PVC Pelletizing Extrusion Line

CYKF is well-known in PVC extrusion. Our CK-DT series Counter-rotating Twin Screw Extruder is especially designed for PVC. The available screw diameter is between 55 to 130mm. We never stop improving our PVC extrusion technology and we love sharing ideas with customers. Our in-depth understanding of PVC enables us to design better extrusion lines compared to other competitors. CYKF’s PVC extruder is high-efficient and durable, its outstanding performances has earned highly praises from global users.

Possible materials :
UPVC, CPVC, Medical grade PVC, Soft PVC, Rigid PVC, Foam and wood powder additives.

How it works :
①Hopper (Force feeder/Dosing feeder) ➜ ②PVC extruder ➜ ③Die face pelletizing system ➜ ④Cyclone tank ➜ ⑤Vibrating cooler ➜ ⑥Storage tank

The mixed materials are delivered by hopper to PVC extruder for extrusion. The vacuum system of extrusion machine can remove waste gas during production. The melts come out from the die and are cut into pellets by die face pelletizing system. The pellets are transported to cyclone tank by air and then cooled by vibrating cooler before delivering to storage tank.

• Hopper
  

  Both force feeder and dosing feeder are available on request. The design of force feeder is able to avoid possible bridging during feeding and it can evenly mix raw materials. It is a standard equipment for soft PVC. As to dosing feeder, it adopts counter-rotating twin screw design and can make transportation of materials more stable.



• Extruder screw
  

  Extruder screws are customized according to PVC formulations. From steel selection, machining accuracy to quality management, we have strict standard procedures to ensure good quality and long service life of these key components.



• Die
  

  CYKF estimates material properties and characteristics for selecting appropriate die material in combination with optimized runner design, that effectively avoids destruction on material properties due to excessive die temperature, uneven material flow rate, material jamming, excessive die pressure, decomposition and carbonization, etc. The die of the PVC extruder is designed with quick clamping in combination with linear guideway, making die open/close and cleaning easy and fast.



• Die face pelletizing system
  

  The PVC pelletizing machine utilizes a special cutter hub, providing convenient cutter hub dismantling and calibration.



• Cyclone tank
  

  Cyclone tank can process initial cooling for plastic pellets.



• Vibrating cooler
  

  Vibrating cooler removes adherent dust and cools plastic pellets evenly and rapidly.



• Storage tank
  

  The storage tank is to store plastic pellets. It is made by stainless steel and has different capacities for choice. Big bag filling machine or bagging machine are also available on request.
