Granulating knives are mostly used for plastic recycling or for manufacturing of PE, PP, PET, HD.

 

Granulating knives are made of tool steel with a high grade of chrome which provides high surface hardness, good toughness and strength and very good wear resistance, they are processed on the most recent machines for mechanical treatment. For quality industrial granulating knives the thermal treatment is crucial, therefore are granulating knives carefully thermal treated in the computerized vacuum heat-treatment facility.
