Extruder's Components
Detailed Product Description
Screw
Screw material:38CrMoAlA, surface hardness could be HV900-950 after nitrited,with hardened depth of 0.4~1.2mm.Additionally, stellite screw(so called be-metal screw) could also be made, which has a layer of around 1.5mm thick stellite metal,and the surface hardness could be HRC58~62.Various types of screw could be designed so as to process different compound with mooney viscosity ML1+410030-120,and to get relatively high output with lower discharging temperature.
Barrel
This barrel is made of quality alloy steel,equipped with heating/cooling channels of drilled structure to control temperature.The inner surface of barrel could be nitrated with hardness of HV950-1000,nitrated layer arround 0.5mm thick;or inlayed with stellite metal(bi-metal),with thickness 1.5mm,surface hardness HRC60~64.Multi-row pins are arranged on the pin-type barrel in a way of fixed distance,pins are inserted into the barrel,nearly to screw thread channel along circumference.
Extruder head
Various heads such as those for pipe,strip,feeding for calender,and Tor Y head for rubber coating could be provided.Also duplex,triplex or multi-plex head for making profiles such as tread or sidewal of tires could be designed and manfactured.
