Automated extrusion process.
Maximum savings.

Extrusion 4.0 for your profile production:
DIGI.LINE from Greiner Extrusion controls the extrusion process digitally and optimizes in real time.

Digitalization must deliver measurable value. DIGI.LINE confirms this in the harsh production environment of extrusion. DIGI.LINE minimizes material consumption and increases output. Additionally, consistency and production reliability in extrusion is increased.

DIGI.LINE is the result of four decades of process experience from Greiner Extrusion; specifically the development, design, manufacture and tuning of more than 28,000 profile tools and 4,500 extrusion lines. Keeping you ahead in extrusion.


Networked extrusion line
with recipe management.

The new 15" DIGI.CONTROL connects all line components and centrally controls the entire extrusion process. For complete reproducibility and fast start-up, the recipes are stored with the set processing conditions and are available for future production. This ensures an automated and error-free reproduction of the process parameters in subsequent productions.


provides exact geometry of the profile.

With FLOW.MATIC the functional dimensions of the full profile sections are ensured automatically, within seconds and permanently. FLOW.MATIC builds on proven FLOW.CONTROL technology from Greiner Extrusion.
FLOW.MATIC measures the filling degree of the individual full profile sections and closes a control loop together with the die function. This results in highly consistent profile measurements – without the need for manual operation. The settings can be reproduced with DIGI.CONTROL at any time.


with SHAPE.MATIC keeps your profile in shape.

The DIGI.TANK system plays an important role in the connection of process parameters. With DIGI.TANK water level, water flow rate and vacuum settings can be controlled automatically. Backup and reproducibility of the process data are ensured in connection with DIGI.CONTROL.
Automated control of the vacuum settings (for example in the case of nominal dimension deviations that are automatically detected by an in-line profile measurement) ensures maximum consistency of the geometry of the profile. Compared to conventional tank systems, a potential source of error can be reduced to a minimum.


with WEIGHT.MATIC saves materials.

DIGI.SCALE in conjunction with WEIGHT.MATIC ensures fast and precise digital in-line profile weighing. This considerably reduces the profile weight and thus the profile costs. Trends in profile weight development can also be called up at any time using permanent data recording by DIGI.CONTROL. Additionally, the Greiner DIGI.SCALE is equipped with LED monitoring.
