Choosing Used Plastic Equipment
Machinery and
equipment for manufacturing plastic lumber is typically made to order by
the equipment supplier. Many suppliers use only new equipment. However
considering the variations in the recovered plastic other suppliers have
elected to use good
remanufactured plastic lumber equipment in order to
minimize the investment required.
Cierra Industries of Auburn NY assembles plastic lumber lines from
rebuilt used plastic equipment. It is estimated that rebuilt machinery
will cost only fifty percent of the price of new equipment and give
service of up to 90% of new equipment. They also offer technical
assistance and formulations of plastic lumber recycled plastic mixtures to
meet specialty needs.
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.
