60 years in springs ‘manufacturing

Numerous assets allowed us to raise our reputation as springs and small compression springs manufacturer at the local and international level. The strategy of development of RHD group establishes itself on a policy of continuous investment, the deployment of means of production answering the current needs, more implication on the international market, an orientation towards buoyant markets, in particular the car industry and cosmetic.


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 evolves in this “sharp" domain for 50 years. We appear even among the most recognized actors, due to the added value which we bring, the fact that we are very pernickety in the steps which we begin, the quality of the advice and the support proposed to the prospects. The RDH group is from now on an great palyer on the market of the manufacturing of industrial springs.

RHD, small compression springs designer and manufacturer

RHD is one of the most known companies in spring manufacture in France and Europe. Leaded by Serge Huon and José Dubois, the firm was initially the Huons family company and has only 15 employees. It is in 1989 that Serge Huon get in partnership with José Dubois and gave a new departure to the company. RHF has now 100 expert staff and send its products in 8 countries. Its experience and skills allows the firm to produce most delicate springs as small compression springs down to 0.1mm threads.

The challenge of producing quality small compression springs

RHD is renowned for producing cold-formed small compression springs with threads ranging from 0.1 to 2mm threads. These are delivered in batches that do not tangle, as a result of the company’s expert handling processes. The spring design is the result of careful consultations with the client, which includes exploring the perfect design for his project in terms of technical specification and budget requirements. Qualities of the spring such as the quality and type of steel, relaxation constraints and compression are all agreed to ensure a perfect match to requirements.

The careful production of small compression springs

Once the technical specification of the required small compression springs is agreed, it is time to move on to the production phase. This takes place in RHD’s 7,000 square metre manufacturing plant just outside Paris. Here, RHD manufactures its springs in a completely computer controlled process, where the customer benefits from total security, knowing the exact stage of his project at any time and enjoying complete traceability of all materials and components used. The company’s production line is based on automobile assembly techniques, with a smooth flow from raw materials right through to dispatch to achieve the most efficient standards of manufacture.

An innovative supplier of small compression springs

RHD is always looking for new ways to improve its products and services and its small compression springs are the result of extensive research and development. The company also offers an Eco Design process that ensures that exacting environmental standards are met by reducing CO2 emissions in production and minimising the volume of raw materials used. RHD also boasts a sophisticated clean room environment, with complete control over temperature and humidity and robotic cleaning to eliminate bacteria and dust. With continuous improvement, RHD leads the way in terms of innovation and quality.

Among the very numerous goods that do not function efficiently without one or several small springs, one can see shock absorbers, watches, robots, but also industrial machines, bottles of perfume, lighters. Springs play a key yet generally ignored role in a very large amount of objects for everyday use. Because of exposure to high mechanical and sometimes thermal or chemical stresses and small dimension, manufacturing springs imposes compliance with very high quality standards. Leading-edge fields, for example automotive, pharmaceutical or high-tech industries attach a very high value to the springs incorporated in their products.
