Twin screw extruders
The robust design and controls with proprietary software enable you operators to achieve higher productivity at each stage of the pipe extrusion process.
Twin Screw Extruders
Rollepaal offers a wide range of high capacity PVC extruders with screws from 22L/D up to 36L/D, depending on the application and output. The twin screw extruders (T-Rex) have a wide processing window for reliable pipe production with low reject rates. The screw geometry has been developed for a wide processing window and, in combination with the direct drive concept, provides a higher quality homogeneous melt. The innovative technological features of the T-Rex extruders deliver higher energy savings.
