We support technology with “know how” which has been gathered during more than 50 years by our technicians and staff in general.

   Modern CNC equipments enable a better production process and ensure dimensional and finishing quality. Computerized support such as the new Production Program (Sipro-Indústria), Quality Program (SIQA), Monitor and Measurement Device Control Program (DMM) and Computer Aided Design (Auto-Cad) help us in preparing success for the future.


   One of the first important achievements of the company was the design and production of a 50 c.c. two-cylinder, two-stroke engine back in 1951.

   In close cooperation with the company Entreposto, Rito developed and produced a differential set and steering box for the new motor vehicle model SADO. In the 80’s and 90’s, Rito also designed and produced synchronized gear and clutch boxes. Such boxes are still part of our daily production.

   Due to the special soil morphology in Madeira Island, we have researched, assessed and produced differential sets and gear boxes with adequate transmission relationships. These innovative achievements were to be built in brand new passenger cars and buses of several automotive brands and models.

   We have participated in the national project for the construction of an electric car, designing and producing a fully innovative rotor wheel transmission system.
