Planetary Roller Extruder
PVC220 Planetary Roller Extruder 38CrMoAIA / 9Cr18MoV With 950HV - 1020HV Hardness
Planet roller extruder is composed of central shaft, planet shaft, rolling stuff cylinder, heating and cooling parts, nozzle and so on. It has better plasticization, self-clean, higher productility, longer life than single or two shafts extruder.
Due to the more contacting area, it has the optimum heat exchange rate and can reduce the material of retention time and cut down the cost of stabilizers and lubricant.
1. Materials: 38CrMoAIA, 9Cr18MoV
3. Depth of nitration case:0.5-0.8mm
4. Hardness of nitration: 950-1020HV
5. Fragility of nitration: Less than grade 1
6. Roughness of the surface:Ra 0.4um
7. Linearity of the screw:0.015mm
8. Chromium-plating layer thickness:0.03-0.08mm
9. The surface hard chromium plating hardness after nitrogenation:>=950HV
10. Guarantee: Common Nitrided: approx 2 years Bimetallic : much longer life time
1) The "PRE", a series of planetary roller extruders, experiences rolling and extrusion in configuration that a planetary screw is inter-engaged at a centerof a main SCREW and BARREL which are screwed in a shape of helical gear at 45 degree.
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 plasticmelt 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-temperatureforming 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 mainspindle 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 withshort 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.
