Plastic recycling granulator knife

Specifically designed for plastic pelletizing, recycled plastic granulation, and polyester chip cutting in the chemical fiber industry. Suitable for underwater pelletizing, strand pelletizing, and die‑face pelletizing of various plastic materials. Manufactured from high‑speed steel, cemented carbide (tungsten steel), powder metallurgy steel (ASP®), and stainless steel, the blades undergo strict heat treatment and precision grinding to achieve high hardness, good toughness, and long‑lasting sharp edges. Widely used in production lines for PP, PE, ABS, PVC, and other plastic pellets, as well as specialized equipment for polyester (PET) chip cutting in the chemical fiber industry. The blades deliver uniform, stable pelletizing without material sticking or stringing, effectively reducing blade change frequency and improving granulation efficiency and product quality.
