Our history – everything started from a small machine shop
Lehtosen Konepaja was established in the seaside town of Merikarvia in 1923, when Arvo Lehtonen started a small machine shop. When World War II ended, several coincidences caused Arvo to end up in Kokemäki with his engineering workshop.
The mechanical engineering division began its operations in its current location in 1947 with only two employees. Since 1997, the engineering workshop has operated as a limited company. The managing director is now Mikko Lehtonen, and the workshop employs 140 professional workers
