Founded in 1986 SISMA® - Sá Couto & Monteiro, SA is focused on the provision of CNC machining services to several industries.

The first years of the company were mainly devoted to a selected network of long-term partnerships in the fields of home appliances, gas valves and hydraulic acessories.
Ever since, the continuous investment in the latest technology expanded our capability and increased our capacity. Currently the company stands out in the provision of parts and components to medical, aerospace, optical and mechanical applications.

In the beginning of the 20th century the company got certified on ISO 9001 quality standard. Later on 2012 our environmental protection concerns have led to environmental certification (ISO 14001). ISO 13485 certification was achieved in year 2015, right after the launch of a new high-demanding project – SISMA Medical. At this time the company undertook in a business area with highly controllable and stable processes along with specialized know-how for the manufacturing of medical devices. SISMA is also trusted by the aerospace industry. EN 9100 is now in implementation phase.

Because we are always challenging to exceed our capabilities we’ve recently expanded our facilities to over 5000 m2 of sustainable environmental solutions. SISMA is proud of offering over 30 years of long-standing expertise in precision machining.
