Vinyl post and
rail is manufactured through an extrusion process which is
defined as converting powder or granules into a continuous
uniform melt and forcing this melt through a die which
yields a desired shape.
Freedom Fence Company uses a co-extrusion system with two
(2) twin-screw extruders.
is added to each extruder and fused with heat and pressure
as it moves through the screws.
It is pushed
through an extrusion die at the desired profile.
The profile is
then pulled by a haul-off through a series of calibrators
and cooling spray tanks to cool the product to the desired
It is then
pushed through a cut-off saw and cut to the proper length.
The 1½” x 5½” Double Ribbed Rail is inspected for any
defects and four (4) locking notches are added to both end
of the rail.
The rail is then
packaged into 80 piece bundles and is ready for resale.
The 5” x 5” post is inspected and stacked on racks and moved
to a holding area until it can be routed by our CNC Router.
The CNC Router
cuts the holes into the posts to receive our 1½” x 5½”
double ribbed rail. The posts are then packaged into bundles
of 54 pieces ready for resale.
