Rena Technologies GmbH, headquartered in Gütenbach, Germany, acquired Austria-based Hirtenberger Engineered Surfaces (HES) on July 27, and has since rebranded it as Rena Technologies Austria, establishing a new Additive Manufacturing hub for the group. 

HES is known for its development of the Hirtisation technology, a high-performance tool for post-processing metal additively manufactured parts. The automated process is said to be precise and suitable for mass production in metal Additive Manufacturing, offering an alternative to conventional post-processing methods.

The existing HES team and its Hirtisation technology will be integrated into the Rena corporate structure. 

“The outstanding expertise and efficient implementation of modern production machinery designed to respond to customer needs immediately impressed us,” stated Peter Schneidewind, Rena’s CEO. “Hirtisation technology complements perfectly Rena’s product portfolio.”

As Rena Technologies Austria, the site will operate as a hub for the groups Additive Manufacturing activities. It will also function as a technology and development centre for all aspects of electrochemical surface finishing.

Wolfgang Hansal, Managing Director of HES and designated Managing Director of Rena AT, commented, “We are looking forward enthusiastically to working with our new colleagues at Rena because we can exploit Rena’s worldwide network as a launching pad for marketing our technology globally.”

“The first industrial machines have already been successfully introduced to the market,” reported Michael Escher, Managing Director of the new Rena AT. “Together with Rena we can speed up the establishment of our cutting-edge technology. Additive Manufacturing is becoming a building block of industrial production chains. With Rena Additive Manufacturing we can shape this process actively and gear up for growth.”

Schneidewind added, “The innovative segment opens a new and promising chapter with tremendous growth potential for Rena.”
