Plastic cutting knives for pelletizer machines

Plastic cutting knives for pelletizer machines is a plastic granulation tool with dozens of outer diameters, requiring each blade to be on the same axis rail. The smaller the work error, the higher the accuracy of the cutter cutter, and the more beautiful the particles cut. Therefore, there are very strict requirements for blade welding. The cutter  materials include high-speed steel, SKD, and hard alloy steel. For acid resistant materials, high-speed stainless steel (9Cr18MoV) is selected as the cutter material, greatly improving the working efficiency of the cutter。 

The main materials used for the cutter blades include Carbon steel 45 #, 40Cr, 50CrV, and high-speed steel. Among them, 45 # steel is widely used in small pelletizers, with lower material prices and better hardness and strength. For large and high-performance pelletizers, materials such as 40Cr, 50CrV, and high-speed steel are more suitable. When selecting materials, factors such as strength, wear resistance, and fatigue life need to be considered.
