How to Select
Plastic Lumber Equipment
The recovered plastic is cleaned, shredded, and ground using plastic
shredders and Granulators. The material is then run
through a plastic
extruders and mixed with foaming agents, UV stabilizers, and color
pigments.
When To Use Flow Molding to Make Plastic Wood
Which process should be used, flow molding or extrusion to make "Recycled
Plastic Lumber". 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 presure during the filling of the plastic lumber mold to
be used succesfully.
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.
Cierra Industries Incorporated of Auburn New York offers a free service
to help pick the proper plastic lumber machinery for most applications.
Plastic Lumber Materials
Recycled plastic lumber has been in manufactured since the early 1980s.
Plastic lumber is most commonly manufactured from post-consumer high
density polyethylene (HDPE), but linear low density polyethylene (LLDPE)
and low density polyethylene (LDPE) are also used. These plastic feed
stocks are derived from such raw materials as post-consumer milk jugs,
soda bottles, grocery bags, plastic wrap, bubble rap, detergent bottles,
and water bottles, and other used plastic commodities.
Used Plastic Lumber 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. It is estimated that used
rebuilt equipment will cost only fifty percent of the price of new
equipment.
