How the extruder works
Extrusion is a method for continuous production of space products in the string. This is done directly in the manufacture of pipes, tubing or profiles.
The Extruders most significant parts are plastic ring screw and barrel. The screw rotates in the cylinder, entering and carrying plastic material that may be
in the form of powder or
granules.
By reducing the screw thread of Hosts volume in the feed direction
compresses the
plastic while the pressure increases. In
addition to the heat out of the plastic ring by heating the
cylinder wall from
outside and through the screw friction.
The plastic
coated material
is homogenized and extruded through a nozzle to the desired profile. The material is now
still so hot
that it is not as
stable and therefore requires
a screed in which the substance is
pulled at a steady speed.
In connection with the
material left the
extruder cooled substance in cooling
water and then cut the substance to the desired lengths on
reels.
