Wide range of excellent rotor and stator knives for the highest quality granulating of plastic waste.

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 TRO granulating knives carefully thermal treated in the computerized vacuum heat-treatment facility.

The knives are mostly manufactured of material 1.2379 and hardened up to the hardness 55-60 HRC.
