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, a history bound to springs

RHD is one of the European and world leaders of the manufacturing of all kind of springs and of the steel spring manufacturers. The history of the company begins of 1952, it was not at the time of a simple family company of about fifteen employees. Then Serge Huon, the son of the founder went in partnership with his director José Dubois in 1989, a collaboration which allowed to give a new start to the company, making of RHD one of the main suppliers of high-technology industries as the car, cosmetic or air-sea industry.

The growth strategy finalized by the partners allies the efficiency of the continuous investment to the use of modern production tools and to the control computerized of all the process. The support of the customers in the design of the products which exactly meet their needs, the international opening in expanding sectors, the know-how and the experience of successful teams allowed us to place us among the best in the field of the manufacturing of springs.

Features of a steel spring

A steel spring manufacturer must design and implement a strong spring able to absorb mechanical energy or generate movement. The choice of using steel for its production results from the high elasticity of this material, its resistance to corrosion and its good endurance in the face of ongoing stress.

The manufacturer is responsible for finding the best combinations to produce a solid and at the same time quite elastic steel spring, corresponding to the clients’ requirements. In most cases, technical teams must perform extensive research and adjust its production and machines for each order.

RHD, a steel spring manufacturer at the cutting-edge of progress

As a steel spring manufacturer, RHD actively seeks to adapt its products to the customer demand. The dialogue before any project is a particularity of RHD policy. Its technical and business teams work together to find answers to comply with the most demanding marketing requirements while respecting the specifications set and within the established budget line. This results in significant gains of performance.

RHD also focuses on fully computer-managed production. Real-time monitoring of the progress of each project becomes therefore possible, to be able to reach the deadline set. Similarly, RHD owns powerful machines designed to provide quality products, meet the highest demands and significantly reduce time and costs.

On the very long list of goods that cannot function correctly without one or several small springs, one can find shock absorbers, lighters, bottles of perfume, robots, but also industrial machines, watches. Springs play an essential but generally neglected role in a very large amount of objects for everyday use. Because of exposure to multiple kinds of stresses and small dimension, springs manufacturing processes must comply with the highest quality standards. For leading-edge fields, such as pharmaceutical, automotive, high-tech industries, and other cutting-edge fields,  it is essential to use springs of the highest possible quality in their products.
