What is the elastic pin?

Elastic pin is also called "Mécanindus". It is a metallic pin that has been made with the metal that is used to make spring. It so has the same mechanic and physical properties as springs but it is used to put two elements together while letting them move enough while it is absorbing the shocks and the weight to which they are submitted.

Numerous assets allowed us to regain prestige both on the French market and on the international market. The group RHD is a pioneer in the "sharp" domain of elastic pin manufacturing for half a century. The president of the group, Georges Huon, made it his business. The strategy of growth the RHD group establishes itself on a road map of continuous, common investment over several years, a better world market position, the deployment of innovative means of production, a thoughtful choice of the crenels of growth - a choice more centred towards cosmetic and the automobile market. RHD is a major reference in design of industrial springs today.


We align ourselves among the reference actors, due to the added value which we bring, the advice and the accompaniments offered to the prospects, the fact that we are very fastidious in the initiatives which we undertake.


Characteristics of the elastic pin


Elastic pin, which is used in the assembly of heavy parts, is available in different dimensions. Thus, it is possible to obtain a standard elastic pin, thinner, lighter and more resistant or thick as required. For the manufacturing of elastic pin, different raw materials are used: stainless steel, chromium or nickel, steel or carbon fibers. The selection of the appropriate raw material depends on the type of pin you want: spiral or cotter elastic pin, etc.


Features and benefits of the elastic pin


The elastic pin is a variation of cold wrapped and rolled pin, which is then cotter in the longitudinal direction. A pin has multiple functions. It can be used to fit or position (in this case one speaks of “positioning pin”) a part to another and act as an axis or safety part.


Thanks to its flexibility, elastic pin can withstand significant shock loads while preventing the other components of the risk of damage, which is not the case with solid pins that alter adjacent elements due to their rigidity. Elastic pin owes its strength and lightness to the type of material used for its design, and heat treatment used by the manufacturer.


The use of elastic pin also allows considerable time saving when fitting parts. Actually, technicians only need to drill a hole without drilling, and then introduce the pin manually or by automatic assembly. These advantages makes the use of elastic pin essential in assembly lines
