Tel.: +86-13855519988Specifically 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.

FAQ:
Q1: What are the common materials used for pelletizer blades?
A: Common materials include high‑speed steel (W6Mo5Cr4V2), cemented carbide (YG8/YG15), and powder metallurgy steel (ASP®). High‑speed steel offers good cost‑performance, cemented carbide provides excellent wear resistance, and powder metallurgy steel combines high hardness with toughness, suitable for high‑load, high‑precision pelletizing applications.
Q2: Which plastic materials are suitable for these pelletizer blades?
A: They are suitable for general plastics such as PP, PE, ABS, PVC, as well as polyester chips (PET) and other chemical fiber materials. We can also customize materials and edge designs for special plastics (e.g., reinforced plastics, engineering plastics).
Q3: What are the pelletizing methods and how do I choose the right blade?
A: The main methods are underwater pelletizing, strand pelletizing, and die‑face pelletizing. Underwater pelletizing requires blades with good corrosion resistance and high sharpness – we recommend cemented carbide or stainless steel. For strand and die‑face pelletizing, high‑speed steel or powder metallurgy steel are suitable options. We can recommend the most compatible blade based on your pelletizer model and process.
Q4: What is the typical hardness range for pelletizer blades?
A: High‑speed steel blades typically range from HRC 58‑65, powder metallurgy steel up to HRC 58‑67, and cemented carbide blades range from HRA 87‑91. The choice of hardness should balance wear resistance and impact toughness; we can match the optimal hardness to your specific material and production volume.
Q5: How can I tell when pelletizer blades need replacement?
A: When you observe uneven pelletizing, increased particle size deviation, severe stringing, increased surface burrs, or visible dulling or chipping of the cutting edge, it indicates that the blades need replacement or resharpening. Regular inspection and establishing a scheduled replacement cycle will help maintain product quality and equipment efficiency.
