The machine factory formerly Georg Dorst AG was a machine factory and iron foundry founded in 1891 by Georg Dorst in Oberlind ( Duchy of Saxony-Meiningen , today Thuringia ) . With a large number of patented developments, the company was the leading manufacturer between 1928 and 1945 and, from 1948, the only manufacturer in the GDR of machines for the automated manufacture of ceramic products. After an eventful history, the company was closed as the former VEB Thuringia Sonneberg after the Treuhandanstalt converted it into a corporation in 1994. The successor company founded in Kochel am See in 1949 , Dorst Technologies GmbH & Co. KG , still exists today.
history
1865-1918
In 1865 Georg Dorst founded a village smithy with a workforce of 6 in Oberlind ( Duchy of Saxony-Meiningen , today Thuringia ) .
After the number of employees had risen to up to 60 people, the company was converted into a family-owned stock corporation in 1891 under the name Maschinenfabrik, formerly Georg Dorst AG . The subscribed capital of the 210 founder shares issued on February 10, 1892 at 1,000 marks each amounted to 210,000.00 marks. In the same year investments were made in a steam engine and a steam boiler from the manufacturer G. Kuhn, Stuttgart-Bergdurch, and in 1912 in a steam engine from the Esslingen machine factory . A multi-page reference list from 1895 and an 80-page catalog from 1897 with more than 150 different machine types were evidence of the company's extensive activities throughout Europe , South America and Asia .
1918-1945
Immediately after the First World War , a hollow extrusion press for ceramic bodies was developed and a patent (DE333147A) was applied for in 1919 .
In the Weimar Republic , the share capital was probably due to inflation , with several capital increases from 1920 to 1924 to 2,000,000.00 Mark and by resolution of the Annual General Meeting on 16 June 1924 after the currency reform at 400,000.00 Reichsmark , divided into 2,000 ordinary shares to 200.00 Reichsmark each, converted.
With a large number of innovative developments, the company became the leading manufacturer of machines for the automated production of ceramic products from 1924 and was also known internationally. In 1933 the management consisted of the board member Otto Dorst as well as the supervisory board members Heinrich Scharf, Curt Craemer and Richard Schneider, the vice-president of the Gauwirtschaftskammer Thuringia. The purpose of the company at that time was: Operation and acquisition of systems that serve mechanical engineering and its ancillary trades. The production program consisted of: machines for the fine ceramics industry; special types of machines for chemical, paint, pencil and glass factories; Complete mechanical equipment for porcelain, earthenware, pottery, wall and floor slab factories, mineral mills, kaolin slurries, enamelling factories. The last ordinary general meeting took place on July 15, 1943.
1945–1990
After the end of the Second World War , the Dorst family had fled to relatives in Lüdinghausen in West Germany from reprisals by the Soviet occupying power . In 1949, a plot of land was acquired cheaply at Mittenwalder Strasse 61 in Kochel am See . Otto Dorst and Walter Schlegel founded a new company there with Dorst Keramikmaschinen-Bau and began a new production of the well-known machines from 1950 with a workforce of 18 employees. During this time I also came into contact with Otto Aßmann, who was head of the machine and construction department at Hescho in Hermsdorf until 1945 and presented his press machine development and procured two innovative presses from the Hescho era for use in powder metallurgy. Aßmann moved with his family and his engineering office to Kochel in 1958 and was significantly involved in the further development of Dorst's systems in the following years, but was never an employee of the company.
The trustee administration of the state-owned companies in Erfurt took over management of the original company from 1947 until 1948 when the final expropriation followed. The company was connected as VEB Thuringia Sonneberg to the LBH ( Association of People's Own Companies Land, Construction and Wood Processing Machinery Leipzig) and in 1952 it was affiliated to VEB Thuringia Feinkeramikmaschinen in VVB Land, Construction and Wood Processing Machinery, Plant I, Sonneberg 2. At that time, the company was the only manufacturer of machines for manufacturing ceramic products in the GDR .
1967 saw the merger with the machine factory and iron foundry Steinach with a total of 690 employees. For this core 1973 was Kombinat VEB Kombinat Thuringia for glass and ceramic engineering, Sonnenberg formed, which reports directly to the Ministry of glass and ceramics industry was under and were temporarily employed in which up to 3,260 people.
The development of new processes for the preparation of porcelain was the subject of a joint project of the parent company of VEB Thuringia Sonneberg, VEB Henneberg-Porzellan Ilmenau and the Technical University of Ilmenau . The result was a process for the simultaneous dewatering and cleaning of ceramic suspensions using pressure electroosmosis , which VEB Thuringia Sonneberg applied for a patent in 1989. The new process reduces the technical effort by two thirds and enables energy savings of up to 96 percent.
The Dorst ceramic machine construction with their owners Otto Dorst and Walter Schlegel in West Germany had grown. With systems for the manufacture of powder metallurgical products under the leadership of Otto Aßmann, the business area was expanded and a number of innovations such as a press for manufacturing dimensionally accurate compacts from powder material or presses for manufacturing plates were developed. Between 1953 and 1984 a total of 32 patents were registered and granted. Further manufacturing companies and subsidiaries were set up in Bad Kötzting ( Dorst Maschinen und Anlagenbau GmbH & Co. KG ), the USA and China, as well as sales and service branches in various parts of the world. In the 1980s, a technology center for research and development was also established.
1990-2010
After the turn of the Combine in Sonneberg in 1990 by the Treuhandanstalt dissolved and the individual holdings in corporations converted. In 1994, after unsuccessful privatization, it was finally closed. It is not known whether attempts were made to take over the old company again within the framework of settling open property issues or whether compensation was received.
The West German counterpart was restructured in the 2000s and has been trading as Dorst Technologies GmbH & Co. KG ever since . A small crisis between 2008 and 2009 with short-time working and downsizing was overcome and the company grew into the largest plant manufacturer in the Bad Tölz-Wolfratshausen district . At the time, around 12,000 machines and production systems from Dorst were in operation around 2000 customers in over 70 countries and the company stated that it was the technology leader in plant construction for ceramic and powder metallurgy production.
today
The family company is now known as "Dorst Technologies GmbH & Co. KG" and is an internationally active medium-sized group with six individual companies and a manufacturer of special machines for the manufacture of ceramic and powder metallurgical products. The shareholders are represented by a supervisory board. The business is run by a management outside the company. Around 2/3 of the turnover is achieved abroad. The company holds over 150 patents worldwide.
