Pleissner Guss Invests €6 Million to Support Growth in Rail, Wind Energy, Infrastructure and Defence

Pleissner Guss GmbH, a GMH Gruppe company, has completed a €6 Million modernisation program aimed at expanding its role as a key supplier to future-critical sectors such as rail technology, wind energy, infrastructure, mechanical engineering and defence. With this investment, the company has upgraded its facilities to produce more advanced and precise castings, including safety-critical components for demanding industrial applications.

“The aim of our investments was to bring the company's production up to the highest technological standard while ensuring that we are ready for future challenges,” explains Dr Tobias Dubberstein, Managing Director of Pleissner Guss GmbH. ”The improvements make Pleissner Guss more efficient, digitally connected, and sustainable. At the same time, we can now offer a broader range of casting solutions, from large components for wind turbines to safety-critical parts for rail systems and defence technology,” says the managing director.

A major milestone in this upgrade was the implementation of a fully digital metal shop. This system integrates all processes related to melting – from planning and alloy management to batch tracking – creating a smart, data-driven environment that supports precision and traceability across the production chain.

The investment also includes the installation of two modern Medium-frequency induction crucible furnaces with a total casting capacity of 10 tons and a fully electric heat treatment furnace. The existing secondary metallurgy was modernised with a new control system. These new systems significantly reduce energy consumption, eliminate fossil fuel use, and contribute to the GMH Gruppe’s goal of achieving climate-neutral production by 2039. The furnaces are designed for faster and more consistent melting, with lower emissions and minimal wear, which increases operational reliability and product quality.

The modernisation extends to the company’s product capabilities as well. A newly added block casting pit makes it possible to produce large forged and round blocks for high-end industrial uses, such as ring rolling mills and electroslag remelting processes. This positions Pleissner Guss well to meet evolving customer needs in technically demanding markets.

To ensure quality at the highest level, Pleissner Guss has also introduced state-of-the-art inspection technologies. A new optical 3D measurement system allows for precise comparison of cast components with customer CAD data, enabling the accurate inspection of complex geometries. A new, efficient linear accelerator has been added for non-destructive testing. This equipment allows internal defects like cracks or porosity to be detected without damaging the part, increasing the reliability and safety of final products.

In addition, the modernisation included improvements to process control and automation, enhancing both production efficiency and workplace safety. The integration of digital systems across the operation creates a seamless production environment that supports consistent quality and faster delivery.

With these upgrades, Pleissner Guss is now optimally equipped to support customers across Europe with advanced, sustainable, and high-performance casting solutions that are designed for industries which demand, to a special degree, traceability and innovation.
