The company is taken over by the two sons; Jan and Elias Tuin. Before 1940, the shipping and agricultural sector were the most important sectors. After 1945, industrialization takes flight and mechanization in agriculture ensures that woodworking is being said goodbye. Tuin becomes a large forge where for example manure spreaders, fertilizer spreaders and agricultural trailers are made. The government buys snow blades and sand and salt spreaders from Tuin.

The company is taken over by Mr. H. Bos, a son-in-law of Elias Tuin. The company is converted into a B.V. and new customers are found within the industry sector. Machinefabriek Tuin B.V. becomes a supplier of construction, turning and milling work. The machinery is being expanded.

Tuin starts with the engineering of complex machine parts to complete machines and equipment. Therefore, Machinefabriek Tuin becomes a total supplier from design – manufacture – assembly – to installation of machines. The building is being expanded and on 15 May 1987 the new assembly hall is opened in the presence of the 28 employees.

The entire Triumph holding is taken over by mr. Henk Kieft. These include: Machinefabriek Tuin, Masévon, Vernooy from Nieuwegein, Reinders from Groningen and Zilverblank from Vriezenveen.

Masévon moved to Hardenberg and the company name is changed into Masévon Technology. In 2009 the company moved to the new building at the Molensteen in Hardenberg.
