Single Screw Underwater Pelletizing Extrusion Line

CYKF CK-S series Single Screw Underwater Pelletizing Extrusion Line can be applied to a wide range of applications. It is especially suitable for materials with high viscosity, low MI, and difficulty to be shaped, e.g., TPE and TPR.

Possible materials :
TPU, TPE, TPV, TPR, PP, PS, PLA, PVA, SEBS, EVA, Rubber, Hot-melt adhesive, Special resin, and Micro pellet, etc.

How It Works :

• Dosing feeder

  Dosing feeder adopts counter-rotating twin screw design, it makes transportation of materials more stable.



• Extruder screw

  Every section of the screw is designed according to material formulation. The purpose is to ensure the plastics are fully mixed to achieve high quality and high capacity extrusion performance. Our strict quality management guarantees good quality and long service life of the key component.



• Die

  Die material and mold runner must be selected and designed according to physical properties and characteristics of plastics to avoid occurrences of uneven material flow rate, retention, excessive molding pressure, in-mold temperature increase, decomposition and carbonization or other situations that may damage material properties of plastics.



• Underwater pelletizing system

  The die face of extruder is immersed in water. When melts exit the die holes, they are immediately cut into pellets by rotating knives, and cooled also transported by water to downstream equipment. Underwater pelletizing system is capable of handling virtually any type of polymer.



• Centrifugal dryer

  The equipment can eliminate moisture on pellet surface.



• Vibrating screening unit

  The machine body is made by stainless steel, it can filter out different size of pellets.



• Storage tank

  Storage tank is an important part of extrusion line. The tank body is made by stainless steel and has different capacities for choice. Big bag filling machine or bagging machine are also available on request.
