Core stacking tables and automized core stacking systems

GEORG precisionstack

Fully automatic and manual core stacking

Depending of requirements and customer request we offer solutions for fully automized and manual core stacking as well.

Our product line GEORG autostack which we developed together with our cooperation partner GÜDEL is an off-line stacking system for automatic stacking of distribution and power transformer cores.

In addition we still offer you our classic and proven core stacking tables for manual core stacking within our product portfolio. Further products complete the core stacking and banding process.

Fully automatic off-line stacking system

GEORG autostack 1000, driven by GÜDEL

Our portfolio of offline stacking systems which we have developed together with our Swiss partner GÜDEL is the most complex of its kind worldwide.

Article in Transformer Magazine

It enables stacking of small distribution transformer cores of about 100 kVA but also power transformer cores with 5 legs of above 1000 MVA.

GEORG autostack 400, driven by GÜDEL

The newly developed GEORG autostack 400, driven by Güdel, is an offline system for the automatic stacking of distribution transformer cores.This highly automated system interfaces with GEORG core cutting lines and features an integrated data management system.

The direct data transfer between the cutting line and the robot makes time-consuming manual process superfluous. Thanks to this data link, the new system can be easily integrated into the digital network of the production plant.



The GEORG autostack 400, driven by Güdel, is designed to work in combination with GEORG core stacking tables using pre-stack platforms on which stacks of previously cut core laminations are located. The laminations will be picked up by the handling systems with grippers according to the required stacking sequence and stacked on the automatic stacking station.

The design allows to move the table with the finished stacked core (in horizontal position) out of the unit and move another 2nd table in. This reduces non-productive times and allows customers to finalize the core (including secure tilting into vertical position) outside the autostack stacking unit.
