[4] When the railroad between Herning and Viborg opened in 1906, Sunds got a station, and this set in motion urban development.

The extensive textile industry in the Herning region left a strong mark on Sunds, as the city in the mid-1960s was home to 12 knitwear factories.

[5][4] From the middle of the 20th century, Sunds and the surrounding area were also increasingly influenced by tourism, as Sunds Sø [da] attracted many tourists who, among other things, enjoyed opportunities for swimming and fishing.

Several single-family housing districts emerged, but also a number of industries within a relatively wide range of production branches.

Among the most important is Kyocera Unimerco (founded 1964), which produces tools for the metal, energy and food industries as well as measurement technology,[7] Danfoss Gemina (1987), which manufactures heat exchangers, and Joha (founded 1963), which supplies children's clothing.
