PRE Series Planetary Screw Extruder
PRE planetary screw roller extruder series has an out-standing capability in mass production of many products because it uses variety of plastic resins. It fixes the screw developed by planetary screw into the center of the main screw & barrel whose screw barrel, a plastication device, is made of screws in the helical gear shape and is angled at 45' and revolves androtates to produce rollers and other extrusion products. It enables the best homogenitation and distribution effect because rolling and extrusion are performed at a rather low temperature in the space between the put-together screws. Therefore it achieves no change in properties in matter, which is the characteristic of a low-temperature molding extruder.
