Types of Pelletizing Systems

1. Strand Pelletizer
Extrudate is cooled in a water bath and cut into pellets after solidifying.
✅ Ideal for: rigid polymers, fillers, wood-plastic composites (WPC)

2. Water Ring Pelletizer
Pellets are cut at the die face and cooled instantly in a water ring.
✅ Ideal for: soft plastics like PE, PP, EVA, TPU

3. Underwater Pelletizer
Cutting is done under water; suitable for high-output and viscous materials.
✅ Ideal for: TPU, PA, high-end resins

4. Air-Cooled Die Face Pelletizer
Pellets are cooled using air; simple and cost-effective for lower outputs.
✅ Ideal for: PVC, recycled plastics

5. Hot Die Face Cutter
Pellets are cut hot at the die face, often used in masterbatch production.
✅ Ideal for: pigments, modified materials
