What you need to know about torsion spring

Torsion springs respond to the needs of a wide variety of sectors. The use and the force to which they will be subjected will define the raw material to be used and the spring’s characteristics. RHD is one of the companies specialized in designing and producing this kind of spring.


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.

RHD, experimented specialist in technical springs

In its early stages in 1952, our company was a small family structure which already concentrated on the creation of springs in any kinds, including torsion springs. In 1989, the association of the son of the founder with his director brought a wind of change on the methods of work, in particular the modernization of the processes of design and production with the aim of supplying products always more reliable and more successful. Besides the use of state-of-the-art material, the implementation of a strategy based on the continuous investment allowed to improve the results of the company.

The fame of RHD in the field of the manufacturing of technical springs is to be proved today more as well on the French market as on the international market. We turn essentially to the expanding sectors of the car, pharmaceutical, mechanical, medical and aeronautical industry, the big consumers of springs, but also particularly demanding regarding quality.

Brief presentation of torsion spring

Torsion spring is designed to restore a couple, and this, with different attachment systems. Thus it can be used both in the field of automotive industry and in the construction industry. Different materials can be used for design: steel alloys, non-ferrous metals, wires rich in carbon or stainless steel. The choice of material should be defined by the intended use of the spring. The wire diameters as well as the shape may also vary. For a particular purpose, torsion spring can go through a specific treatment, which can be a galvanizing, phosphating or a painting.

RHD, a reference in the field of spring production

RHD is a company that has managed to lead the spring manufacturing market. Know-how and rigor are among the elements that explain its success. Always willing to satisfy their customers, all employees of this former family business are constantly and carefully listening to them.

The first step of any relationship between RHD and customers is to understand the needs of the latter. If torsion spring or others are required for a particular use, RHD can tailor same. A document detailing specification is then established, taking into account the appropriate material, compressive stress constraints, adequate size, among other parameters.

Torsion springs and other references provided by RHD are dedicated to various sectors: pharmaceuticals, cosmetics, automotive, armament, electrical equipment… This diversity also helps to reinforce the company reputation at an international level.

Springs are frequently ignored; however, they play an essential role in a very large amount of everyday objects. On the extensive list of goods that do not function correctly without one or several small springs, one can see lighters, bottles of perfume, shock absorbers, watches, robots, but also industrial machines. Because of exposure to various kinds of stresses and little size, the manufacture of springs requires compliance with very high quality standards. Leading-edge sectors, for example automotive, pharmaceutical or high-tech industries place a very high value a high degree of importance on the springs composing their products.
