1932<\/h2>\n\t\t\t\t

\n Cohline was founded in 1932 in Germany, following an opportunity for its founder, Hans Cohnen, involving the repair of glow plugs on early vehicles. From glow plugs, the company rapidly moved to solving the engineering issues faced by the transmission of fluids around a vehicle and began working with the vehicle manufacturers of the day to help solve the problems with oil, fuel and water transmission.\t\t\t\t<\/p>\n\t\t\t<\/div>\n\t\t<\/div>\n \t\t

1940er<\/h2>\n\t\t\t\t

\n The situation came to a head during World War II, in 1944. Therefore, Hans Cohnen decided to move to Dillenburg in Hesse. He took along his most important machines and materials to continue production for the truck industry.\t\t\t\t<\/p>\n\t\t\t<\/div>\n\t\t<\/div>\n \t\t

1950er<\/h2>\n\t\t\t\t

\n New technologies were introduced due to a high demand in the 50\u2019s. COHNEN took advantage of the aforementioned technology shift and specialized in media-carrying lines. By doing so COHNEN became an important supplier of hose assemblies for the most famous automotive manufacturers.\t\t\t\t<\/p>\n\t\t\t<\/div>\n\t\t<\/div>\n \t\t

1970er<\/h2>\n\t\t\t\t

\n In 1970, Wolfgang Cohnen succeeded his father and led the company to become a modern industrial enterprise. Through the use of new types of connections in production, the expansion continued and numerous innovations were patented. This strengthened the company's position as a supplier. The automotive industry was developing rapidly and COHNEN seized the opportunity to consolidate its place in the market. The big change came with the company's own development of solutions for diverse line systems from injection lines to hydraulic couplings.\t\t\t\t<\/p>\n\t\t\t<\/div>\n\t\t<\/div>\n \t\t
