Wanrooe designs and manufactures plastic pelletizers configured to each customer’s material, capacity, and output requirements. Our range covers:
Feed systems — Hopper feeding, force feeder, shredder-integrated
Cooling methods — Air-cooling, water-cooling
Cutting systems — Die-face cutting, water-ring cutting, noodle (strand) cutting
Extrusion stages — Single-stage and two-stage configurations
Cutting System Options
Noodle (strand) cutting — Molten plastic extrudes into strands, cools in a water bath, then cuts into cylindrical pellets. Simple, reliable, and suited to heat-sensitive materials.
Water-ring cutting — Molten plastic exits the die directly into a rotating water-ring chamber where blades cut hot pellets. Faster, more compact, and produces rounder, more uniform pellets. Preferred for high-output lines and materials that tolerate direct water contact.
Two-Stage Pelletizer for Printed Film
Our two-stage system is purpose-built for PE and PP flexible packaging — printed or plain. The first stage degasses and filters heavily printed or moist material; the second stage homogenizes and builds pressure for cutting. Key features:
Hopper feeding — Compact layout, lower energy use, high pellet quality
Two-stage extrusion — Twin extruders with dual filtration handle heavy ink and residual moisture that would jam single-stage machines
Water-ring cutting — Stable, uniform pellet shape with consistent dimensions
Capacity and Feeding Options
Standard models range from 80 to 1,000 kg/h. A force feeder is available for light, bulky materials like crushed film or foam. The auger compacts fluffy feedstock into the extruder throat, preventing bridging and ensuring consistent throughput.
What It Processes
Primary materials: HDPE, LDPE, PP film and regrind
Ideal for:
Injection molding in-house waste (sprues, runners, rejects) — clean, uncontaminated, ready for direct recycling
Washed post-consumer flakes and scrap
Packaging film: commercial bags, garbage bags, agricultural film, food packaging, shrink and stretch film
Plastic pelletizer produces high quality reusable pellets. The produced pellets from Plastic pelletizer can be put directly back to the production line, mostly blown film or pipe extrusion processes.
FAQ: Plastic Recycling Pelletizer
When do I need a two-stage pelletizer vs. single stage?
Two-stage is essential for heavily printed film, moist material, or high-contamination feedstock. The first stage filters and degasses; the second stage builds clean, consistent melt pressure. Single stage works for clean, dry in-house scrap.
Can I run both film and rigid regrind on the same machine?
Yes, but not optimally. Film requires lower compression screws and force feeding; rigid regrind needs higher torque and different screen packs. If your mix varies, specify a versatile screw design or plan for quick-change components.
What determines pellet quality?
Melt temperature stability, filtration fineness, and cutting consistency. Variation in any of these produces oval pellets, tails, or dust — all of which affect downstream processing and selling price.
