1) The "PRE", a series of planetary roller extruders, experiences rolling and
extrusion in configuration that a planetary screw is inter-engaged at a center
of a main SCREW and BARREL which are screwed in a shape of helical gear
2) The planetary screw revolves and rotates on its axis, in order to
employ various resin
3) The extruder is special and applied to various product and mass production
4) In special, because the extruder supplies the rolling and extrusion
through space of the inter-engagement, it may plasticize the resin at a
low temperature
5) Through the inter-meshing action of the toothed planetary roller system
just one single revolution of the main spindle suffices to roll out the plastic
melt as many as 1,100 times, ensuring optimum plastification,
homogenization and dispersion
6) The "PRE" is a low-temperature forming extruder which may produce
produces without any change of properties owing to its low-temperature
forming and homogenizing
7) Combined rolling and extruding action: through the inter-meshing action
of the toothed planetary roller system just one single revolution of the main
spindle suffices to roll out the plastic melt as many as 1,100 times,
ensuring optimum plastification, homogenization and dispersion
8) Compared with other extruder designs, this system increases the contact
surface of the melt by up to five times
9) Low-cost formulation: the optimum heat-exchanging effect created by
the large contact surfaces of the planetary roller system in conjunction with
short residence time of the melt helps to achieve a considerable reduction
in formulation costs. Costly stabilizers and lubricants are reduced to a minimum
10) Self-cleaning feature: since all toothed components of the machine
constantly inter-mesh, no residual material is left in the machine when
changing over from one formulation to another. The system is change-over
from one color to another, results in no more than 5kg of scrap
