Planetary Roller Extruder
Insulate Planetary Roller Extruder , Planetary Roller Screw For Plastic PVC Film
Planetary screw barrel assembly consists of a central spindle, a planet shaft,rolling barrel,outer shell,heating and cooling and the nozzles.Structure of the module system,has good flexibility.The contact area is the previous single shaft and two-axis extruder five times,the section shape of molten material in favor of the highly dispersed and uniformly,so it can get high quality products.And it's mainly used for heat sensitive materials,hard and soft PVC calender with discharging.Can also be used for the for the extrusion of ABS,TPO,TPU and filled polyolefin smoke and binder mixture.Having good plasticizing effect,self-cleaning performance,high output,long span life etc.
Planetary screw specialized in:
1. rigid PVC products: plastic sheet, PVC medical sheet, PVC card substrate, PVC poker card meterial, PVC watches sheet, colored PVC sheet
2.semi rigid PVC products: semi rigid PVC adhesive tape, printing cloth, advertising materials, light box cloth, decorative materials(film)
3. soft PVC products: soft PVC tape, all kinds of inflatable toys, raincoats, plastic film materials, salt film, home textile packaging.

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.
Planetary Extruder Mainly used in the production below:
