps cool the structural member while still in the mold. The improved insert allows an automated molding system to be used for greater production rates.
