RHD, a springs’ expert since 1952

RHD has been in the springs manufacturing business since 1952. At the beginning, it was just a little family firm that has only 15 employees. In 1989, the son of the founder Serge Huon, and the director José Dubois went in partnership and changed the history of springs’ design and creation. Nowadays, the firm has 100 professional and skilled employees and has its factory in the northwest of Paris. The computer controlled production process, the mastering of the springs’ use and the technological development of industrial needs, added to more than 60 years of experience have made RHD one of the main actor in spring steel manufacturing and as a supplier.

Lighters, industrial machines, robots, watches, shock absorbers, bottles of perfume, appear on the list of goods whose efficient functioning involves one or several small springs. Springs play a critical yet often ignored role in a very large amount of common objects. Because of exposure to multiple kinds of stresses and small dimension, producing springs requires strict compliance with very high quality standards. For cutting-edge sectors, among which pharmaceutical, high-tech industries, automotive, and other cutting-edge sectors,  it is of the utmost importance that the springs incorporated in their products are of the best quality.
