Kopiotyöstö Ltd 1967 – 1989

Kopiotyöstö Ltd was established in 1967. Even at this stage, the production covered plastic, rubber, glass and metal industrial moulds and tools.

From the 1970s onwards, investments were made in exporting tools to countries such as Sweden, Norway and the United States.

In 1983, new premises were built in Riihimäki, Finland with a floor area of 700 m². The company was then 20 years old. It based its own competitiveness on using the most modern technology available.

Purso Ltd 1989–2008

In 1989, Purso Ltd bought Kopiotyöstö Ltd's business. The cell phone boom that began in Finland in the 1990s also led to a rise in tool manufacturing. The tool operations in 1995 were spun off into a separate company, Purso Tools Ltd. Production began on new premises with a floor area of 2000m² at the turn of the century. At the beginning of the 21st century, the company prospered as the mobile phone business was on the rise.

Oitti Tools Ltd 2008-

At the turn of the 21st century, the production directions of the various units of Purso Tools Ltd were reorganised, but the Oitti industrial site continued as a full-blooded tool factory. In 2008, the factory in Oitti was sold to new owners and started operations under the name of Oitti Tools Ltd.
