On 1st April 1975 Ronald Jabs and Heinrich Pannenbecker establish an engineering office for issuing design sheets and engineering drawings for special machinery and modernisations of machinery according to customer requests.
In September 1978 the engineering office expands to DUMA Maschinen- und Anlagenbau GmbH. Then, business objectives include complete manufacturing, supply and mounting of special machinery and modifications of existing plants.
Ab initio companies of the steel and aluminium industry, materials handling and mechanical engineering companies rank among DUMA's customers.
In 1982 DUMA delivers the first electrostatic oiling machine to Thyssen. To date, more than 250 of these machines have been sold worldwide.
Due to long-lasting, good experiences with DUMA engineering for existing galvanizing plants, at Thyssen the first DUMA air knife is installed in 1988. Since then, more than 30 air knives with roll system have left the workshop in Duisburg.
DUMA equipment is used on all galvanizing products worldwide. Especially, it is applied for the production of high-quality steel sheets as required in automotive engineering.
In 2006 DUMA GmbH enters into a partnership with SMS-Demag AG. Heinrich Pannenbecker retires from business for reasons of age. Now, Ronald Jabs and Peter de Kock are heading the company as Managing directors.
DUMA GmbH continues to operate completely self-dependent.
The range of products comprises
- Air knives for galvanizing, aluminising and tinning lines
- Modernisation of existing plants, whereas all machines are adjusted to the present locations as far as possible,
- Electrostatic oiling machines for strips and sheets ranging from basic machines for the application of rust-protective oiling, lines for the manufacturing of different special oils including Drylube as well as special machinery e.g. positioned above the rewinder of skin pass lines,
- Zinc ingot charging
- Miscellaneous machinery such as finishing lines, strip trimming lines, slitting lines and cross-cut shearing lines
