The ohm Häner Metallwerk GmbH & Co. KG (proper spelling OHM & HÄNER) is founded by Paul Ohm and Alois Häner 1961 foundry for non-ferrous metals , based in Olpe - Dahl / Friedrichsthal in North Rhine-Westphalia . The owner-managed medium-sized company produces workpieces made of copper and aluminum cast alloys for machine and device construction as well as for the automotive industry in two plants . Individual systems were funded by the Federal Environment Agency, among others, and were pilot projects that were unique worldwide when they were commissioned.

history

In 1961, master foreman Paul Ohm and lathe operator Alois Häner founded Ohm & Häner in the Friedrichsthal district of Olper as a company for the production of ready-to-install cast parts. Initially a kind of garage company with ten employees, the workforce grew to 39 by the end of the 1970s. The greatest development began in 1980 with a 345% increase in sales in ten years. During this time, the plant was expanded and expanded several times.

For the production of prefabricated parts for immediate installation, Ohm & Häner had a mechanical production area connected to the foundry right from the start, initially with simple, later with program-controlled lathes and milling machines. In 1985, larger CNC-controlled traveling column machines were added.

In 2005, the final machining was extended by an additional hall with a neutral energy balance. The system was heated with waste heat from the foundry and, if required, cooled from 18 geothermal probe boreholes, each 100 m deep, using cooling units. Milling / turning centers such as the DMC 125 FD in duoblock design were used here.

As of 2007, Ohm & Häner developed plans for an additional sand foundry as part of further expansion . A new location in Drolshagen had become necessary because the Friedrichsthal Siege-Weiste development plan of the city of Olpe, which was required for an expansion of the main plant, was rejected because of problems relating to missions and a legal action brought before the Higher Administrative Court . The factory building with a cast glass facade was planned by Ehrengruber Architekten from Olpe and erected in 40 weeks on a 70,000 m² site in the Buchholz industrial park. When production started on September 10, 2008, the plant was one of the most modern aluminum foundries in Europe .

In 2010, the AiF Projekt GmbH in Berlin approved the funding of a bilateral research project with the Bergakademie Freiberg , the University of Siegen and Heinrich Wagner Sinto Maschinenfabrik GmbH with a project volume of one million euros as part of the Central Innovation Program for SMEs (ZIM) . The aim of the project to optimize foundry production processes by using knowledge-based control loops based on real-time process data was to continuously evaluate the quality of green sand molds directly during the molding process by integrating the latest sensor and camera technology into the HWS molding system at the Drolshagen plant. On this basis, an innovative control system was built that led to the optimization of the production of cast parts. The first results were presented at the GIFA foundry trade fair in June 2011 in Düsseldorf .

On the basis of these research results, Ohm & Häner developed a new type of sand processing from 2012 with funding from the Federal Environment Agency, which enabled a complete separation of molding material and foreign matter in the aluminum sand foundry and thus the use of new sand and bentonite as well as the generation of waste in the form of foundries. Used sand reduced. An essential part of the system is an optical scanner, as it was originally developed for recycling tasks. It recognizes the impurities remaining in the molding material and sorts them out with almost no residue. The pilot system built by the Eirich company in Hardheim was unique in the world at the time the project was implemented.

On September 29, 2011, the resolution was adopted in accordance with § 2 BauGB to the development plan no. 110 special area Metallwerk Friedrichsthal-Im Grüntal by the city of Olpe. The primary urban development goal was

"To secure the site of the metal works Ohm & Häner with planning and to enable an expansion that is compatible with the immissions protection claim of the surrounding residential development."

To implement this, an urban development contract was signed with Ohm & Häner, in which the company committed itself to various measures such as the construction of a noise barrier and mandatory rest periods. After early participation by the public in a citizens' meeting on November 24, 2011, the public exhibition took place from November 30, 2015 to January 8, 2016. The planning area covers 10.7 hectares and, according to plans by Ohm & Häner, is to be used for the construction of a new foundry with ancillary facilities as well as a further 9,000 m² factory building for mechanical processing.

Significance for the industry

From 2008 Ohm & Häner operated the most modern sand foundry in Europe. The results of the bilateral research project on Complex Event Processing (CEP) systems, which have also found their way into practice-oriented study and diploma theses, have been published regularly by the University of Siegen in an international context. In 2010 they received the Best Paper Award at the eKNOW (Second International Conference on Information, Process and Knowledge Management St. Maarten, Netherlands Antilles) and in 2014 the IHK Siegen award. At that time there were twelve chairs worldwide that dealt with this topic. The company was one of the first and the only foundries in the world to use such systems in their production. The 2014 book The Concept of a Real-Time Enterprise in Manufacturing describes the CEP and Auto-EDA ( Event Driven Architecture ) systems developed and used by Ohm & Häner .

The MikroSort sand preparation developed by Ohm & Häner in 2012 is considered a success story in the environmental innovation program and was unique in the world. Because of these innovations, Ohm & Häner is considered a model company .

Dr. From 2012 to 2013, Ludger Ohm was Vice President of the Association of German Foundry Professionals. V. (VDG).
