Rena Technologies acquired Hirtenberger Engineered Surfaces (HES) to venture into the additive manufacturing market. Hirtenberger’s existing team, process know-how and cutting-edge Hirtisation technology will be integrated into the parent company as Rena Technologies Austria (RENA AT), operating as a hub for activities in the additive manufacturing segment. Rena AT will also function as a technology and development center for all aspects of electrochemical surface finishing.

Hirtisation technology is at the core of the new Rena Technologies. The company says it is a high-performance tool for post-processing of 3D-printed metal parts; in particular, for surface finishing that permits the use of 3D-printed components. The process is precise, automated and suitable for mass production in 3D metal printing — as an alternative to conventional post-processing methods.

“‘Hirtisation technology perfectly complements Rena’s product portfolio,” says Peter Schneidewind, Rena’s CEO. Headquartered in Hirtenberg near Vienna, Austria, HES focuses on dynamic electrochemical surface technology. The H3000 and H6000 compact finishing modules are the first fully automatic machines for postprocessing 3D-printed metal parts.

Rena Technologies is a global manufacturer of production equipment for wet chemical surface finishing. Rena products are used in applications for semiconductors, medical technology, renewable energy and glass.
