| Extruder for
all applications |
 |
| |
| Application-tailored
extruder The series comprises machine sizes with screw diameters
of 20, 30, 45, 60, 75, 90, 120 and 150 mm. Different versions are
available with alternative gear ratios, driving powers and torques
so that an optimised specification with maximum efficiency can be
offered for a particular application. |
| |
| Output
capacities Our Extruder cover an extremely wide range of output
capacities. These are from 1,5 kg/h for the production of skin with
low speed smooth-bush extruders to over 900 kg/h for the production
of HDPE with grooved-bush sheathing extruders. |
| |
| Functionality
and Design Optimal functionality and perfect design are central
tasks to resolve by our team when they innovate and engineer the machines.
The features following from these guiding principles are good accessibility,
easy maintenance and minimised floor space requirements. |
