The brothers David and Bruno Galletti founded their first craft Company back in 1947 with sound basis in the field of fine machining and industrial machinery construction.
In 1964 they designed and built the first Planetary Mixer P375 based on absolutely innovative mixing techniques, which would have soon been known in the market under the name of «Galletti Planetary».

In 1972 the Company O.M.G. (Officine Meccaniche Galletti S.r.l.) was founded and important investments were made in state of the art machineries and toolings at Ponte Valleceppi (Perugia) factory, allowing new sizes and types of mixers to be produced.
