Extrusion is a continuous process by which the extruder mixes, melts, and meters the plastic.  The melted plastic

is then pumped through the desired shape die.  Once the formed extrudate leaves the die it is cooled and

supported by the waterbath.  The haul-off equipment pulls the extrudate through the bath.  Upon exiting the bath,

the plastic piece is solid and can be cut or spooled.
