Our History. Year by Year

1926
The Foundation
OCEM (Officina Costruzioni Elettro Meccaniche) was established in 1926 in Florence (Italy) by Mr. Ugo Giannelli Sr., the grandfather of today’s company CEO Eng. Ugo Giannelli Jr., who represents the third generation of the company owners. OCEM started its activities manufacturing mechanical and electrical parts and components. At the end of thirties, the company employed about 400 people.

The stop due to the war
During the Second World War, it had to suspend its activities. In August 1944 the doors of OCEM were closed due to the war period in Florence

1953
The New Beginning
Immediately after the war, OCEM resumed its production and in 1953, due to increasing demand of building materials, OCEM introduced innovative HERMETIC HYDRAULIC ROTARY PRESSES for the production of different types of double-layer concrete-agglomerate tiles, such as indoor “Terrazzo” tiles and outdoor tiles.

The Global success
From the mid-50’s, following the growing international markets production requirements, OCEM continued the development of its pressing technology, introducing more powerful and productive double-layer hermetic presses with the capacity to produce always bigger and thicker (up to 100-120 mm) double-layer tiles and slabs (i.e. 600×600 mm, 400×800 mm or even 1000×1000 mm size) with different surface textures.

A New Technology
Alongside the “HERMETIC PRESSING” DOUBLE LAYER technology, in the year 2000 OCEM developed the SINGLE LAYER “FILTER” PRESSING technology to produce Terrazzo tiles and slabs with just one layer (full body), allowing for reduced thickness and weight, especially suited for indoor flooring and external facades applications.OCEM introduced innovative technical concepts, important patents and automations, building a reputation worldwide as a supplier of high-quality, productive and reliable pressing technology, either double or single layer.
