The 1892 founded company grew heavily in the 1920s and 1930s by acquiring Finnish engineering companies; the products were ships, steel bridges, weighing scales, separators and other machinery. The company's separators were produced under brands Lacta and Milka and they were also produced in Sweden, Denmark and France. By the early 1930s Kone ja Silta held virtually the whole Finnish shipbuilding industry.
Majority of the company ownership was acquired by Wärtsilä iron works in 1935 and Kone- ja Siltarakennus was incorporated into Wärtsilä Group in 1938. The acquisition was prominent due to the significant size difference of the companies, and a major step in Wärtsilä's development as one of the leading engineering companies of Finland.
Production was transferred from Sörnäinen to Joensuu and Järvenpää in the late 1960s and early 1970s. The old factory area is nowadays part of Merihaka.
