System Assembly


Metsi Group is an international engineering workshop having factories in Finland and Estonia. Metsi Group’s head and sales office is located in Hausjärvi, Finland. The sales and sourcing office for the Baltic countries is located in Tallinn, Estonia with manufacturing facilities.

Metsi Oy’s history dates back to 1841, when Martin Wetzer, a member of a German industrialist family, founded the Helsinki Mechanical Institute, which served research and industry.


From the outset, the institute was at the forefront of European development in the field, and it was privatized from the Technical Research Centre of Finland VTT in 2000. Shortly afterwards, the company acquired Metsi Oy, a mechanical engineering company founded in 1968, and continued its rapid growth and internationalization under Metsi Oy’s name.


Our goal is to become one the leading contract manufacturing companies in the Nordic countries by 2025.
