The precision spring manufacturing, a specialty of RHD

Precision spring manufacturing is essential in several industries, only to mention watch making and microtechnology. This spring has been qualified as “precision" because of the fact that irrespective of its type (compression, torsion or other), it is subject to a special treatment to have the maximum strength.


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.

Experienced springs and metal pins manufacturer

The RHD group evolves in the “sharp" domain of precision spring manufacturing for more than 60 years. The CEO of the group, Georges Huon, downright made the industrial spring conception his business. Numerous industrialists use our services and products from now on, that they approve by a large majority because of the quality of the help and the supports we proposed to the customers, the added value which we bring, the fact that we are very fastidious in the initiatives which we undertake during the conception and fabrication process.

The strategy of the group bases itself on a policy of continuous, common investment over several years, the deployment of innovative means of production, a thoughtful choice of the relays of development – a choice more directed towards cosmetic and the automobile, an opening on the world market. The group RHD is from now on a major reference regarding conception of industrial springs and metal pins. In brief, our road map based on the excellence helped us to regain prestige as well on the local and international level.

Precision spring manufacturing is a complex process

Precision spring manufacturing can be made with various materials such as steel, stainless steel or brass. The manufacturing process of this element starts the same way as for all other types of spring.

However, for the “precision" aspect, precision spring has to go through specific operations. Depending on the use to which it is intended, it may be a specific packaging, a zinc flake or ultrasonic cleaning. These springs are very often tailor-made, to meet the required level of accuracy.

RHD, the springs’ specialist

RHD is a family business that was founded in 1952. Over the years, it has become the standard regarding the different types of springs. The company has several specialties, such as pump, but also products suitable for the cosmetics, automotive or pharmacy fields.

Regarding precision spring manufacturing, RHD seeks to provide customer with complete satisfaction by creating prototypes for them. The latter undergo various tests to check their endurance. Afterwards, if test results are conclusive, customers can request a mass or unit production, depending on their needs.

Springs play a critical but often unexpected role in a broad variety of common objects. Among the very numerous items that use one or several small springs to function correctly, one can find bottles of perfume, robots and industrial machines, watches, lighters, shock absorbers. The considerable mechanical and sometimes thermal or chemical stresses to which springs are subjected combined to their small dimension strict compliance with the highest quality standards is mandatory during the manufacturing process. For compagnies in high-tech industries, automotive, pharmaceutical, and other leading-edge fields,  the springs that make up their products are a very serious matter.
