Larger-scale industries arrived in Leatherhead in the first half of the 20th century. In 1928, the Rayon manufacturing company opened a factory in Ermyn Way close to the border with Ashtead parish and was replaced ten years later by the manufacturing plant for Goblin Vacuum Cleaners. Also in the 1930s, a silk-making farm and electrical cable factory were established in the town. Following WW2, Ronson, the US-based manufacturer of cigarette lighters, opened a manufacturing plant at Dorincourt, to the north of the town and relocated to Randalls Road in 1953.
