SHJ Series Co-rotating Parallel Twin Screw Extruder (Comounding extruder, Compounding extrusion machine)
  • Applicable Products: Masterbatch, Filler and other kind of pellets(Granules), etc.
  • Applicable Processing: Polymer blending & filling modification, engineering polymer & glass fiber reinforcement, reactive extrusion, degassing & devolatilization
  • Alias: Twin screw extruder, parallel twin screw extruder, double screw extruder,co-rotating twin screw extruder,compounding extruder

SHJ series parallel twin-screw, co-rotating extruders are a high-efficiency compounding extruder. A parallel twin-screw extruder is equipped with force feeding system which can be used for feeding glass fiber, additives and other kind materials, it is ideal equipment for manufacturing the engineering plastic, glass fiber, high density master batch and so on products.

The screw of this co-rotation parallel twin-screw extruder is multi-section. Screw and barrel segments allow for customizing the length of the barrel and for selecting the optimum screw configuration to match the required compounded material characteristics. This ensures the very best plastification at maximum throughput rates. 

Co-rotating Parallel Twin Screw Extruders are used for:

  1. Polymer blending & filling modification
    Co-rotating twin screw extruders are suitable for extrusions of PE/PP/PS+SBS, PA+EPDM, PP+NBR, EVA+Silicon Rubber,PE/PA/PC/CPE+ABS(alloy), ABS+TPU, PBT+PET, PP+PE,PE/PP/EVA+Calcium carbonate/talcum powder/titanic powder, ABS/PC/PS+aluminum hydroxide/magnesium hydroxide/antimony oxide, PP/PA/ABS+ferrous powder/sulphuric powder/ceramic powder,etc.
  2. Engineering polymer & glass fiber reinforcement
    Co-rotating twin screw extruders are widely used for making kinds of boards, plate, such as PVC foam board, WPC(wood plastic composite) plate, and so on.
  3. Functional  parent  granula(pellet), and masterbatch
    Parallel twin screw extruders are very suitable for making combustion-supporting pellets(PP/PA/ABS/PBT+anti-burning agent and other auxiliary agents) and decomposing pellets(PE/PP/PS+starch).
    Masterbatch(PE/PP/ABS/AS/PA/EVA/PET+pigment and auxiliary material)
  4. Special material, powder coating material
    Co-rotating parallel twin screw extruders are very suitable for EVA heat-melting glue/polyurethane, fluorin rubber/fluorine plastics/PP cigarette filtering material and TPR sole material; HDPE/LDPE/LLDPE/MDPE/EVA/PVC/PP,etc.lnsulating cables/coatings,PE peroxide/silicon alkyl crossing cables/radialization crossing cables.
  5. Reactive extrusion, degassing & devolatilization
    Besides aboving, co-rotating parallel twin screw extruders are very suitable for making Polyamide condensate/polyamide melting polymerization/polyamide polyethene-adding/polycarbonate condensate, and Polystyrene oxide/high-absorbing resin/chlorine sulphur polyethylene, etc.
