Since Addendum first started in the business of gear manufacturing over 50 years ago, the company has steadily pursued the goal of instituting the finest work and production practices.
Addendum recently renewed its ISO 9001-2008 certification in the Design and manufacture of gears, transmission systems and precision mechanical components, which was originally obtained in 2008, and later renewed and expanded to the area of design in 2011.
Our continued investment in renewable energy arises from the collaboration of Optima Renovables with the renewed wind energy sector service company, Wind Power Transmissions.
