Equipment selection
Choose equipment for your material
A plastic pelletizer converts prepared plastic scrap into pellets through extrusion and cutting. Amstar manufactures plastic pelletizing machines and connected systems in China for recycling plants worldwide. The appropriate line depends on the polymer, feed form, moisture, contamination and the quality required from the recycled pellets.
Choose a plastic pelletizer for your feedstock
For flexible materials, compare our water ring pelletizer for clean PP and PE film with the pelletizing line for washed film regrind. Clean production offcuts and washed post-consumer film enter the process in different conditions. Feeding, moisture removal and melt filtration should be selected accordingly.
For rigid material, review the HDPE flakes pelletizing machine. For prepared PET bottle flakes, see our PET flakes pelletizer. The product pages describe the equipment and help establish which feed preparation stages belong upstream of extrusion.
Extrusion, filtration and pellet cutting
A pelletizing line connects material feeding, melting, filtration, cutting and pellet handling. Compare single screw plastic pelletizers and twin screw systems, or read our single vs twin screw pelletizer guide. The choice should follow the processing task rather than screw count alone.
For suitable scrap and output requirements, a waterless pelletizing machine provides another process option. Discuss your material with Amstar before selecting a cooling and cutting method. A cutting granulator, also called a plastic crusher in some markets, produces solid regrind; it does not replace extrusion pelletizing.
Plan a complete pelletizing line
Send the polymer type, feedstock photographs, contamination details, moisture condition and required production capacity. Explain whether material comes from a washing line or directly from manufacturing, and describe how the pellets will be used. Use our recycling equipment budget guide to understand quotation scope, then request a pelletizing line proposal matched to your plant.
