New design Automatic Extruder Planetary screw and barrel for plastic extruder machine
As a new type of extruder, planetary screw extruder is more and more widely used in PVC material production lines. Compared with the general conical twin screw extruder, the planetary screw extruder has the advantages of high yield, high efficiency and high plasticization.
| Material | 1)W6Mo5Cr4v2 2)38CrMoAIA(JIS SACM 645) 3)42CrMo(AISI 4140) 4)SKD61 5)S45C |
| The planetary screw barrel is mainly used for heat sensitive materials, such as processing rigid PVC. In the calender production line of PVC transparent chip, adopt planetary screw barrel to plastify and mixing raw materials for calender. It can make all melting materials, accessory ingredient and modifier uniformly mixing and dispersing. It has features of good plasticization self-cleaning, high productivity, long using life and so on. |
