Applications
Detailed Information
Pelletizer blades (die face cutters) are critical cutting components in plastic recycling lines that convert molten polymer into uniform, homogeneous small granules. Rotating at high speed over a die plate, they shear the plastic strands emerging from the extruder and quench them instantly with water, ensuring consistent pellet size.
What Is Underwater Pelletizing?
Underwater pelletizing is a high-efficiency granulation method in which molten plastic is cut by rotating blades the instant it exits the die holes and cooled immediately in a water chamber. Compared with conventional air-cooled systems, it produces rounder, more homogeneous pellets and is used with a wide range of polymers including PE, PP, PET and PS.
Compatible Machine Brands
- EREMA: 46×24 mm and 46×13 mm — The world's most widely used plastic recycling system manufacturer; compatible with Intarema and Vacurema series.
- GALA: 40.6×20.6 mm — A leading brand in high-capacity underwater pelletizing systems.
- NGR: 44×20 mm and 44×13 mm — Austrian-origin, patented recycling technology; compatible with S:GRAN and P:REACT series.
Steel Types & Coating
- D2 Tool Steel: High-chromium cold-work steel, HRC 58–62. Outstanding wear resistance delivers extended service life on standard and high-throughput production lines.
- M2 HSS (High Speed Steel): HRC 62–64. Superior heat resistance prevents performance loss under heavy-duty conditions; provides the longest blade life.
- Carbon Steel: HRC 58–60. A cost-effective, reliable option for standard applications.
- TiN Coating (Titanium Nitride): Raises surface hardness to ~2300 HV, boosting wear resistance 3–5×; reduces friction and improves pellet quality. Applicable over D2 and M2 HSS substrates.
Applications
- Plastic recycling plants — PE, PP, PET, PS pelletizing
- Underwater pelletizing systems
- Hot die face pelletizing
- Plastic granule and compound production lines
- Polymer extrusion line output pelletizing
