High automatic stacking of distribution transformer cores – Ground for smart manufacturing

The newly developed GEORG autostack 400 is an offline system for the automatic stacking of distribution transformer cores, developed within the cooperation between GEORG and GÜDEL.

This highly automated system is equipped with an interface to GEORG core cutting lines and an integrated data management for core production. The direct data transfer from the cutting line to the robot unit makes time-consuming manual processes redundant.

By this data coupling, the new systems can be easily integrated into digitally networked environments and thus prepare the ground for industry 4.0 / IoT.

GEORG and GÜDEL are looking forward to continue their cooperation in the field of automatic core stacking by developing autostack systems for medium and large power transformers.

Partnership between LTC and GEORG extended

LTC recently achieved pre-acceptance for two new GEORG electrical steel production lines. The highly specialized lines are tailored for production in electrical steel service centers and are equipped with most of the features of a full-blown high-performance slitting line.

They feature a level of automation unparalleled in this sector, very high production speeds and a high production capacity.

3D Printing

Sven Helsper, former working student at GEORGinnovation, dealt with 3D printing as part of the additive manufacturing project. His task: Find components that are suitable for additive manufacturing, using a methodology based on filtering and specific criteria.


The opportunities of 3D printing lie in saving manufacturing costs, but also in increasing performance by unifying assemblies. The future application areas of 3D printing are manifold, for example, our customers can benefit from the new spare parts manufacturing technology in GEORG Service.
