TJ - 950 PET Sheet Extruder

TJ - 950 PET Sheet Extruder

Application Area

      This machine uses servo motor driven system and PLC control system with data operation, alarm. It adopts twin-screw co-extruding, suitable for producing PET, PLA sheet and recycled materials. It does not need the pre-crystallization drying system, low power consumption and high plasticizing e ect. The screw with modular structure and diversi ed portfolio is easier to maintain and change. The barrel is set with double vacuum suction hole to ensure a full emission of water vapor. The extruder is equipped with melting pump to stabilize the extruding pressure and ensure sheet thickness evenly .
