Definitions

  • U.S. Patent KTo. 6,191,228, issued to Thomas Nosker et al. discloses the make ⁇ up of a preferred plastic composite for manufacturing railroad ties. While most of the components of the Nosker plastic can be obtained from recycled or post-consumer products, it requires that each of the components of the composite be obtained in relatively pure form or waste stream, thus limiting the source of the components to those which are highly segregated.
  • the composite used in the Noskar patent has a relatively low melting point. This makes it difficult to machine. The heat generated by the cutting tool during machining melts the plastic as it cuts. This can gum up and dull the tool which leads to increased machine time and cost. It also makes it difficult to maintain the correct tolerances on the finished product. Finally once cooled the composition used in Nosker is relatively brittle. This causes breakage problems during shipment and installation and premature failure under certain use conditions.
  • the pelletized material having a desired moisture content When the pelletized material having a desired moisture content is achieved, it can be fed into an extruder 18.
  • the extruder melts and liquefies the pelletized material so that it can be pumped in a molten blend into a die, mold or other forming cavity to form 20 a composite railroad tie or other extra large structural objects.
  • Other extra large structural components could include but are not limited to light poles, utility poles, parking blocks and parking curbs.
