From the beginning in 1957 our company has been involved exclusively with manufacturing speed reduction gearboxes. Our particular aim has been dedicated to the manufacturers of machinery for plastics and similar products.

In the last 20 years of business, a continuous specialisation in the manufacture of gearboxes for extruders for plastics and similar products enabled our company to have a considerable and continuous development. Today, having two important manufacturing facilities, Zambello Riduttori is a leading company in this field all over the world.
