History

September 2020 – Commissioning of the extended workbench in the segment of investment casting for ferrous and non-ferrous materials. Expansion of NRU GmbH’s production capacities is thus fully available. By expanding capacities, we increase our production portfolio and competitiveness both in the prototype business from the number of pieces one up to small series orders.

August 2020 – Handover of the management and the company to Dr.-Ing. Tobias Schubert

With the realignment of the ownership structure, NRU GmbH is repositioned and thus placed on a new solid, future-oriented foundation.

NRU GmbH was founded in 1992 as NRU Präzisionstechnologie GbR by the three partners Dr. Jürgen Jahn, Dr. Ludwig Kant and Dr. Hubert Zeidler. In 1999 the company was renamed NRU Präzisionstechnologie GmbH and in 2007 the company name was changed to NRU GmbH. NRU GmbH is based in Neukirchen near Chemnitz (Saxony).

The objective when the company was founded was to combine classic manufacturing processes, such as investment casting, with new developments from the field of rapid prototyping, such as stereolithography, and thus to enable the effective production of investment castings in small quantities.

From this, the three current main business areas have developed: Investment Casting – Rapid Prototyping – Plastic Vacuum Casting. Our first company headquarters is still known to many of our customers as the “Kindergarten” – a former nursery.

Since the end of 2006, our company has been located in a modern office and production building in the industrial area of Neukirchen in the Ore Mountains.

The production area covers approx. 1500 square metres. We have our most important customers in many different sectors, such as the automotive industry, the electrical industry, medical technology, mechanical engineering and equipment manufacturing.

In 2013, the course was set for the generation change in the company. Since the end of 2013, there has been a successor from each of the founding families. This should ensure the future success and continuity of our company.
