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.


Compression spring

We manufacture cold-coiled compression springs.

Wave spring

We manufacture wave springs to meet simple or complex requirements.

Tension spring

We manufacture tension springs to meet simple or complex requirements.

Torsion spring

We manufacture torsion springs to meet simple or complex requirements. They can be manufactured from standard machines or specific tools.

Wire form spring

Wire forms are used for a wide variety of applications. Pins, hooks, clips, electrical contact parts, and more, they can be manufactured from standard machines or specific tools.

Flat spring

Flat springs are made using special tools. They can be produced following their morphology on a radial or linear press. RHD has seasoned experts on both types of machines.

Sub-assembly spring

RHD can offer its customers the option of pre-assembly on machine during production in order to shorten the assembly stages and achieve productivity improvements. We are also able to assemble our part with a part supplied by the customer.

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.
