The double spring pin

Springs dates back more than 10,000 years with the creating of the bow by hunters. This component is still a key part of many everyday life equipments and in very numerous industrial sectors.  Great variety of springs exists, from compression spring to double spring pin.

A specialist of spring and metal pins manufacturing

Several industrial companies use ask for services from now on, services that they approve by a large majority because of the attention to detail which we show during the process of development of our solutions, the quality of the advice and the accompaniments offered to the prospects, the added value which we bring. The strategy of the group is based on a policy of continuous, common investment over several years, an opening on the world market, an orientation towards crenels with higher added value, in particular the car industry and cosmetic, the deployment of means of production agreeing with the current needs.

The group RHD evolves in this “sharp" domain for 50 years. RHD is at present a major reference on the market of the manufacturing of industrial springs. In brief, a path of excellence that contributes to the restoration of our prestige both on the French market and on the international market.

The use of springs in the industry

Springs are highly requested in the installation of mechanical equipment in all industrial sectors. They are used because of the kinetic energy they produce, but they are also useful to absorb mechanical shocks or to move a mechanism.

There are several types of springs: the compression spring which is set in motion by pushing, the tension spring which has loops and which is intended to undergo extension forces at its ends, the torsion spring which is used for its bending capabilities, the flat spring and its multiples varieties, and double spring pin or double-coil pin.

Springs are used on both large equipment in the smallest electronic components, such as motors watches or mechanical toys.

Among the very numerous items that would be useless without one or several small springs, one can find lighters, robots and industrial machines, bottles of perfume, watches, shock absorbers. Springs play an essential yet often ignored role in a wide variety of familiar objects. Because of the high mechanical and sometimes thermal or chemical stresses to which springs are subjected and their small dimension, springs production processes need to conform to the highest quality standards. For cutting-edge sectors, such as pharmaceutical, automotive, high-tech industries, and other leading-edge fields,  it is essential to use springs of the highest quality in their products.
