Tailor-made spring design

When manufacturing springs, spring design is the first and key step, especially when it comes to specific springs destined to be used under extreme conditions. RHD is ready to design spring according to your requirements, and if needed, to assist you setting the springs specification to perfectly suit your business requirements.


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 group RHD is at present a major reference in springs ‘design and conception of industrial springs. So many assets allowed us to optimize our image on the local plan that world. Numerous industrialists now use our services, which they approve by a large majority because of the added value that we bring, the quality of the advice and the supports offered to the customers, the fact that we show very fastidious in the initiatives which we undertake.

The spring, a pillar of mechanism

Usually, the spring is a key item on which the whole mechanism depends. Therefore, spring design is not a step to be underestimated to avoid any accidents or problems, such as blockages, loosening or sudden dislocation of the spring, etc., while the mechanisms are in use

For spring design, one must first consider the conditions of use of the spring, because all the constraints to which the spring will be submitted will help determine the type of metal and all other parameters that will be taken into consideration for its manufacturing.

RHD, special spring design according to your needs
