Giacomo Daldi and Luigi Matteucci open their first production facility
The “Società Anonima F.lli Daldi and Matteucci” is established in Milan. The firm has been characterized by those pioneering aspect that every industrial initiative has at that time. The first patents and first inventions are developed.
On 15 April the Joint-stock company “Officine Meccaniche F.lli Daldi and Matteucci” - simply named “DEMM" - is established in Milan in order to produce “general mechanical processing”.
The construction of the Porretta Terme plant starts
The 12,000-square-metre facility is open in Porretta Terme. Its workers are about 1000.
Due to the Second World War, the facilities are temporarily moved to Intra (Verbania) on Lake Maggiore. Production of measuring instruments is started: calipers with different precision levels.
By producing components and gears for aeronautics during WW II, DEMM gets reputation as "Supplier of war material". For this reason, on July 6th, 1944 Porretta Terme plant is bombed and almost completely destroyed.
At the end of the WW II the reconstruction of the Porretta Terme plant begins. This reconstruction ends in 1947 and from that year on, DEMM mechanical production resumes at full speed.
DEMM expands its business by starting the production of tools and machine tools.
DEMM produces its first diesel fuel engine.
DEMM starts the production of mopeds and motorcycles.
On Monza circuit DEMM beats 24 world records with a 50 cc 2-stroke engine fitting a chassis called Siluro.
DEMM wins the Italian Mountain Championship for motorbikes with two engines: a 50 cc 4-stroke DOHC and a 125 cc 4-stroke rods and rockers. Those victories are confirmed in subsequent editions of 1961, 1962 and 1963.
The plant is improved and expanded to reach the current 30,000 covered square meters. At the same time, the decision is made to focus activity on the main objectives, namely the production of gears and the construction of machine tools. In those years the production of some components for Boeing and specifically for the 747 and 767 begins.
The PAI Company of Atlanta becomes part of the shareholders, increasing internationalization
The German company ZF, the largest global group in the production of transmissions, takes over the company and, with large investments, expands the product range.
The “Machine Tools” division is acquired by PFAUTER, which decides to expand its product catalogue with DEMM slotting machines, whose designing and assembling remain in Porretta Terme.
ZF sells DEMM to the PARITEL group.
The company is acquired by GRAZIANO group, the Italian leader in the sector, which expands the Porretta Terme plant production, integrating such a facility into its organization and specializing its activity in specific products and processes.
The company is acquired again by the PARITEL group, with the aim of bringing the DEMM brand back to the original equipment market, tightening new technological alliances and exploiting the synergies coming from the cooperation with other companies in the group.
DEMM is acquired by the holding company Certina AG which decides to focus its activity on products that have historically marked the DEMM brand with the aim of repositioning it among the leading players in the sector.
