Extrusion - Process
ARITA
techniques used to manufacture thermoplastic sheet-
::Extrusion through a flat die.::
It has advantages and disadvantages depending on factors such
as type of polymer being processed, thickness and width of
sheet, and surface quality desired.
The classic machinery components for this process can
be
described as follows:
| • |
Resin is fed into an extruder where it is plasticated
into a melt. |
| • |
The extruder, consisting of a heated barrel with an
internal rotating screw, pumps the melted resin into a
flat sheet die which sizes the sheet (thickness and width). |
| • |
The sheet exits the die in a semi-viscous state and
travels through a series of rolls to cool. These rolls
also determine final sheet size, thickness, and width. |
| • |
The flat sheet may then be wound onto continuous rolls,
or "pre-sheared" into discrete lengths. |
