LABORATORY TYPE
25 MM TWIN SCREW EXTRUDER

25 mm twin screw extruder has 42 L/D barrel design. The barrel
is designed as seven piece and resistant to high temperatures.
Every zones’ heater works by its own socket.

Extruder has a compact design with cooling bath and granulator. Designed for testing with raw material as minimum as possible
and works with the appropriate capacity for pilot production. Allows the processing of valuable polymers by segmented screw
and barrel design. The screw elements of the extruder can be redesigned for any different application by changing kneading,
mixing and cutting elements. The electrical panel is mounted on the machine frame.

CONTROL PANEL
Extruder control panel is designed for easy use. The screw and feeding’s speeds can be adjusted,
pressure and other parameters can be seen by 10' touch screen. The values in the formulas can be
saved to the memory. By the way, you can call the formulas stored in the memory by typing their
number or name and get the machine ready for use.

GRANULATOR

Conveyor belt or water bath systems can be used for cooling in the extrusion line. There are two
options with the machine. First, standard granule cutting, second is granule size adjustable model as
optional. (0.5, 1, 2, 3, mm)

VACUUM SYSTEM
Throwing out the gas with 120 mbar vacuum unit occured in the extruder that prevent formation of
bubbles and provide better quality product.
