When To Use Flow Molding to Make Plastic Wood

Two main methods are used to manufacture plastic wood and lumber.
These are Flow Molding and Plastic Extrusion. Both methods incorporate plastic extruders in the process but differ in the forming technique.

Which process should be used   Flow molding or Extrusion to make  Your Recycled Plastic Lumber product?

The specific forming process, either  flow molding or extrusion is dictated by the size and shape of the "Recycled Plastic Lumber"  to be manufactured.
If the board is a large piece with a length of no more than ten feet,   then one can consider flow molding.   Flow molding is the process of extruding melted plastic directly from the plastic extruder into a mold of the shape required. However shapes that are to long or too thin will create excessive pressure during the filling of the plastic lumber mold to be used successfully.

In Line Plastic Extrusion of Plastic Lumber

A long board of recycled plastic lumber should be manufactured by using "In Line Plastic Extrusion." This is a process where the recycled plastic is continually extruded through a die into a forming tank and then is cut to length.
