Innovation is in our genes — since 1873

  • 1873

    26-year old Jakob Dieffenbacher establishes the Dieffenbacher company. He specializes in the manufacture of fruit presses, wine presses and cooking oil presses but also performs all kinds of fitting work and repairs, particularly on agricultural machinery. The premises are located in Kettengasse in Eppingen's old town. At this time there are five associates.

  • 1910

    A residence with an adjoining factory building is constructed in Heilbronner Straße and the company is renamed "J.Dieffenbacher Söhne" (J. Dieffenbacher & Sons). In 1910 the machine shop in the old town is handed over to Jakob's son Heinrich, while Wilhelm and Friedrich Dieffenbacher run the new factory. This is how the second generation is integrated into the family company. Father Jakob continues to play a part in the company until his death in 1929, assisting his sons with his knowledge.

    The product line is also expanded at this time and soon moves away from fitting work towards producing industrial products.

  • 1928

    The chemical industry develops phenolic resins that cure under pressure at high temperatures. The so-called hardenable plastic is named "Bakelite" after the Flemish chemist Baekeland. 

    The brothers react quickly and manufacture the first hydraulic presses for masses of Bakelite for the plastic industry.

  • 1952

    On 05/01/1952 Albert and Gerhard Dieffenbacher enter the family company and become the third generation to take over management: Albert Dieffenbacher is responsible for operation and all machine facilities with Gerhard Dieffenbacher in charge of design with the technical office, sales department and commercial department. It is to be the beginning of a successful working relationship.

  • 1957

    The first orders for exports to other European countries were received in late 1956/early 1957. Increasingly renowned customers are won on top of this, such as AEG, Siemens and Loewe. In addition to strong business for Bakelite presses and thermoplastic sprayers, a boom in the wood sector also occurs during these years.

  • 1960

    In 1960, in addition to the manufacture of the first polyester presses, a further step forwards is made in the plastics sector.

    With a workforce of 25 associates, turnover in the first years of the third generation is between 2.5 and 3 million Deutschmark, however this has already risen to 15–20 million Deutschmark by 1960. For the first time, the workforce grows to over 100 associates.

  • 1964

    In 1964 the first short cycle laminating line is supplied to Thermopla A.G. in Leutkirch. The product group of short cycle plants is an inevitable creation as the company attempts to use a parallel product to reduce dependence by customers on single-level particle board plants. As a result, the so-called single-level short cycle press lines, lay-up station, tray feeder with a roller belt and the single-level press with a stacking mechanism, including unloading and billet stacking, are developed. One of the first complete plants.

    From then on, over 100 short cycle plants are supplied worldwide in the subsequent years.

  • 1967

    High-precision heavy presses, so-called "single-level high-precision particle board presses", follow in 1967 and become a worldwide success. Imprecise particle board processes required a high level of grinding, i.e. losses. Consequently, these special presses result in approx. 10% more production and improved quality.
    This also results in the ability to produce various wood-based panels, such as MDF and OSB panels.
    In total, 82 of these presses are supplied.

  • 1976

    As early as the beginning of the post-war particle board period there were attempts to manufacture particle boards continuously. All the manufacturers who attempted this went bankrupt. The third generation of Dieffenbachers cautiously goes to work and for the first time builds a continuously operating cold pre-press with circumferential steel belts and pressure rollers. This is a major success in improving quality and capacity. It remains indispensable to the fourth generation of the family to this day.

    The first continuous belt pre-press is developed for Kunz & Co. in Gschwend. To date over 700 belt pre-presses have been supplied worldwide.

  • 1980

    Wolf-Gerd Dieffenbacher enters the family company, beginning the fourth generation. He continues to run the global company to the present day and in his time as managing director he has paved the way for the transition from a press manufacturer to a plant manufacturer.

  • 1981

    At the beginning of the 1980s, the world's largest complete plant with a 34 meter long single-level press for manufacturing particle boards is constructed and supplied to the Kunz company in Canada: a significant step towards plant construction. Additionally, the first 30 m (dual-belt system) single-level particle board plant is shipped to another company (Uniboard) in Canada.

  • 1982

    Even though single-level presses received greater acclaim and were sold in greater numbers, multi-level presses remains a popular Dieffenbacher product. Consequently, in 1982 a 16 level press would make its way to the Grant company in Canada.

  • 1983

    Our subsidiary DNA in Windsor, Ontario, Canada was founded as a new production site for the Dieffenbacher Group. Since then, Dieffenbacher North America (DNA) is not only using the latest planning and manufacturing technology but it can also benefit from synergies with other globally operating Dieffenbacher divisions.

  • 1989

    Together with Kraus Maffei, Dieffenbacher develops the first plant for a combined press/spray process. "Alpha 1", a 5000 ton high-tech plastic press, is designed for General Electric in the USA and shipped there in 1989. A further milestone for the company's Plastics division.

  • 1992

    The subsidiary Dieffenbacher CZ hydraulické lisy, s.r.o, Brno was founded as another production site. Nowadays the subsidiary has become one of the most renowned Czech manufacturers of hydraulic presses up to approx. 12 000kN for the automotive supplier industry, the white goods industry, the forging industry and of specialized press systems for other industries.

  • 1995

    By founding the subsidiaries Dieffenbacher USA Inc. in Atlanta, USA and Dieffenbacher Machinery Services (Shanghai Representative Office) Co. Ltd. in Shanghai, China (since 1999 based in Beijing), the group was given the opportunity to serve its markets in North America and Asia even better. Hence production orders were able to be realized close to our customers.
