History

Years of foundation

In 1902 Margarete, née Schmidt (August 25, 1880, in Nuremberg), and Heinrich Diehl (born August 3, 1878, in Kölschhausen, died in Nuremberg) established an art foundry in Nuremberg. In 1914 they began producing rods and drop-forged parts which were launched at the Geuderstrasse site in Nuremberg.

In the next few years a metal producing plant and a modern extrusion press for the production of rods and tubes were constructed. In 1930 Karl Diehl, only son of Margarete and Heinrich Diehl, joined the parents’ company. He took on the metal processing company shortly before Second Worldwar. In 1938 they began building a new plant for semi-finished products at Röthenbach an der Pegnitz.

Historic years

During World War II, major parts of the plant facilities were destroyed by air raids and almost the entire company’s equipment was dismantled. On the basis of remaining presses, furnaces and machine tools, Diehl started to reconstruct its facilities. The foundry was converted from light to heavy metal.

In 1951 the setup of a 3,500-ton press took place. Diehl Metall started the production of synchronizer rings in 1956.

The company acquired Sundwiger Messingwerk KG in Hemer and became a manufacturer of rolled products. During the next years Diehl Metall built a new tube plant including a 1,600-ton press and established the first continuous dual-string casting plant for brass, with an annual capacity of 47,000 tons.

In 1973 Diehl do Brasil Metalúrgica was formed by Diehl Metall in São Paulo, Brazil.

From 1974 until 1984 the drop forge was expanded, another tube press was installed, a dust filtration system for the foundry was constructed and increased by the “Demag Continuous Casting System”. In 1977 the so-called “Schumag hall” was set up. In 1981 a new strip rolling mill at Sundwiger Messingwerk was erected.

In 1985 heat recovery systems were installed in the foundry. At the same time the laboratory building at Diehl Metall Messing was extended. In 1990 Diehl Metall took part in a pilot project by the “Berlin Department of Environment” and set up a new dust filtration system.

In 1988, in Shenzhen, north of Hong Kong/China, a slitting and service center was established. Diehl Metall Schmiedetechnik was relocated to new facilities.

New headquarters of Diehl Metall

In 1999 Röthenbach an der Pegnitz became the headquarters of the corporate division Diehl Metall. One year later Diehl Metall took over The Miller Company (US).

Company expansion

In 2002 Karl Diehl retired from the company and his first-born son Werner Diehl undertook his position as chairman of the board.

In 2003 Diehl Synchro Tec Manufacturing (Wuxi) Co. Ltd. was established in China. In 2006 Diehl Metall took over OTB Oberflächentechnik in Berlin and formed Diehl Power Electronics S.A.S. in France. One year later, the company took over Diehl Augé Découpage in France. In 2009 Diehl Metal Applications GmbH (DMA) with locations in Germany, France and China was established, the subsidiaries of Diehl Metal Applications being Diehl Metal Applications GmbH (Location Berlin), Diehl Metal Applications GmbH (Location Teltow), Sundwiger Messingwerk (Hemer), Diehl Augé Decoupage (Besançon), Diehl Power Electronic (Siaugues), Diehl Metall (Shenzhen). One year later Diehl Metall took over Zehdenick Innovative Metall- und Kunststofftechnik GmbH (ZIMK), which is also a subsidiary of Diehl Metal Applications. The DMA product development was established in 2011 and is involved in the development of the electrification of drive trains and the bonding of battery cells.[2]

In 2012 Diehl took over the Schempp & Decker Präzisionsteile und Oberflächentechnik GmbH in Berlin. In the same year Diehl Metal India Pvt. Ltd. was established in India.

In 2013 both of the companies OTB Oberflächentechnik in Berlin and Schempp & Decker Präzisionsteile und Oberflächentechnik were formed in a merger into Diehl Metal Applications GmbH.

Mobility

The number of cars will double up to two billions by 2025. Miniaturization, low fuel consumption and running smoothness gain in importance more and more. Synchronizer rings made of different materials ensure driving dynamics. The automotive industry is one of the customers of Diehl Metall. Therefore, the company supports the mega trend Mobility.

Water

Water is essential. Therefore, pure and germ-free drinking water on every continent is important. Diehl Metall‘s brands CUPHIN and AQCUARIN are used for fittings for drinking water applications. Due to the low lead content pure drinking water can be guaranteed.

Energy

The rising standard of living entails an increase of energy consumption. Materials, saving and releasing energy, become more important. Copper and precious metals possess a high conductivity and heat storage capacity. Using these materials increases energy efficiency. Even in the automotive industry energy conservation plays an essential role. Metal-plastic compound systems can reduce weight and reduce energy consumption.

Health

By 2025, the number of population will rise to over 8 billion. Often large gatherings of people hide underestimated risks. Hence health plays an essential role. Diehl Metall‘s material group CuTouch has an antimicrobial effect. It suits perfectly for the high expectations concerning hygiene.

Industry

The world population is growing. Due to this fact prosperity and consumption increase. Therefore, the industry needs raw materials with a low carbon footprint. During the production process, copper and copper alloys take up energy and accumulate it. Using these materials increases energy efficiency. By this means infrastructure, sustainability, quality of life, mobility, communication, alternative energies, health and supply are ensured. The products of Diehl Metall stand at the beginning of the supply chain for the industries. At that European standards and international regulations are taken into account.

Green technologies

Because of the climate change, environmentally friendly products and resource-saving manufacturing processes are getting more important. During the recycling process industrial metals are recovered. Besides, the company pays attention to climate-friendly copper alloys.
