Kobelco Stewart Bolling, Inc. products

The Kobelco Twin Screw Roller Head Extruder (TSR) is a specialized twin screw extruder with an inclined roller-head or “sheet forming die”. The machine is designed to accept material discharged from an internal intensive mixer and then form a continuous, seamless material sheet. The TSR is ideal for applications such as tire manufacturing, custom compounding, hose & belt and industrial rubber goods.

KOBELCO high-performance mixing technology reduces batch times with improved compound quality. Our patented mixer innovations drive greater output and batch uniformity with lower energy consumption. Our Internal Intensive mixers are available in a wide range of chamber volumes from a minimum 0.4 liter laboratory size to a maximum 699 liter production size. We offer three series of internal intensive mixers: The MIXTRON BB Tangential, MIXTRON BB Intermeshing and the Stewart Bolling Series.

Whether for mixing or sheeting, KOBELCO mills offer a multitude of features that will provide long life and precise material control.
