A part of Österberg Group

The corporation was originally established by Mr. Knut Österberg in 1948. At the time, Finland was recovering from war and there was a shortage of nearly everything. Being a machinist by trade, Knut started a small workshop where he built coffee mills, hair rollers and other household items for sale.

In 1953, new and bigger production facilities were built in Panimontie, followed by the first machine for production of plastic details in 1958. In the same year, the production of one of Österberg Group’s most well-known products began: plastic piggy banks for the national Säästöpankki.


In 1966 the company moved to Kruunantie, the location where Österberg Group’s headquarters is still situated today. From this time on, business began focusing more on industrial subcontracting. The first business acquisition was carried out in 1978, when the Österberg family acquired 70 % of the stock in Petsmo, which later changed its name to Petsmo Products. After this, the group has steadily grown through different business acquisitions.


Today, Österberg Group is a traditional family business with a total turnover of approximately 40 million euros.
