Schoenenberger became involved with the plastics industry at an early stage, as a very renowned manufacturer of pelletizing systems was located in the immediate “neighbourhood”.
Together with this machine- and plant manufacturer, they developed cutting rotors with carbide inserts. This was a special field for Hermann Schönenberger, because he had already been producing carbide knives for the paper and printing industry since the mid-60s.
What began at that time with a “niche product cutting rotors” developed into a rapidly expanding and important business field.
Also through the takeover of a granulation expert, the know-how in this area grew very strongly.
- cutting rotor tool steel
- cutting rotor powder metal steel
- cutting rotor tungsten carbide
- cutting rotor stellite
Tooth profile; concentricity, and the material. These are the main characteristics that are important for a cutting rotor
The premium cutting blades from Schoenenberger convince through the use of a “high performance” carbide that meets the requirements of the chemical and plastics industry. They are available for all common strand pelletisers.
