Created in Terrassa in 1958, Addendum specialises in mechanics, primarily in mechanical transmission. It began by producing gears to equip all types of machinery. Today, our services are much more extensive and concentrate on providing complete, custom-made solutions.
Our transmissions and precision pieces equip many clients from a variety of sectors, such as: public works, aeronautics, maritime, railways, automobiles, industrial machinery, energy, agriculture, feeding, chemicals, packaging, textiles, graphic arts, spare parts, etc.

Throughout the years of the company’s history, our capacities have been increasing and diversifying in order to offer a wider variety of products and better service.
The company has its own, very extensive resources in a production plant of 2.000 m2, and these are complemented by a network of strategic associates, forged over the years.

Our clients, together with the ever-expanding market, have driven Addendum to provide ever-more demanding levels of quality, cost and service. Addendum’s main objective is to offer products of high precision and quality for demanding markets, with highly competitive delivery terms.
