Introduction & Application of Our PRE Series Planetary Roller Extruder The "PRE" series of planetary roller extruder, 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 at 45°. The planetary screw revolves and rotates on its axis, in order to employ various resin  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.  The "PRE" is a low-temperature forming extruder which may produce without any change of properties owing to its low-temperature forming and homogenizing.   Why Choose  from Lanhang  1. Since1992, with more than 20 years' professional experience   2. Overseas service center available (in Europe, Japan, Dubai, etc.)   3. International CE, SGS, IAF, CNAS certification   4.

When machine working, generally machine can not touch the material. By red dot, machine can make sure the right loaction then marking on the surface of the item. Because machine working easily with high efficiency, it widely used in many fields, like marking on the kitchen tool,medical device, bathroom equipment and other industries. Besides, this kind of machine when working can not make any pollution, so we trust, it can use in our life more and more in the future.

The extruder has the advantages of multi-application, can be used for sheeting, filming instead by using banbury mixer/open mill mixer, and used for high capacity pelletizing, its capacity could reach to 2000kg/h.
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.
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.
Compared with other extruder designs, this system increases the contact surface of the melt by up to five times.
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.
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.
